This deplyment supprts stable perfrmance and availability as yur envirnment grws and yur mnitring needs change. Hw SQLdm wrks with a virtual envirnment Virtual envirnments, such as thse prvided by VMware, allw yu t run multiple instances f cmputers r "virtual machines" n a single, physical hst server. These VMs create a virtual envirnment that enables IT shps t mre fully utilize the hardware they already have, allwing administratrs t maintain fewer physical servers which then cnsume less pwer, take up less real estate, and generate less heat. While there are many advantages t using a virtual envirnment, there are sme disadvantages. One is that a virtual machine currently is nt as fast r efficient as a standalne physical machine. Administratrs must clsely mnitr and manage their virtual envirnments because ver-utilized hardware can quickly and severely impact the perfrmance f their servers, which are cnstantly waiting fr physical resurces t becme available t prcess their wrklads. SQLdm includes VM mnitring t allw administratrs t get a glimpse f what is ging n inside the virtual envirnment in which their SQL Servers are running, t make sure that the VMs and their hst machines are running at peak efficiency. This tpic is a general utline f hw SQLdm wrks in a virtual envirnment and includes links t ther areas where yu can find additinal VMspecific infrmatin.

25 Using the hypervisr t manage resurces On the physical server hsting a virtual envirnment, there is a prcess called the hypervisr r virtualizatin manager running in the backgrund. The hypervisr manages the interactins between the virtual machines and the physical hardware, manages resurces, and then distributes the physical resurces as required by each f the VMs it is hsting. An administratr can intentinally ver cmmit resurces n a physical hst with the idea that it is unlikely that all f the VMs need t utilize all f the resurces n the hst at the same time. The hypervisr is als affected by this shift, and manages any ccasin when all f the active VMs need mre physical resurces than is available frm the hst. Nte that there are ramificatins fr the extra prcessing that is ccurring when the hypervisr is taxed. This additinal prcessing is the verhead fr a virtual envirnment and cnsumes CPU, memry, and netwrk resurces. Hw SQLdm cllects and presents metrics invlving a virtual envirnment The guest perating system n a VM perates n differently than it des when running n a physical machine with full access t all f the resurces at its dispsal. But the machine hsting the VM perates differently because f the virtual envirnment. The physical resurces f the hst are shared with the ther VMs n the hst. Due t the additinal verhead f virtualizatin, and the hypervisr managing cntentin fr resurces, the metrics that the guest OS reads as utilizatin f its resurces are nt entirely accurate as they d nt take int accunt that virtualizatin verhead, nr des it measure that it is waiting n physical resurces t prcess its wrklad. The image belw shws a typical virtualized envirnment. In this envirnment, the hypervisr n each individual hst server cllects the perfrmance statistics and reprts the data back t a central vcenter Server. SQLdm then cllects that infrmatin frm the vcenter Server in rder t shw thse statistics alng with the ther SQL related perfrmance infrmatin.

26 SQLdm displays virtual machine and hst metrics as cllected frm the perspective f the physical hst. In ther wrds, these are the true physical metrics. Whereas, the metrics that SQLdm displays fr the OS n a virtualized machine are what Micrsft Windws calculates as using withut regard t any verhead. Fr example, SQLdm displays the OS CPU Usage at 35%, but metric displayed fr the VM CPU Usage is 38%. This discrepancy results frm the additinal verhead within the hypervisr used t run the VM, and the VM is charged fr the additinal prcessing. Link a mnitred virtual SQL Server instance t the vcenter Server T link a mnitred virtual SQL Server instance t yur vcenter Server, click Tls > VM Cnfiguratin t access the VM Cnfiguratin windw. SQLdm displays the current relatinships between yur available vcenter Servers and yur mnitred SQL Server instances. Fr mre infrmatin abut linking a mnitred virtual SQL Server instance t the vcenter Server, see Cnfigure yur virtual machine cnnectins.

27 VM data cllectin The VM cllectr cnnects t yur vcenter Server during the scheduled refresh fr each f yur mnitred virtual SQL Server instances. If the SQLdm Management Cnsle is pen t the Overview Dashbard r any Resurces view fr a specific instance, data is als cllected based n the Server View Refresh setting in the Cnsle Optins page. In this situatin, it is pssible that the cllectr cnnects t the vcenter Server every few secnds. Yu can adjust the scheduled refresh rate fr a mnitred virtual SQL Server instance by right-clicking the instance name, and then selecting Prperties. Differences in statistics Yu may ntice sme difference in yur statistics, such as SQLdm displaying a higher OS CPU usage than yur VM CPU usage. While the hypervisr manages resurces efficiently, it is pssible that the demand fr physical resurces is greater than what is available. Fr example, a guest OS n a virtual machine submits a batch f wrk t a CPU. Hwever, all f the physical CPUs are cmmitted t ther wrk, s there is n physical CPU available n the hst t prcess the wrk. In this situatin, the VM waits fr a CPU t becme available t prcess its wrk. While it is waiting, the guest OS is unaware f the wait and assumes that it is simply taking lnger fr the CPU t prcess this batch f wrk, and the OS thinks it is using mre CPU pwer than it is actually using. Remember that SQLdm uses the additinal verhead f the hypervisr t calculate the VM metrics. In this situatin, the hypervisr knws the VM is just waiting fr a CPU, s it des nt charge the VM fr CPU prcessing pwer while it is waiting. The result is that the guest OS reprts that it is using the additinal prcessing pwer, hwever the hypervisr simply reprts what is actually used. In this situatin, yur CPU usage metrics that are reprted by Windws are higher than what is reprted by VMware fr that VM. Available metrics related t yur VMs A mnitred virtual SQL Server instance appears in the Servers pane in the same way as a mnitred physical SQL Server instances. Click the apprpriate virtual instance, and SQLdm displays the same dashbard panels as fr a mnitred physical SQL Server instance, but als include specific metrics fr the VM and hst server.

All real-time requests use the SQLdm services t pll the mnitred SQL Server. SQLdm Services SQLdm has three centralized services, the Management Service, the Cllectin Service, and the Predictive Service. These three services reside n the same cmputer. The Management Service perfrms the fllwing primary functins: Prvides real-time data t the SQLdm Cnsle Receives histrical data frm the Cllectin Service fr strage in the Repsitry Raises alerts and sends alert ntificatins The Cllectin Service perfrms n-demand and scheduled cllectin frm the mnitred SQL Servers.

The SQLdm Repsitry als stres cnfiguratin infrmatin, such as the credentials used t mnitr a registered SQL Server instance. TIP SQLdm 8.0 and later requires Micrsft SQL Server 2005 r abve running n the cmputer that hsts the SQLdm Repsitry database fr all installatins. Authenticatin in SQLdm SQLdm uses the same types f authenticatin available in the SQL Server security mdel. When specifying accunt credentials fr the SQLdm services, yu can use Windws Authenticatin r SQL Server Authenticatin. When cnsidering which authenticatin t use, keep in mind that SQL Server Authenticatin is required when n dmain trust exists between the SQLdm Services cmputer and the cmputers hsting the mnitred SQL Server instances. Fr example, if the mnitred SQL Server instances are lcated in an untrusted dmain r behind a firewall, yu must use SQL Server Authenticatin t successfully deply SQLdm. In this case, yu must use the sa accunt r a SQL Server lgin that has System Administratr permissins. Fr mre infrmatin abut these authenticatin types and the SQL Server security mdel, see the Micrsft dcument, Authenticatin in SQL Server.

54 Access the Add Servers wizard Yu can pen the Add Servers wizard frm the SQLdm Cnsle menu by selecting File > Manage Servers, and then clicking Add in the Manage Servers windw. Select a cnnectin type Windws Authenticatin is the recmmended cllectin type as SQLdm uses a number f SQL trace statements that require a trusted cnnectin. When yu select and use Windws Authenticatin, the accunt the SQLdm Cllectin Service is running as is used t cnnect t the SQL Server instance. Select encryptin SQLdm allws yu t designate encryptin methds used t encrypt data between the SQLdm Cllectin Service and the mnitred SQL Server instance. The ptins include SSL (Secure Sckets Layer) r SSL with Trust Service Certificate. Encrypt Cnnectin (SSL) The Encrypt Cnnectin (SSL) ptin adds a flag in the cnnectin prperties that triggers SSL use when the SQLdm Cllectin Service cnnects t a mnitred server that uses SSL t encrypt the data transfer. Fr this ptin t wrk crrectly, yu must cnfigure the mnitred SQL Server instance t use SSL encryptin. Trust Server Certificate (Bypass Certificate Validatin) The Trust Server Certificate (bypass certificate validatin) ptin is available nly after yu select Encrypt Cnnectin (SSL). This ptin allws yu t skip certificate validatin when a SQL Server instance establishes a cnnectin. If SSL n the mnitred SQL Server instance is nt cnfigured t use a certificate that the cllectin service trusts, then the cnnectin is rejected unless yu select the Trust Server Certificate ptin. Select instances t mnitr The Select Servers t Mnitr windw f the Add Servers wizard allws yu t select ne r mre f the SQL Server instances yu want t mnitr using SQLdm. If the name f the SQL Server instance yu want t mnitr des nt appear in the list, type the instance name in the space prvided in the Available Servers area. Yu can als designate specific prts fr yur SQL Server instances by entering a cmma between the instance name and prt number, fr example dmain\instance name,prt The Available Licenses field shws yu the number f instances yur current license permits SQLdm t mnitr. TIP The Select Servers t Mnitr windw lists all the SQL Server instances prvided by yur dmain cntrller. This list can include unsupprted SQL Server instances.

Access the Add Servers wizard Yu can pen the Add Servers wizard frm the SQLdm Cnsle menu by selecting File > Manage Servers, and then clicking Add in the Manage Servers windw. Select a cllectin interval Chsing the apprpriate interval depends n yur specific mnitring needs. When yur SQL Server instance perfrms prly, yu can decrease the cllectin interval s that yu can track changes mre ften. When mnitring a SQL Server instance that has a very heavy client lad and a large number f databases, yu can increase the time perid between cllectins t reduce the pssibility f the frequent cllectins causing a perfrmance impact n yur clients. Mnitring yur envirnment by cllecting query activities When yu experience query timeuts r ther perfrmance issues, yu can cllect query-related activities thrugh the Query Mnitr. Nte that enabling these ptins can degrade perfrmance n the mnitred SQL Server instance because f the additinal data cllectin and strage. T help alleviate degradatin, SQLdm allws yu t select nly thse types f queries yu want t mnitr such as batches, statements, prcedures, and triggers. Additinal threshld fields allw yu t set the levels at which yu cnsider a query as perfrming prly. TIP It is imprtant t remember that nce yu cmplete yur prblem diagnsis, yu can disable the Query Mnitr n the Mnitred SQL Server Prperties windw by selecting the Query Mnitr tab and then clearing the Enable the Query Mnitr check bx. Using advanced Query Mnitr ptins Query Mnitr includes advanced ptins that allw yu t filter applicatins, databases, and SQL text frm cllectin. Use semiclns (;) t separate multiple entries. Yu can als use the percent character (%) as a wildcard.

56 Yu can access this windw by clicking the Advanced buttn in the Query Mnitr tab f the mnitred SQL Server Prperties windw. Cnfigure OS metric cllectin The Cnfigure OS Metric Cllectin windw f the Add Servers wizard lets yu select which type f perating system metrics cllectin yu want t use r whether yu d nt want t cllect any OS metrics frm a SQL Server instance. SQLdm uses OLE autmatin r a direct cnnectin t the Windws Management Interface (WMI) when cllecting OS metrics and service status data n clustered SQL Servers. Cllect Operating System data using direct WMI is selected by default when adding a new SQL Server instance. Select D nt cllect Operating System data if yu d nt want t cllect these statistics. Fr additinal infrmatin abut OS metrics cllectin, see Cnfigure OS metrics mnitring. TIP SQLdm retains yur previus settings upn upgrade if OLE autmatin is the default fr yur mnitred SQL Server instance. After selecting yur methd fr OS metrics cllectin, click Next t cntinue. Access the Add Servers wizard Yu can pen the Add Servers wizard frm the SQLdm Cnsle menu by selecting File > Manage Servers, and then clicking Add in the Manage Servers windw. Permissins necessary fr direct WMI cllectin It is preferred that the WMI user is a lcal administratr n the mnitred SQL Server instance. Hwever, if yu d nt want t grant administratr access, use the fllwing steps t cnfigure remte WMI access in Micrsft Windws: 1. Add the user accunt t the Perfrmance Lg Users and Distributed COM users grups. 2. Grant privileges t WMI. Yu als may need t add the WMI user accunt t the fllwing plicies: Act as part f the perating system Lg n as a batch jb Lg n as a service Replace a prcess level tken Fr mre infrmatin abut using a direct WMI cnnectin, see the Micrsft dcument, Securing a Remte WMI Cnnectin. Disabling OS metric cllectin SQLdm des nt require OS metrics cllectin. Hwever, if yu disable this feature, SQLdm ceases t cllect OS metrics and des nt raise any previusly-assciated alerts. Yu can easily enable OS metric cllectin at any time if yu decide that yu want t cntinue cllecting these metrics.

57 Using direct WMI when the cllectin service is n a different dmain than the SQL Server In envirnments where crss-dmain trust security is enfrced, data frm asynchrnus cllectin is nt returned frm an untrusted dmain t a trusted dmain. As a result, the cllectin service des nt receive the data. If yu select Cllect Operating System data using direct WMI and the machine used fr yur cllectin service is in a different dmain than yur mnitred SQL Server instance, yu must make sme cnfiguratin changes n yur cllectin service machine. If yu d nt make these changes, change yur OS metrics cllectin t Cllect Operating System data using OLE autmatin if yu want OS and disk statistics plus the aut discvery f munt pints. Select an alert template and tags The Select Alert Template and Tags windw lets yu assign an alert template and tags while yu add an instance. Alert templates allw yu t cnfigure generic alert settings t apply t yur servers r grups f servers. Tags are labels that help yu rganize server instances int meaningful grups. T apply an alert template, select the apprpriate template frm the list. If yu d nt have an existing custm alert template, yu can create an alert template after yu add yur SQL Server instance, and then apply the template t yur server. Yu may select ne r mre existing tags frm the list, r create new tags by clicking Add Tag. If yu create an instance befre creating any custm alert templates, SQLdm applies the default alert template autmatically. Yu can then create an alert template and apply it t the server nce the new template is available. After selecting yur baseline cllectin, click Next t cntinue. Access the Add Servers wizard Yu can pen the Add Servers wizard frm the SQLdm Cnsle menu by selecting File > Manage Servers, and then clicking Add in the Manage Servers windw.

Custm cunter scripts run at every scheduled refresh and n-demand n the Custm Cunters view. Fr best perfrmance, custm scripts shuld run in under 30 secnds. If the script takes lnger than tw minutes t execute, timeuts may ccur. Custm SQL scripts must return a single result set with a single numeric field. Additinal fields r nn-numeric values result in an errr. Custm SQL scripts are displayed in Queries tab with "User Defined Cunter" in their applicatin name. The fllwing ptins are set by default fr custm cunter scripts. If yu need t use a different value, particularly anther transactin islatin level, yu shuld add the apprpriate SET statement t the beginning f the script. set transactin islatin level read uncmmitted set lck_timeut set implicit_transactins ff set language us_english set cursr_clse_n_cmmit ff set query_gvernr_cst_limit 0 set numeric_rundabrt ff Access the Add Custm Cunter wizard Yu can pen the Add Custm Cunter wizard by clicking Administratin > Custm Cunters, and then clicking Add in the Custm Cunters view.

Red Indicates the status f the data is at a critical level and requires immediate actin. Blank metrics n the Dashbard If a metric n the Dashbard has n value, r displays as blank, SQLdm is nt able t cllect the crrespnding cunter. Causes f this situatin include: The SQLdm Cnsle has nt captured the metrics. It can take up t tw refreshes fr this capture t ccur. OS metrics are disabled. SQLdm requires direct WMI r OLE autmatin t cllect data.

81 If using OLE autmatin, thse prcedures are unavailable. SQLdm is unable t lcate required OLE autmatin stred prcedures. If cnnecting t WMI directly, the WMI Service is nt running. SQLdm requires that the WMI service is running n the cmputer that hsts the SQL Server instance in rder t cllect OS metrics. The cunters d nt exist n this SQL Server instance. Yu can enable OS metrics mnitring t track the perfrmance f the cmputers n which yur mnitred SQL Server instances are hsted. Refresh yur Dashbard data The Dashbard view is refreshed accrding t the time set in the Server View Refresh field n the Cnsle Optins windw, which is accessible by clicking Tls > Cnsle Optins.

Fr additinal infrmatin abut hw SQLdm displays yur chart data, see Charts. Custmize yur Dashbard view The Dashbard view is custmizable per mnitred SQL Server instance by selecting the panels that are imprtant t view fr that instance. Yu can custmize yur Dashbard view fr the selected SQL Server instance r as the default fr all SQL Server instances added t SQLdm. Using the Panel Gallery When yu install SQLdm, a default Dashbard view is applied t all yur SQL Server instances. The Panel Gallery allws yu t alter yur view s that yu can mnitr the metrics that are mst imprtant. Yu can access the Panel Gallery by selecting the apprpriate SQL Server instance frm the Servers pane, and then clicking Custmize. Once in the Dashbard Designer, click a panel in the Panel Gallery fr SQLdm t display additinal infrmatin abut that panel. Designing a Dashbard view When yu design a Dashbard view, it is imprtant that yu select the metric panels that give yu the best infrmatin fr yur selected SQL Server instance and the current status f that instance. Because SQLdm allws yu t create multiple designs, yu can create ne design with panels specifically fr SQL Server 2000 instances and anther design fr SQL Server 2005 instances. It allws yu t create designs that shw the mst imprtant panels t mnitr when certain events trigger alerts. SQLdm allws yu t chse frm several different layuts f clumns and rws fr yur dashbard design. Yu can then drag and drp panels frm the Panel Gallery t the actual lcatin in the layut where yu want that panel t reside. Yu can als click, hld, and drag panels t re-arrange their lcatin. When yu drag a panel t anther psitin and release the muse buttn, the panel yu mved switches lcatins with the existing panel. Fr example, yur design includes the CPU panel in the upper left crner and the Sessins panel in the lwer right crner. Click, hld, and drag the Sessins panel t the upper left crner, and then release. Nte that the Sessins panel is in the upper left crner and the CPU panel is nw in the lwer right crner. Fr mre infrmatin n available designs, see Design a dashbard view.

82 SQLdm includes several ptins fr yu t use as yur Dashbard view. Yu can als create a design using the available panels, and save the design fr ther peple in yur envirnment t use as their Dashbard view. Fr mre infrmatin n available designs, see Select a dashbard design. Saving a design Once yu are pleased with the selectin and psitining f yur panels, yu can save yur design. In the Dashbard Designer, click Save. SQLdm allws yu t name this design, which is then displayed in the Dashbard Gallery. Fr additinal infrmatin abut saving a dashbard design, see Save a dashbard design. Understanding hw yu can apply a dashbard design SQLdm allws yu t use a design fr a single sessin f the SQLdm Management Cnsle, apply a design t a specific mnitred SQL Server instance, r apply the layut t any ther SQL Server instance including thse yu add later. Yu can use a custm Dashbard view in the fllwing situatins: One-time use SQLdm allws yu t view a custm layut f yur Dashbard view fr a single sessin f the SQLdm Management Cnsle. Fr example, an event in ne f yur instances triggered an alert. Yu want t watch the metric that includes statistics relating t this alert, s yu access the Panel Gallery in the Dashbard Designer. Drag the panel displaying the alert-related statistics t the tp -left crner f yur layut, and then clse the Dashbard Designer. SQLdm displays a message that yu made changes t the current design. Click N t use this design nly until yu clse this sessin f the SQLdm Management Cnsle. SQLdm keeps that panel in the psitin f yur Dashbard view until yu clse the SQLdm Management Cnsle sessin. Even after accessing ther areas within SQLdm, when yu return t yur Dashbard view, the same panel appears in the same lcatin. When yu n lnger want that panel fremst in yur Dashbard view, simply clse the SQLdm Management Cnsle knwing that the default Dashbard view fr that instance appears the next time yu access SQLdm. Set as the default design fr ne r mre instances While the default Dashbard view includes panels that are imprtant t yur mnitred SQL Server instances, the panels may nt be in the rder in which yu want r this design des nt include all f the panels yu want t view. If there are n existing designs yu want t use, access the Panel Gallery t select and mve the panels yu want t the psitins that mst suit yur needs. When yu are dne with yur design, click Save t make sure yu can use this design again. Type a unique name fr this design, verify that this SQL Server instance appears in the Selected Servers area. Yu can add any ther SQL Server instances by selecting the name f that instance, and then clicking Add > t mve the instance t the Selected Servers area. Once yur list f selected instances is cmplete, click OK. Each time yu access the Dashbard view fr this instance, SQLdm displays the infrmatin using this design. Yu can als select an existing dashbard design as the default fr ne r mre mnitred SQL Server instances. On the Server Overview tab, click Custmize, and then in the Dashbard Designer, click Select a Dashbard. Scrll thrugh the available designs until yu find the ne yu want t use fr this mnitred SQL Server instance. Click Select and each time yu access the Dashbard view fr this instance, SQLdm displays the infrmatin in this design.

83 Set as the default design fr all new r unassigned instances SQLdm allws yu t select a design t use as the default fr all new r unassigned mnitred SQL Server instances s that yu have a cnsistent frmat acrss all f yur mnitred SQL Server instances.

Sme events result in multiple alerts, each needing yu t keep a clse eye n as a reslutin is put int place. T help yu mnitr yur SQL Server instances, SQLdm prvides a default Dashbard view that includes cmmnly-mnitred metrics fr the selected SQL Server instance. Yu can imprve the Dashbard view by custmizing yur view t include thse panels mst imprtant t yu. A custmized Dashbard view can help yu keep yur mnitred SQL Server instances frm triggering alerts by prviding yu real-time cverage f crucial metrics. Yu can view yur current Dashbard view by making the apprpriate changes, and then clsing the Panel Gallery pane fr a full view f yur design. Click Panel Gallery t tggle the display f the Panel Gallery selectin pane. Yu can als clse the Panel Gallery by clicking the clse icn in the upper right crner f the pane. Identify which Dashbard panels yu want t include In the Panel Gallery, each panel includes a brief descriptin and a link t access additinal infrmatin abut that panel. T view the descriptin, click the panel fr which yu want t view details. SQLdm als displays a sample graphic shwing the kinds f charts and data available in the panel. Click Mre inf in the descriptin t access the help tpic specifically fr that panel. Nte that yu can use the same panel mre than nce in yur Dashbard design. Because sme panels in the Panel Gallery prvide drp-dwn selectins fr yu t select metrics r ther filters, yu can use the same panel mre than nce in yur Dashbard. This feature is handy when using panels such as the Databases panel because it allws yu t have ne Databases

Unexpected spikes in the buffer and prcedure cache may alert yu t check that yu have enugh memry fr the current pl t functin prperly. Chrnically high cache metrics may indicate the need fr server maintenance, query tuning, r index updates t better handle the nging wrklad. Fr additinal infrmatin, see hw t manage yur Prcedure Cache. If the database cache size seems t be t small fr ptimal perfrmance and there is very little available memry n the system, adding mre memry t the system may increase perfrmance. If there is a lt f available memry n the system and the database cache size is nt grwing beynd a certain pint, the database cache size may be capped at an artificially lw limit. Increasing this limit may increase perfrmance. Page Life Expectancy chart The Page Life Expectancy chart prvides the time in secnds that a page remains in the cache r buffer pl.

Fr additinal infrmatin abut hw SQLdm wrks with virtual machines and cllects metrics, see Hw SQLdm wrks with a virtual envirnment. Metric SQL usage Ttal usage Why it is imprtant A higher SQL usage can indicate that SQL Server is spending t much time prcessing queries. A high ttal CPU usage can indicate that this server des nt have enugh resurces t adequately prcess its current wrklad.

87 Metric VM usage Hst usage Why it is imprtant A high virtual machine usage can indicate that the prcessr pwer allcated t this VM is insufficient fr its current wrklad. A high hst server usage indicates the prcessing pwer n this hst is insufficient t handle the wrklad f the currently active VMs. Prcessr Queue Length gauge The CPU Prcessr Queue Length gauge displays the current value f the prcessr queue length metric. Use this metric t determine hw much wrk is waiting n this server. A high prcessr queue culd indicate a blcking sessin r ther perfrmance issues. Call Rates chart The CPU Call Rates chart breaks dwn the prcessr wrklad int the number f batches, cmpilatins, and transactins cmpleted each secnd, giving yu a detailed view f which activities are resurce-intensive. Metric Batches/sec Cmpiles/sec Re-Cmpiles/sec Transactins/sec Why it is imprtant A high thrughput rate can indicate a higher risk f netwrk, CPU, and resurce issues as the SQL Server perfrmance degrades. A high number f cmpilatins (greater than 100 per secnd) can indicate a high server wrklad r that there is mre recmpilatin verhead than necessary. A high re-cmpilatin rate can indicate excessive re-cmpilatin verhead. A high rate f transactins can indicate a higher risk f resurce issues, such as blcks r lcks, due t the heavier wrklad. Differences in statistics Yu may ntice sme difference in yur statistics, such as yur OS CPU usage being higher than yur VM CPU usage. While the hypervisr manages resurces efficiently, the demand fr physical resurces may be greater than what it has t prvide. Fr example, a guest OS n a virtual machine submits a batch f wrk t a CPU fr executin. Hwever, all f the physical CPUs are cmmitted t ther wrk, s there is n physical CPU available n the hst t prcess the wrk. In this situatin, the VM has t wait fr a CPU t becme available t prcess its wrk. While it is waiting, the guest OS is unaware f the wait and assumes that it is simply taking lnger fr the CPU t prcess this batch f wrk, and the OS thinks it is using mre CPU pwer than it is actually using. Remember that SQLdm uses the additinal verhead f the hypervisr t calculate the VM metrics. In this situatin, the hypervisr knws the VM is just waiting fr a CPU, s it des nt charge the VM fr CPU prcessing pwer while it is waiting. The result is that the guest OS reprts that it is using the additinal prcessing pwer.

Assciate tags with an instance The tag field allws yu t select a tag t add yur server t r add a new tag. Tags help yu rganize server instances int meaningful grups. Select a diagnstic data cllectin interval The data cllectin interval is the amunt f time SQLdm waits between each cllectin f data n the selected SQL Server instance. Yu can set a different interval fr each f the fllwing functins: Cllect diagnstic data and raise alerts (max 30 minutes) The interval between times that the SQLdm Cllectin Service cllects diagnstic data and raises the assciated alerts. Lwer values cause SQLdm t raise alerts mre quickly, but als cause mre frequent refreshes, which increases yur mnitring verhead.

108 Cllect and alert n database metrics (max 24 hurs) The interval between times that the SQLdm Cllectin Service cllects database space-related data and raises the assciated alerts. Lwer values cause SQLdm t raise alerts mre quickly, but als cause mre frequent refreshes, which increases yur mnitring verhead. In envirnments with a large number f databases whse sizes d nt change rapidly, setting the database data cllectin t a lng interval can greatly reduce the mnitring ftprint. By default, SQLdm cllects diagnstic data every six minutes and database data every 60 minutes. Cnsider the fllwing factrs befre selecting yur data cllectin interval: Data cllectin purpse If yur gal with this data cllectin is t identify brad trends and alert n critical dwntime, then a lnger refresh interval is apprpriate. If yu are clsely mnitring yur SQL Server instance fr minute-by-minute changes, use a shrter duratin. Data cllectin frequency When diagnsing specific prblems r when wrking with a prblematic SQL Server instance, a shrt interval lets yu capture enugh data t diagnse the issue. In mst situatins, the default interval prvides sufficient data fr yur diagnstic needs. Nte that SQL Server instances used nly ccasinally may require less mnitring attentin. Ntificatin f existing r ptential prblems Remember that a lwer cllectin interval results in SQLdm raising alerts mre quickly, but als increases yur mnitring verhead. This is true when any setting causes mre frequent refreshes. System resurce impact Althugh SQLdm limits the amunt f system resurce impact when cllecting data, shrt cllectin times n SQL Server instances with large amunts f data culd ptentially cause system perfrmance degradatin. Using the default interval shuld meet yur data cllectin needs while limiting any system resurce impacts. Space needed fr the SQLdm Repsitry A lwer cllectin interval results in mre frequent refreshes which are all stred in the SQLdm Repsitry. Make sure yu have enugh available space t accmmdate these lwer settings. Data spikes SQLdm averages mst metrics ver the timeframe between cllectins. Mre-frequent data cllectin causes increased mvement in averages because f shrt-duratin events. Fr example, a 15-secnd CPU spike has a greater effect n a ne-minute refresh than n a six-minute refresh. Yu can use alert smthing t reduce the impact f data spikes n a peralert basis. Select a server availability verificatin interval The server availability verificatin interval is the amunt f time SQLdm waits between verifying availability n the selected SQL Server instance. If the cnnectin test cllectr des nt cmplete within the time specified in the Alert if the server is inaccessible (max 10 minutes) field, the SQL Server instance is cnsidered unrespnsive. Setting this field t a very lw value can result in false psitive alerts.

109 Cllect extended sessin data The extended sessin cllectin data includes imprtant sessin infrmatin, such as details, lcks and blcks. If this infrmatin is imprtant t yu, make sure the Cllect extended sessin data, including sessin details, lcks, and blcks check bx is selected. Limit the number f DBCC Inputbuffer executins Yu can limit the number f executins perfrmed by the DBCC Inputbuffer, which retrieves the actual input cmmand fr the Sessin Details view, amng thers. Nte that n busy servers, decreasing the Limit executins f DBCC Inputbuffer t value can reduce mnitring impact. Data cllectin credentials SQLdm uses the specified credentials t cllect data frm the mnitred SQL Server instance. Yu can chse t use either Windws authenticatin r SQL Server authenticatin. Windws authenticatin Windws Authenticatin uses the security f the perating system t create a trusted cnnectin nly if the accunt matches a security accunt defined in SQL Server. This security accunt must have sufficient permissins n the mnitred instance t cllect data and OS metrics. SQL Server authenticatin Select this ptin t use the credentials f a specific SQL Server accunt. Select encryptin ptins SQLdm allws yu t designate encryptin methds used t encrypt data between the Cllectin Service and the mnitred SQL Server instance. Yu can chse t use SSL r SSL with Trust Service Certificate. Encrypt Cnnectin (SSL) This ptin sets a flag in the cnnectin prperties that is used when the cllectin service cnnects t a mnitred server that specifies that SSL (Secure Sckets Layer) is used t encrypt the data between the cllectin service and the mnitred SQL Server instance. Fr this ptin t wrk crrectly, cnfigure the mnitred SQL Server instance t supprt encryptin. Trust Server Certificate (Bypass Certificate Validatin) This ptin is available nly when the Encrypt Cnnectin (SSL) is selected. This ptin allws yu t skip the certificate validatin when a SQL Server instance establishes a cnnectin. If SSL n the mnitred SQL Server instance is nt cnfigured t use a certificate that the cllectin service trusts, the cnnectin is rejected unless the Trust Server Certificate ptin is selected.

110 Cnfigure server baseline ptins The Baseline Cnfiguratin tab f the Mnitred SQL Server Prperties windw allws yu t cnfigure yur server baseline ptins. SQLdm calculates a baseline ut f a pl f cllected data based n the selected perid and cllectin interval, and is represented by mean, standard deviatin, minimum, maximum, and cunt statistics. One benefit f using this feature is that SQLdm uses the baseline t prvide alert recmmendatins which yu can use t set effective alert threshlds. SQLdm allws yu t select the date range used t calculate the perfrmance baseline fr ne r mre selected SQL Server instances. The day and time perid fields allw yu t select the days and times n which t base yur alert baseline calculatins. When yur SQL Server instances are nt busy, clear the days and times t remve them frm the calculatin and prvide a mre realistic and accurate baseline. The days and hurs selected apply t bth the Autmatic and Custm baseline selectins. TIP User accunts that include the View privilege can access the Baseline Cnfiguratin windw, but cannt make any changes. User accunts that include the Mdify privilege can make changes t the baseline cnfiguratin f their mnitred SQL Server instances. Access the Baseline Cnfiguratin tab Yu can access the Baseline Cnfiguratin tab f the Mnitr SQL Server Prperties windw by right-clicking the apprpriate mnitred SQL Server instance, and then selecting Cnfigure Baseline. Select a baseline perid The baseline perid yu specify shuld represent a typical peratin f the mnitred SQL Server instances t which this baseline applies.

The three tracked allcatin page types are: Page free space (PFS) Glbal allcatin map (GAM) Shared glbal allcatin map (SGAM) Latch cntentin f this srt is usually an indicatin that yu shuld create mre tempdb data files. In sme situatins, using Trace Flag 1118 may als alleviate tempdb cntentin. Mnitr yur tempdb database SQLdm allws yu t mnitr yur tempdb database with a number f charts and alerts t help yu avid cstly perfrmance issues caused by a full tempdb. The tempdb system database is a wrkspace used t hld temprary user bjects, results created thrugh queries and srts, and ther bjects created by the SQL Server Database Engine. Because f the large amunt f data stred in tempdb, users can run ut f disk space, which causes the entire server and all f its databases t becme unrespnsive. SQLdm seeks t reslve sme f these issues by prviding a mnitring slutin that features a series f tempdb-specific charts, views, and alerts. The tempdb system database, alng with the Master, Mdel, and MSDB databases, is prvided by default with SQL Server and is a shared resurce available t all users cnnected t a single SQL Server instance. Each time yu start SQL Server, it re-creates tempdb based n the Mdel database. Tempdb can fill up quickly when yu are lw n disk space r have a lw maximum size fr database grwth. Certain wrklads may cause excessive space usage r create cntentin in tempdb, which can affect perfrmance n the entire server. TIP Tempdb mnitring is supprted n SQL Server 2005 and abve servers nly. Tempdb versin stre The tempdb versin stre cllects the data necessary t supprt rw versining. Each time a data value changes, a new versin f the rw is created and stred fr as lng as the ldest active transactin needs t access it. Once the rw versin is n lnger needed it is remved frm tempdb by a cleanup jb which runs nce per minute. As a result, lng-running transactins prevent cleanup f lder entries int the tempdb versin stre, causing grwth which can affect perfrmance and cause tempdb t run ut f space.

150 Tempdb cntentin Tempdb resurce cntentin r waits is usually the result f heavy use n t few tempdb files and ccurs when the system attempts t allcate pages. The tempdb cntentin chart displays latch wait time (in millisecnds) fr the allcatin pages f tempdb. The three tracked allcatin page types are: Page free space (PFS) Glbal allcatin map (GAM) Shared glbal allcatin map (SGAM) Latch cntentin f this srt is usually an indicatin that yu shuld create mre tempdb data files. In sme situatins, using Trace Flag 1118 may als alleviate tempdb cntentin. Available alerts Tempdb includes the fllwing specific alerts: Data File Autgrw Lg File Autgrw Lngest Running Versin Stre Transactin (Minutes) Sessin Tempdb Space Usage (MB) Tempdb Cntentin (ms) Versin Stre Generatin Rati Versin Stre Size (MB) Mnitr database cnfiguratin settings The Database Cnfiguratin view allws yu t view the cnfiguratin settings f the databases n the selected SQL Server instance. This view cntains a single grid that includes the cnfiguratin settings fr all databases n the selected SQL Server instance.

Cnfigure alert templates The Alert Templates windw allws yu t cnfigure generic alert settings that yu can apply t servers and grups f servers in yur rganizatin. An event that causes a metric t n lnger meet a cnditin r t exceed a threshld signals SQLdm t raise an alert. Alert templates save yu time and help yu t avid mistakes by simplifying alert cnfiguratin acrss yur envirnment. SQLdm displays the default template name and descriptin in bld text. Applying an alert template t a mnitred server verwrites all existing alert cnfiguratins. Yu can make any custm changes t the specific server's alert cnfiguratin nce the template is applied. If yu make a change t a template that is applied t a server, yu must als reapply the template t that server using the Apply T buttn. TIP Servers are nt permanently attached t an applied alert template. SQLdm des nt prpagate t the mnitred server any changes made t the template unless explicitly applied. A template allws yu t apply the same alert cnfiguratins t mre than ne SQL Server instance. It helps yu avid simple mistakes such as transpsing characters r leaving ut metric details that culd ccur when yu manually cnfigure each server. Alert templates als help yu rll ut changes by making the updates in a single lcatin and then rlling ut the changes acrss yur envirnment. If yu are mre interested in ad hc alert cnfiguratin, remember that yu can use a template t return a server t default settings if yu make any changes that yu later want t revert.

177 Cnfigure alert suppressin In certain envirnments, it is acceptable fr sme metrics t exceed the cnfigured alert threshlds fr very shrt perids f time, fr example ne refresh. Typically these exceptins last less than a minute. If yu are mnitring many SQL Server instances r if the amunt f data cllected is very high, this culd prduce a significant number f alerts. The Advanced Alert Cnfiguratin windw allws yu t limit the number f these alerts that are generated by letting yu input the number f minutes a threshld vilatin ccurs befre an alert is raised, reducing the amunt f alert "nise" yu receive. The amunt f time yu enter here depends n hw critical the metric is in yur envirnment and the amunt f time SQLdm waits between refreshes. If yu enter a time less than that f the refresh, the secnd cnsecutive refresh where the alert is utside the acceptable threshld range prmpts the alert. The fllwing table displays the length f time SQLdm waits befre an alert is raised when the scheduled refresh ccurs every six minutes and varius values are entered: Time entered n the Advanced Alert Cnfiguratin windw Alert is generated 1-5 minutes Secnd Refresh ccurs six minutes after the first encunter f the prblem 6-11 minutes Third Refresh ccurs 18 minutes after the first encunter f the prblem minutes Furth Refresh ccurs 24 minutes after the first encunter f the prblem Cnfigure alert filters - disk drive exclusins By default, certain metrics include all drives within a specific SQL Server instance when mnitring fr events that can trigger an alert.

180 Understanding the dwnside f Autgrw Yu can avid unnecessary lng reads and pr respnse time frm SQL Server by minimizing the number f autgrw events ccurring in yur envirnment. Each time an aut-grwth event ccurs, SQL Server hlds up database prcessing while lking fr disk space fr the additinal data. Usually this new space is nt adjacent t the existing space and causes physical disk fragmentatin. As mre and mre aut-grwth events ccur, the mre the disk becmes fragmented, leading t lnger perids while SQL Server reads the databases. Cnfigure alert filters - database exclusins The Alert Filters tab f the Advanced Alert Cnfiguratin windw allws yu t select databases t exclude frm alerting n the selected metric. Yu can limit the amunt f alert nise generated fr very small databases, which tend t reprt a high fragmentatin rate, r databases that are in single user mde and are usually in use.

Yu can use infrmatinal alerts t ntify an administratr f the state f a particular metric fr a server r trigger secndary prcesses that culd take actin t prevent issue escalatin.

184 TIP Nte that fr certain metrics, using the infrmatinal alert means that yu n lnger receive a warning r critical alert fr events generated by that metric. Please review the situatin befre setting up an infrmatinal alert. Base alerts n past perfrmance One f the mst imprtant steps in setting up SQLdm t successfully mnitr yur SQL Server instances is the cnfiguratin f yur alerts s that yu nly receive alerts n metrics that actually fall utside the typical perfrmance f yur envirnment. SQLdm allws yu t d this by letting yu set a perid f time where the metric ranges cllected fr a set f alerts help determine yur alert threshlds. After data cllectin begins, SQLdm gives yu recmmendatins fr tweaking yur alert threshlds fr the fllwing metrics: Blcked Sessins (Cunt) Client Cmputers (Cunt) Custm Cunters OS Average Disk Queue Length (Cunt) OS Disk Time (Percent) OS Memry Usage (Percent) OS Paging (Per Secnd) OS Privileged Time (Percent) OS Prcessr Queue Length (Cunt) OS Prcessr Time (Percent) OS User Time (Percent) SQL Server CPU Usage (Percent) SQL Server Respnse Time (Millisecnds) T cnfigure yur alert threshlds: 1. Cnfigure the perfrmance baseline. 2. View suggested alert threshlds. Ideally yu shuld wait until the baseline perid is ver. Abut 24 hurs after cllectins begin, SQLdm displays a bar in green with black diagnal lines fr related alerts n the Alert Cnfiguratin windw, as shwn in the fllwing image. This bar represents yu recmmended reference range. 3. As yur perfrmance baseline perid ends, text appears at the tp f yur Alert Cnfiguratin windw regarding available recmmendatins. Click the Alert Recmmendatin text t pen the Alert Recmmendatins windw fr yur SQL Server instance. This windw allws yu t see the threshlds SQLdm recmmends based n the data cllected during yur perfrmance baseline. 4. Either apply the alert recmmendatins r tweak yur threshlds.

185 View suggested alert threshlds SQLdm prvides yu alert recmmendatins t help eliminate false alerts, such as alerts fr metrics that fit within the typical perfrmance f yur server. Yu can view these recmmendatins n the Alert Recmmendatins windw. The Alert Recmmendatins windw is accessed by clicking the "Alert recmmendatins are available fr this SQL Server. Click here t view the recmmendatins nw." text at the tp f the Alert Cnfiguratin windw. This text appears after cllectins have ccurred in which alert threshlds fall within the baseline range. The recmmendatins presented are calculated using yur baseline and adding either 20% r 30% ver the standard deviatin. T edit the percentage ver the standard deviatin used, select the Optins buttn at the bttm f the Alert Recmmendatins windw. T use the Alert Recmmendatins windw: 1. Select the first metric in the Alert Recmmendatins list. The current alert cnfiguratin appears at the bttm f the windw s that yu can easily cmpare that against the recmmended warning and recmmended critical clumns. 2. If yu agree with the recmmendatins and want t apply them t yur metric, check the Apply bx. 3. Click OK. Set recmmended alert ptins Use the Alert Recmmendatin Optins windw t change the percentage abve yur perfrmance baseline that SQLdm uses when recmmending alert threshlds. Either type a percentage abve the baseline fr the Warning and Critical alert threshlds r use the Up and Dwn arrws. Cnfigure alerts fr imprtant cluster events SQL diagnstic manager allws yu t mnitr yur clustered SQL Server envirnment including alerts when a failver ccurs and when the preferred active cluster nde changes. An imprtant way t track clustering events using SQLdm is thrugh the usage f cluster alerts. Cluster Failver Alert By default, this alert is enabled and set t Critical. When a failver ccurs, SQLdm generates an alert and then perfrms ne f the fllwing actins: Clears after 12 hurs if n additinal alerts are generated n the cluster. Generates an additinal alert if anther cluster failver ccurs. Clears instantly when manually cleared. Cluster Active Nde Alert The active nde f the cluster is a nn-preferred nde. Yu can change this setting n the Cluster Settings tab f the Mnitred SQL Server Prperties dialg bx. The Cluster Active Nde is triggered when SQLdm detects that a clustered SQL Server instance is running n a nde ther than the cnfigured preferred nde. Best practices fr using the Cluster Alerts Chse the alert that best reflects yur envirnment and setup ntificatins fr it. Disable the ther alert if it is nt necessary.

186 Organize alerts The Alerts view allws yu t view all alerts fr all f the servers in yur rganizatin. Yu can rganize the alerts in the list using either the Current View r the Filter.

Abut PwerShell Micrsft Windws PwerShell is a task-based cmmand-line shell and scripting language designed especially fr system administratin. Built n the.net Framewrk, Micrsft Windws PwerShell helps IT prfessinals and pwer users cntrl and autmate the administratin f the Windws perating system and applicatins that run n Windws. Windws PwerShell furnishes an perating envirnment fr cmmands that include cmdlets, functins, filters, scripts, aliases, and executables (applicatins). The main cmmand type used in this envirnment is the cmdlet, with certain cmdlets made available nly thrugh Windws PwerShell prviders that allw access t stred data. Windws PwerShell perates within a hsting applicatin (the default is pwershell.exe) that expses a cmmand line t the user, and uses a hst interface t cmmunicate with the cmmands invked by the cmmand line. Yu can use a cnsle applicatin, Windws applicatin, r a Web applicatin as the hsting applicatin. In mst cases, the hsting applicatin uses its Main functin t interact with the Windws PwerShell runtime thrugh the internal hst interface; hwever, a hsting applicatin can ptinally supprt its wn custm hst by implementing the PSHst class alng with ne r mre related user interface classes. Tgether, these classes allw direct cmmunicatin between the applicatin and Windws PwerShell cmmands. Fr mre infrmatin abut Windws PwerShell, see SQL Server Bks Online.

242 Mnitred metrics SQLdm cllects a number f SQL Server and perating system perfrmance metrics t help yu mnitr, alert, and reprt n yur system health. SQLdm includes a number f metrics fr yur use, such as: Batches Received (Per Secnd) Blcked Sessins (Cunt) Buffer Cache Hit Rati (Percent) Client Cmputers Cmpiles (Per Secnd) Data Used (Percent) Database Status Disk Queue Length Disk Time (Percent) I/O Waits Lck Waits Lg Flushes Lg Space Used (Percent) Memry Page Faults (Per Secnd) Memry Paging Memry Waits Other Waits Packets Received (Per Secnd) Packets Sent and Received Packets Sent (Per Secnd) Page Reads (Per Secnd) Page Writes (Per Secnd) Percent f SQL Server Data Space Used Percent f SQL Server Lg Space Used Physical Page Reads and Writes Prcessr Queue Length Re-cmpiles Per Secnd Signal Waits SQL Server Batches Received SQL Server CPU Usage SQL Server Lg Space Used (Percent) SQL Server Memry Usage SQL Server Respnse Time Ttal Memry Usage Transactin Lg Waits Transactins (Per Secnd) Wait type categry - Backup

243 Wait type categry - I/O Page Latch Wait type categry - Lck Wait type categry - Memry Wait type categry - Nn-I/O Page Latch Wait type categry - Nn-Page Latch Wait type categry - Other Wait type categry - Transactin Lg Batches Received (Per Secnd) The Batches Received (Per Secnd) metric cunts the ttal number f batch requests that the SQL Server cmputer receives per secnd. This rate is a measurement f thrughput n the prcessr. This metric uses the cunter Batch requests/sec frm the SQL Server SQL Statistics cunter bject. On SQL Server 2000 instances, this cunter is available thrugh sysperfinf. On SQL Server 2005 r later instances, this cunter is available thrugh sys.dm_s_perfrmance_cunters. T track this metric, use the CPU Call Rates chart in the CPU dashbard f the Server Overview tab. While this cunter has n gd r bad value, each f these T-SQL batches must be: 1. Transmitted t the server using the netwrk. 2. Parsed by SQL Server t check syntax. 3. Have an executin plan cmpiled. 4. Executed accrding t the executin plan. 5. Have the results transmitted back t the client cmputer r Web site. Reduce the number and impact f T-SQL batches In this situatin, yu shuld reduce the number f T-SQL batches and the impact f each as much as pssible by: Reducing the size and cmplexity f the T-SQL by creating a stred prcedure cntaining the cmmands yu want executed and then simply calling it in the T-SQL batch. This apprach reduces the size and cmplexity f the T-SQL batch, which means less netwrk traffic and less CPU time cnsumed prducing a cmplex executin plan. Once yu mve mst f the T-SQL cde int stred prcedures, cnsider gruping as many f thse calling T-SQL cmmands int a single netwrk batch, if pssible. Als cnsider redesigning the applicatin t call nly thse stred prcedures yu need t cmplete an applicatin functin all frm within ne batch rather than sending each EXECUTE statement t execute separately in its wn batch. This strategy reduces netwrk queues dramatically as better use is made f the default 4 KB netwrk packet size. Blcked Sessins (Cunt) The Blcked Sessins (Cunt) metric cunts the number f sessins n the SQL Server instance blcked by ther sessins hlding requested lcks. By default, a blcked sessin waits frever fr a lck. Yu can change this behavir by adding SET LOCKTIMEOUT t the tp f the first T-SQL batch after yu make a cnnectin.

244 Buffer Cache Hit Rati (Percent) The Buffer Cache Hit Rati (Percent) metric calculates the percentage f data pages SQL Server fund in memry withut reading the data frm the disk subsystem. This value is measured by reading the buffer cache hit rati frm sysperfinf. The higher this value is the mre efficiently the system is running. Reduce the percentage f memry used by SQL Server Once SQL Server is up fr at least 30 minutes, use the fllwing slutins if values lwer than 85% regularly ccur: Add mre physical memry (RAM) t the cmputer. If yur site makes use f extended stred prcedures that are infrequently called, then after calling them, issue a DBCC DLLNAME (FREE). Once an extended stred prcedure is called, it remains in memry until SQL Server is shut dwn even if it is never again called, which then wastes available memry. A DBCC dllname (FREE) releases that memry fr use by bth the prcedure cache and Data Pages, which has a significant psitive effect n bth the Prcedure Cache Hit Rati and the Buffer Cache Hit Rati. Execute SP_HELPEXTENDEDPROC t view the extended stred prcedures currently laded in memry by SQL Server. Allwing SQL Server t cnsume mre f the available memry, making sure that OS Paging des nt increase. Limit SQL Server cmputers t perfrming nly SQL Server wrk. Stp any unnecessary prgrams, such as allwing the cmputer t act as either a primary r backup dmain cntrller. If the cmputer is running multiple instances f SQL Server, then cnsider placing each instance n a separate physical cmputer. Client Cmputers The Client Cmputers metric calculates the number f distinct cnnected netwrk adapters currently using the SQL Server instance. This value is measured by getting the cunt f prcesses frm distinct cmputers in sysprcesses table. SQL Cmpilatins (Per Secnd) This metric calculates the number f SQL cmpilatins per secnd, including statement-level re-cmpilatins. This metric uses the cunter SQL Cmpilatins/sec frm the SQL Server SQL Statistics cunter bject. On SQL Server 2000 instances, this cunter is available thrugh sysperfinf. On SQL Server 2005 r later instances, this cunter is available thrugh sys.dm_s_perfrmance_cunters. A high number f cmpilatins (greater than 100 per secnd) can indicate a high server wrklad r that there is mre recmpilatin verhead than necessary. T many cmpilatins can impact a server s perfrmance. Data Used (Percent) The Data Used (Percent) metric calculates the size f all data files used as a percent f the added allcated size f all data files. In a typical medium-t-large-scale OLTP envirnment with a data file size f ver 50 GB, this value slwly increases ver time in a linear fashin with the ppulatin f any available histry tables.

245 Reduce the percentage f data used If yur site experiences a sudden sharp increase in this value f ver 10% in an hur, investigate the issue t fully understand the underlying causes which ften lead t pr perfrmance. Pssible causes include: A large number f rws were inserted int a table. If s, then make sure that the table is nt fragmented due t this peratin. T verify, run DBCC SHOWCONTIG. An index with very pr cardinality (uniqueness) was added t a large table. Indexes with pr cardinality ften exceed the size f the underlying table itself and in almst all cases are nt used by any SQL Server query. A large number f rws were incrrectly changed by perfrming an insert f a new rw fllwed by a delete f the ld rw. Althugh the net effect f the change is essentially the same number f rws; the database wuld have grwn significantly in size and require yu t issue a DBCC SHRINKDATABASE. It is likely that the table is als fragmented because the inserts were dne befre the deletes s run DBCC SHOWCONTIG. Always delete the ld rws ut f a table first befre inserting the new rws; therwise the tables are fragmented mre quickly, databases increase in size, and the perfrmance f the transactins is degraded due t the large number f page splits the table had t underg. Database Status The Database Status metric indicates the peratinal status f the database, such as Nrmal, Offline, r Suspect. Yu can select the database status fr which yu want t receive alerts. Disk Queue Length The Disk Queue Length metric cunts the average number f system requests that are waiting fr disk access n the cmputer hsting the SQL Server instance. The Disk view n the Resurces tab allws yu t track yur Disk Queue Length, alng with ther key disk statistics, ver a perid f time n the cmputer hsting yur SQL Server instance. Reasns why this metric has n value SQLdm is unable t cllect the crrespnding cunter due t ne f the fllwing reasns: It usually takes tw refreshes t begin ppulating the Disk Queue metric, which ccurs within a few secnds. OS Metrics cllectin is disabled r nt wrking prperly. Yu must enable OS Metrics cllectin fr SQLdm t cllect hardware perfrmance metrics. Lightweight Pling is enabled. SQLdm cannt cllect OS metrics if Lightweight Pling is enabled n the SQL Server instance. The cunter des nt exist n this SQL Server instance. Disk Time (Percent) The Disk Time (Percent) metric calculates the percentage f elapsed time during which all the disks were busy servicing read and write requests n the SQL Server cmputer. This cunter is measured by subtracting the Disk Idle Time percent frm 100. The WMI bject WIN32_PERFRAWDATA_PERFDISK_PHYSICALDISK prperty PERCENTIDLETIME is measured t get Disk Idle Time percent. Reduce disk time If this metric value regularly exceeds 75%, cnsider the fllwing slutins:

246 Check OS Paging t make sure that paging frm/t the swap file is nt causing these IOs. Distribute the data and lgs ver mre disks. Replace disks with faster disks. Add mre memry if the main cause is Disk Reads. Switch frm a RAID 5 t RAID 10 slutin if Disk Writes make up mre than 20% f ttal disk access. Mve nn-sql Server applicatins t anther cmputer. If the cmputer is running multiple instances f SQL Server, cnsider placing each instance n a separate cmputer. I/O Waits The I/O Waits metric calculates the length f time that SQL Server prcesses had t wait fr I/O t becme available. This rate is a measurement f thrughput n the SQL Server cmputer prcessr, as determined by the SQL Server wrklad. Lck Waits The Lck Waits metric calculates the length f time that SQL Server prcesses had t wait fr a resurce lck t reslve. This rate is a measurement f thrughput n the SQL Server cmputer prcessr, as determined by the SQL Server wrklad. Lg Flushes (Per Secnd) The Lg Flushes (Per Secnd) metric reads LOG FLUSHES/SEC frm sysperfinf. Each time data changes, the changes write t the lg cache, which resides in memry. Under certain cnditins, this lg cache is flushed t disk. These situatins include: A cmmit r rll back f an explicit r implicit transactin. A CHECKPOINT statement executin. SQL Server issues an autmatic checkpint. The Lg Cache is full and needs emptying. Reduce lg flushes On an OLTP system that runs relatively small transactins (n average, less than 40 rws added, changed, r deleted per transactin), the number f Lg Flushes shuld nt exceed SQL Batches by mre than 40% during perids f high activity. If yu exceed this percentage, then ne f the fllwing abnrmal cnditins exists: T-SQL batches sent fr executin cntain a number f individual data manipulatin statements (inserts, deletes, r updates) nt enclsed within a transactin. Large batch jbs which update significant amunts f data are run during the day. Deadlcks r Lck Timeuts are causing a number f transactins t rll back r execute a ROLLBACK TRANSACTION statement. Yur Recvery Interval parameter is t lw. Raise this parameter t minutes. An explicit CHECKPOINT statement is executed within sme transactins. If yu need t delete the entire cntents f a table, use the TRUNCATE TABLE statement instead f DELETE as it prduces less lg flushes. If yu implement the previusly-mentined measures and the Lg Flushes still greatly exceed 140% f SQL Batches, then cnsider:

247 Switching yur RAID array frm a RAID 5 t a RAID 10 slutin. Each write IO results in tw writes using RAID 10 vs. 4 fr RAID 5 (100% mre efficient with writes). As lng as the RAID cntrller has sme frm f battery backup, then switch its cache mde frm Write-thrugh t Writeback, as this setting increases the system's ability t handle write IOs by an rder f magnitude. Adding mre cache memry t the RAID cntrller. Memry Page Faults (Per Secnd) This metric calculates the page fault rate fr all prcesses n the SQL Server cmputer. The WMI bject Win32_PerfRawData_PerfOS_Memry prperty PagesPersec is measured t get this value. Fr ptimal perfrmance, the page fault rate shuld either be either 0 r very lw. Reduce memry page faults Use the fllwing slutins t reduce the page fault rate if it rises abve 100 fr a perid f time lnger than a mmentary spike: Decrease the memry being used by stpping unnecessary prgrams such as the Print Spler frm running n the dedicated SQL Server cmputer. Yu shuld als eliminate activities such as the server acting as a PDC r BDC and (as a last resrt) reducing the amunt f memry SQL Server may cnsume. Add mre physical memry n the cmputer. If the cmputer is running multiple instances f SQL Server, then cnsider mving each instance t a separate physical cmputer. Memry Paging The Memry Paging metric cunts the number f pages being swapped in and ut f memry per secnd. The Memry view n the Resurces tab allws yu t track paging and ther key memry statistics ver a perid f time. Reasns why this metric has n value SQLdm is unable t cllect the crrespnding cunter due t ne f the fllwing reasns: It usually takes tw refreshes t begin ppulating the Memry Paging metric, which ccurs within a few secnds. OS Metrics cllectin is disabled r nt wrking prperly. Yu must enable OS Metrics cllectin fr SQLdm t cllect hardware perfrmance metrics. Lightweight Pling is enabled. SQLdm cannt cllect OS metrics if Lightweight Pling is enabled n the SQL Server instance. The cunter des nt exist n this SQL Server instance. Memry Waits This metric calculates the length f time that SQL Server prcesses had t wait fr SQL Server memry t becme available. This rate is a measurement f thrughput n the SQL Server cmputer prcessr, as determined by the SQL Server wrklad. Other Waits This metric includes any additinal waits ccurring n this SQL Server utside f the fllwing wait categries: I/O Lcks

248 Memry Signal Waits are a measurement f thrughput n the SQL Server cmputer prcessr, as determined by the SQL Server wrklad. T get mre details abut mnitred wait statistics, see the Server Waits view, and review the Micrsft Best Practice Article SQL Server Waits and Queues. Packets Received (Per Secnd) This metric is calculated as a rate between tw refreshes f the value f the system statistical If this value is cnsistently high, cnsider changing the packet size. Packets Sent and Received This metric cunts the number f packets being sent and received, per secnd, n yur SQL Server instance. Packets Sent (Per Secnd) This metric is calculated as a rate between tw refreshes f the value f the system statistical If this value is cnsistently high, cnsider changing the packet size. Page Reads (Per Secnd) This metric cunts the number f physical reads the disk sub-system perfrms t bring SQL Server database pages int the data (buffer) cache. Fr the first few minutes after yu start r restart SQL Server, almst any request fr data is retrieved frm disk. As the data cache fills, these requests are reduced. This value is measured by reading PAGE READS/SEC frm sysperfinf. Currently, even the fastest disks can supprt a maximum sustained rate f arund nly 85 randm IOs per secnd. T determine if yur IO subsystem is "flded," perfrm the fllwing calculatin: On RAID 10: ((Page reads + read ahead pages + ((page writes + checkpint pages + lazy writes + lg flushes) X 2)) / number f disk spindles in RAID array) must be < 65. Reduce page reads If the page reads rate exceeds 65 fr mre than five secnds every 20 minutes, then cnsider these slutins: Add mre physical memry (RAM) t the cmputer. If yur site makes use f extended stred prcedures that are nt called very ften, then after calling them, issue a DBCC DLLNAME (FREE). Once an extended stred prcedure is called, it remains in memry until SQL Server is shut dwn even if it is never called again. This is tremendusly wasteful in terms f available memry and a DBCC DLLNAME (FREE) releases that memry fr use by bth the prcedure cache as well as the Data Pages which have a significant psitive effect n bth the Prcedure Cache Hit Rati as well as the Buffer Cache Hit Rati. In rder t view the extended stred prcedures currently laded in memry by SQL Server, execute SP_HELPEXTENDEDPROC. Allw SQL Server t cnsume mre f the available memry (making sure that OS Paging des nt increase). If yu are running large, batch-style reprting queries n the OLTP server, then large numbers f data pages are flushed frm cache causing much additinal IO verhead. In this situatin, set up a separate SQL Server Reprts cmputer t service all but the smallest reprts. Yu can feed this Reprts Server via backups and Lg Shipping frm the OLTP server.

249 Stp unnecessary prgrams (such as the Print Spler r activities such as the database server acting as either a BDC r PDC) frm running. If the cmputer is running multiple instances f SQL Server, then cnsider placing each instance n a separate physical cmputer. Page Writes (Per Secnd) This metric cunts the number f physical database writes the disk sub-system perfrms. This value is measured by reading PAGE READS/SEC frm sysperfinf. Currently, even the fastest disks can supprt a maximum sustained rate f arund nly 85 randm IOs per secnd. T determine if yur IO subsystem is "flded," perfrm the fllwing calculatin: On RAID 5: ((Page reads + read ahead pages + ((page writes + checkpint pages + lazy writes + lg flushes) X 4)) / number f disk spindles in RAID array) must be < 65. On RAID 10: ((Page reads + read ahead pages + ((page writes + checkpint pages + lazy writes + lg flushes) X 2)) / number f disk spindles in RAID array) must be < 65. Reduce page writes If the page writes rate exceeds 65 fr mre than five secnds every 20 minutes, then cnsider the fllwing: Add mre physical memry (RAM) t the cmputer. If yur site makes use f extended stred prcedures that are nt called very ften, then after calling them, issue a DBCC DLLNAME (FREE). Once an extended stred prcedure is called, it remains in memry until SQL Server is shut dwn even if it is never called again!

Stp unnecessary prgrams (such as the Print Spler r activities such as the database server acting as either a BDC r PDC) frm running. If the cmputer is running multiple instances f SQL Server, then cnsider placing each instance n a separate physical cmputer. Percent f SQL Server Data Space Used This metric calculates the percentage f the allcated disk space fr databases that is being used by the SQL Server instance. The ttal size allcated t the databases is the sum f unused space, data space, and index space. Data space includes leaf level clustered index pages, since these pages are the data pages. Index space excludes the leaf pages f clustered indexes. The Files view n the Databases tab allws yu t view detailed data file infrmatin including the data size and the percentage f allcated file size being used n each f yur databases.

250 Percent f SQL Server Lg Space Used This metric calculates the percentage f the allcated space fr lgs that is currently being used. The Files view n the Databases tab allws yu t view detailed lg infrmatin including the lg size and the percentage f allcated file size being used n each f yur databases. Physical Page Reads and Writes This metric cunts the number f physical page reads and writes t disk frm the SQL Server instance. Prcessr Queue Length This metric cunts the number f ready threads in the prcessr queue n the cmputer that hsts the SQL Server instance. The WMI OBJECT WIN32_PERFRAWDATA_PERFOS_SYSTEM prperty PROCESSORQUEUELENGTH is measured t get prcessr queue length cunt. Re-cmpiles (Per Secnd) The Re-cmpiles (Per Secnd) metric calculates the rate f re-cmpiles n yur mnitred instance, using the cunter SQL Re- Cmpilatins/secfrm the SQL Server SQL Statistics cunter bject. On SQL Server 2000 instances, this cunter is available thrugh sysperfinf and represents the rate f batch re-cmpilatins per secnd. On SQL Server 2005 r later instances, this cunter is available thrugh sys.dm_s_perfrmance_cunters and represents the rate f statement-level re-cmpilatins per secnd. Typically, this metric value is lw. A high re-cmpilatin rate may be a sign f excessive re-cmpilatin verhead. Causes f recmpiles include varius events including schema changes, statistics updates, and explicit calls t WITH RECOMPILE. Excessive re-cmpilatin impacts yu server perfrmance. Signal waits This metric calculates the length f time that SQL Server prcesses had t wait fr CPU time after the assciated resurces became available fr prcessing. This rate is a measurement f thrughput n the SQL Server cmputer prcessr, as determined by the SQL Server wrklad. SQL Server Batches Received (Per Secnd) The SQL Server Batches Received (Per Secnd) metric cunts the number f T-SQL batches that SQL Server receives fr executin every secnd. This value is measured by reading batch requests/sec frm sysperfinf. While this cunter has n gd r bad value, each f these T-SQL batches must: 1. Be transmitted t the server using the netwrk. 2. Be parsed by SQL Server t check syntax. 3. Include a cmpiled executin plan. 4. Include an executed executin plan. 5. Transmit the results back t the client cmputer r Web. Yu must minimize the number and reduce the impact f these T-SQL batches as much as pssible by:

251 Reducing the size and cmplexity f the T-SQL by creating a stred prcedure cntaining the cmmands yu want executed, and then simply calling it in the T-SQL batch. This actin reduces the size and cmplexity f the T-SQL batch, resulting in less netwrk traffic and CPU time cnsumed prducing a cmplex executin plan. Gruping as many calling T-SQL cmmands int a single netwrk batch after yu mve mst f the T-SQL cde int stred prcedures. Redesign the applicatin t call whatever stred prcedures yu need t cmplete an applicatin functin all frm within ne batch rather than sending each EXECUTE statement t execute separately in its wn batch. This actin dramatically reduces netwrk queues as yu make better use f the default netwrk packet size f 4 KB. SQL Server CPU Usage (Percent) The SQL Server CPU Usage (Percent) metric calculates the percentage f CPU time used by the SQL Server instance. This value is calculated by the percentage f time in a query spent by the I/O, idle, and CPU times n the cmputer that hsts the SQL Server instance. T track this metric, use the CPU Usage chart in the CPU dashbard f the Server Overview tab. Lwer SQL Server CPU usage If this value regularly exceeds 75%, cnsider taking the fllwing actins: Reduce the number f SQL re-cmpilatins, as they are CPU intensive. There are many reasns that an bject such as a stred prcedure is recmpiled. Yu can remve mst f these reasns by careful cding. Make sure that all T-SQL statements (whether in a Stred Prcedure, Trigger, r Ad Hc statement) that reference bjects fully qualify the bject referenced. Fr example: SELECT * FROM Nrthwind.db Emplyees is a fully-qualified bject reference whereas SELECT * FROM Emplyees is a prly-qualified bject. Yu can reuse the executin plans f fully-qualified bjects "as is," whereas plans where yu either cannt reuse the nt fully-qualified bjects r, if they are reused, then they are subject t a highly restrictive COMPILE lck while SQL Server determines if all f the bjects referenced in the T-SQL cde have the same wners as the executin plan currently in cache. Bth f these situatins cnsume a significant amunt f CPU time. Lg Space Used (Percent) The Lg Space Used (Percent) metric calculates the added size all lg files used as a percent f summed allcated size f all data files. A transactin lg cntinues t grw until its inactive prtin is truncated. Transactin lg truncatin ccurs because either: the BACKUP LOG statement successfully cncluded, r if the database is using the Simple Recvery Mdel, then a CHECKPOINT T-SQL statement executes r SQL Server perfrmed an internal autmatic CHECKPOINT. SQL Server perfrms this actin if the lg reaches 70% full r when SQL Server determines the length f time t recver frm the lg, in the event f a failure, exceeds the Recvery Interval ptin. Only the inactive prtin f the lg is ever remved. The inactive prtin f the lg is the prtin f the lg up t but nt including the start date/time f the ldest pen transactin. N matter which methd is used t truncate the lg, if there is a perpetually pen transactin then the lg cntinues t grw in size until it cnsumes all available disk space. Reduce the percentage f the lg used If yur transactin lg size cntinues t grw despite issuing BACKUP LOG r CHECKPOINT statements, check fr a rgue transactin. Begin yur research by srting the Last Batch clumn n the SQL Prcesses grid int ascending mde such that the prcesses cntaining the ldest batches appear first. Scrll dwn the list until yu find the first user prcess with a nn-zer

252 number f transactins in its Trans clumn, and then kill this prcess. Once this is dne, perfrm a CHECKPOINT r BACKUP LOG t reduce the Lg File Used Size. SQL Server Memry Usage This metric calculates the percentage ttal memry being used n the cmputer hsting the selected instance by SQL Server. The Memry view n the Resurces tab allws yu t track the SQL Server memry usage, alng with ther key memry statistics, n the cmputer hsting yur SQL Server instance. SQL Server Respnse Time (ms) This metric calculates the time (in millisecnds) that SQL diagnstic manager currently needs t send a simple SQL cmmand t the SQL Server instance, have it prcessed, and receive the returned result set. Typically, this value shuld average belw 2000 ms fr a well tuned netwrk and server. Average values in excess f 2000 ms indicate either an excessively busy netwrk segment r a stressed SQL Server. Ttal Memry Usage This metric calculates the percentage f physical memry and virtual memry Windws is using. The Memry view n the Resurces tab allws yu t track the Ttal Memry usage alng with ther key memry statistics n the cmputer hsting yur SQL Server instance. Transactin Lg Waits This metric calculates the length f time that SQL Server prcesses had t wait fr the transactin lg t becme available. This rate is a measurement f thrughput n the SQL Server cmputer prcessr, as determined by the SQL Server wrklad. Transactins (Per Secnd) This metric calculates the ttal number f transactins per secnd acrss all databases n the mnitred instance. This metric uses the cunter Transactins/sec frm the SQL Server Databases cunter bject and _Ttal instance. On SQL Server 2000 instances, this cunter is available thrugh sysperfinf. On SQL Server 2005 r later instances, this cunter is available thrugh sys.dm_s_perfrmance_cunters. This rate is a measurement f thrughput n the prcessr, as determined by the SQL Server wrklad. Althugh this rate measures activity within a transactin, and a higher transactin rate indicates a higher risk f resurce issues, it des nt accunt fr all activity n the SQL Server cmputer.

Distributin Latency (Secnds) alert The Distributin Latency (Secnds) alert tracks the amunt f time, in secnds, that a replicatin transactin is at the Publisher waiting fr a Distributr t receive it, and has exceeded the warning threshld.

270 Causes f high distributin latency The mst cmmn cause f high distributin latency is when a transactin has a large amunt f cmmands. Once the transactin is cmplete, distributin latency decreases. The Replicatin view n the Services tab displays a graph with the nn-distributed cunt and the nn-distributed time. Graphs that trend upward may indicate a prblem that needs reslutin. Reduce distributin latency Yu can reduce distributin latency by: Reducing traffic n the publisher Limiting nn-replicatin related wrk by the publisher Increasing the netwrk bandwidth available t the publisher DTC Status alert The DTC Status alert prvides the status f the Distributed Transactin Crdinatr service. ESX CPU Usage (Percent) alert The ESX CPU Usage (Percent) alert indicates an unusually high amunt f CPU usage by the ESX server hsting the virtual machine n the mnitred SQL Server instance resides. The percentage f ESX server prcessr usage is listed under the cntrl. A high ESX server percentage culd indicate a large number f active client sessins. This alert is enabled by default and is available nly n instances hsted n virtual machines enabled fr VM mnitring. Reduce yur ESX CPU usage Cnsistently high ESX server prcessr usage culd indicate the need t: Reduce the number f SQL re-cmpilatins as they are CPU intensive. There are many reasns that an bject such as a stred prcedure is recmpiled and yu can remve mst f these reasns by careful cding. Make sure that all T-SQL statements (whether in a stred prcedure, trigger r ad hc statement) that reference bjects fully qualify the bject referenced. Fr example: SELECT * FROM Nrthwind.db Emplyees is a fully-qualified bject reference whereas SELECT * FROM Emplyees is a prly-qualified bject. Yu can reuse the executin plans f fully-qualified bjects "as is," whereas plans where yu either cannt reuse the nt fully-qualified bjects r, if they are reused, then they are subject t a highly restrictive COMPILE lck while SQL Server determines if all f the bjects referenced in the T-SQL cde have the same wners as the executin plan currently in cache. Bth f these situatins cnsume a significant amunt f CPU time. ESX Memry Swap Detected alert The ESX Memry Swap Detected alert indicates that memry is swapped t disk fr the ESX server hsting the virtual machine n which the mnitred SQL Server resides. This may be an indicatin f memry pressure n the ESX hst. This alert is disabled by default and is available nly n instances hsted n virtual machines that are enabled fr VM mnitring.

271 ESX Memry Usage (Percent) alert The ESX Memry Usage (Percent) alert prvides the percent f available memry used by the ESX server hsting the virtual machine n which the mnitred SQL Server resides. This alert is enabled by default and is available nly n instances hsted n virtual machines enabled fr VM mnitring. Reduce yur ESX memry usage If this value is regularly ver 80%, SQL Server needs mre memry r needs t use the memry it has mre efficiently. Cnsider implementing ne r mre f the fllwing slutins: If yur site makes use f extended stred prcedures that are infrequently called, then after calling them, issue a DBCC DLLNAME (FREE). Once an extended stred prcedure is called, it remains in memry until SQL Server is shut dwn even if it is never again called, which then wastes available memry. A DBCC dllname (FREE) releases that memry fr use by bth the prcedure cache and Data Pages, which has a significant psitive effect n bth the Prcedure Cache Hit Rati and the Buffer Cache Hit Rati. Execute SP_HELPEXTENDEDPROC t view the extended stred prcedures currently laded in memry by SQL Server. As each SQL Server lck requires 96 bytes f memry, the granting f lck space is dne at the expense f Data Pages and Prcedure Cache Pages. T maintain prper system perfrmance and thrughput, keep the number f lcks t a minimum by: Wherever pssible, using the (NOLOCK) ptimizer hint r SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED n select statements as this neither issues any shared lcks n the data it reads nr hnrs any exclusive lcks set by ther transactins. When updating all rws in a table with mre than 50 rws, using the TABLOCKX table hint. This table hint prevents SQL Server frm initially taking exclusive rw lcks, granting many f these lcks, and then escalating them t an exclusive table lck. When deleting all rws in any table, using the TRUNCATE TABLE statement instead f the DELETE statement as fewer lcks and ther system resurces are cnsumed in the prcess. Reducing the time that a lck is held by: Perfrming as much wrk as pssible befre the transactin perfrms its first update, delete, r insert. Fr example, add any necessary SELECT statements. Gruping all UPDATES, DELETES, and INSERTS as clsely as pssible within a transactin with as few SELECTS as pssible separating them. Cmmitting the transactin as sn as pssible after the final DML statement. Aviding any stps fr user input nce the transactin begins. Be sure t gather all user inputs befre the transactin starts. Allwing SQL Server t cnsume mre f the available memry, making sure that OS Paging des nt increase. Add mre physical memry (RAM) t the cmputer. If the cmputer is running multiple instances f SQL Server, then cnsider placing each instance n a separate physical cmputer. If the cmputer is running ther memry-intensive applicatins, such as IIS r Exchange, then cnsider mving each instance t a separate physical cmputer. Limit SQL Server cmputers t perfrming nly SQL Server wrk. Stp any unnecessary prgrams, such as allwing the cmputer t act as either a primary r backup dmain cntrller.

OS User Time (Percent) alert The OS User Time (Percent) alert prvides the percentage f CPU time spent by all prcesses executing in user mde n the SQL Server cmputer. Page Life Expectancy alert The Page Life Expectancy alert prvides that the number f secnds a page stays in the buffer pl withut references has fallen belw the warning level. A decline in page life expectancy can indicate an increase in the physical I/O requirements fr a user database. The rate decrease culd likely indicate that the memry taken away frm the buffer pl is frcing database pages t exit the buffer pl prematurely. Diagnse prblems with yur SQL Server instance Micrsft recmmends a minimum target fr page life expectancy f 300 secnds. This means that any given page in memry is kept in the buffer fr five minutes befre the buffer flushes the page t disk. A page life expectancy value f less than 300 secnds is indicative f either a memry prblem r inefficient query plans. Prcedure Cache Hit Rati (Percent) alert The Prcedure Cache Hit Rati (Percent) alert prvides the rati f prcedure cache hits t prcedure cache lkups.this value indicates the reuse f an executin plan frm memry as ppsed t a cmpilatin frm disk. Manage yur Prcedure Cache Hit Rati If yu regularly encunter values belw 80% nce SQL Server is actively running fr at least 30 minutes, then cnsider ne f the fllwing remedies: Make sure that all T-SQL statements (whether in a stred prcedure, trigger r ad hc statement) that reference bjects fully qualify the bject referenced. Fr example: SELECT * FROM Nrthwind.db Emplyees is a fully-qualified bject reference whereas SELECT * FROM Emplyees is a prly-qualified bject. Yu can reuse the executin plans f fully-qualified bjects "as is," whereas plans where yu either cannt reuse the nt fully-qualified bjects r, if they are reused, then they are subject t a highly restrictive COMPILE lck while SQL Server determines if all f the bjects referenced in the T-SQL cde have the same wners as the executin plan currently in cache. Bth f these situatins cnsume a significant amunt f CPU time. Add mre physical memry (RAM) t the cmputer.

281 If yur site makes use f extended stred prcedures that are nt called very ften, then after calling them, issue a DBCC DLLNAME (FREE). Once an extended stred prcedure is called, it remains in memry until SQL Server is shut dwn even if it is never called again! This is tremendusly wasteful in terms f available memry and a DBCC DLLNAME (FREE) releases that memry fr use by bth the prcedure cache as well as the Data Pages which has a significant psitive effect n bth the Prcedure Cache Hit Rati, as well as the Buffer Cache Hit Rati. In rder t view the extended stred prcedures currently laded in memry by SQL Server, execute SP_HELPEXTENDEDPROC.

Agent XPs are disabled when SQL Server Agent is stpped. Yu can re-enable Agent XPs thrugh the Server Cnfiguratin view and allw viewing f agent jb histries even when the agent is nt running. SQL Server CPU Usage (Percent) alert The SQL Server CPU Usage (Percent) alert indicates an unusually high amunt f CPU usage by SQL Server. The percentage f SQL Server prcessr usage is listed under the cntrl. A high SQL Server percentage culd indicate a large number f active client sessins. Reduce yur SQL Server CPU usage Cnsistently high SQL Server prcessr usage culd indicate the need t: Reduce the number f SQL re-cmpilatins as they are CPU intensive. There are many reasns that an bject such as a stred prcedure is recmpiled and yu can remve mst f these reasns by careful cding. Make sure that all T-SQL statements (whether in a stred prcedure, trigger r ad hc statement) that reference bjects fully qualify the bject referenced. Fr example: SELECT * FROM Nrthwind.db Emplyees is a fully-qualified bject reference whereas SELECT * FROM Emplyees is a prly-qualified bject. Yu can reuse the executin plans f fully-qualified bjects "as is," whereas plans where yu either cannt reuse the nt fully-qualified bjects r, if they are reused, then they are subject t a highly restrictive COMPILE lck while SQL Server determines if all f the bjects referenced in the T-SQL cde have the same wners as the executin plan currently in cache. Bth f these situatins cnsume a significant amunt f CPU time.

283 SQL Server Data Used (Percent) alert The SQL Server Data Used (Percent) alert indicates that yu have a high percentage f allcated database space in use. This alert is raised based n the database metrics cllectin interval specified in Server Prperties. Fr mre infrmatin, see Set general server ptins. Reduce yur SQL Server database space used Yu may need t increase the amunt f space allcated t databases, add disks t the cmputer hsting the instance, r mve databases t anther hst cmputer. If yu have autgrwth turned ff, this alert indicates that yu need t either allcate mre space fr databases r add mre disk space. If yu have autgrwth turned n and this alert is triggered ften, yu may need t adjust yur autgrwth settings t a higher percentage t imprve perfrmance. Cnstant grwth adjustments can degrade perfrmance. Fr SQL Server 2000 users, SQLdm may incrrectly reprt the file size. This issue ccurs when certain clumns in the sysindexes table becme inaccurate and prvide SQLdm with incrrect infrmatin regarding the number f rws and table size. T crrect this prblem, use the fllwing T-SQL syntax: DBCC UPDATEUSAGE ('database_name' ) GO We recmmend that yu execute this cmmand during nn-peak hurs as it is server intensive. SQL Server Errr Lg alert The SQL Server Errr Lg alert indicates that specific text appeared in the SQL Server lg. Yu can custmize which text triggers the alert. Yu can als custmize the severity f the alert based n the frequency f ccurrence. The default settings are: 11 - Warning 18 - Critical Use a size limit n yur SQL Server Errr lg SQLdm allws yu t limit the size f yur SQL Server Errr lg t help imprve respnse time and avid using unnecessary space n yur server. Fr additinal infrmatin and steps n setting this limit, see Cnfigure text and expressin alerts. SQL Server Lg Used (Percent) alert The SQL Server Lg Used (Percent) alert prvides the percentage f allcated disk space used by lgs n the SQL Server instance reached an alert threshld. Once the lg space is cmpletely filled, all updates t the event lg fail. This alert is raised based n the database metrics cllectin interval specified in Server Prperties.

Reduce yur SQL Server lg space used Yu can allcate mre disk space t the event lg, turn n the aut-grwth feature fr yur SQL Server lg, r add additinal disk space t the cmputer hsting yur SQL Server instance.

284 If autgrwth is turned ff fr yur lgs, this alert may indicate the need t either increase the allcated space fr lgs and/r add disk space t yur SQL Server envirnment. If autgrwth is turned n and yu are seeing this alert ften, yu may need t adjust yur autgrwth settings t a higher percentage t imprve degraded perfrmance resulting frm cnstant grwth adjustments. In certain cases, SQLdm may incrrectly reprt the file size. This issue ccurs when certain clumns in the 'sysindexes' table in SQL Server 2000 becme inaccurate and prvide SQLdm with incrrect infrmatin regarding the number f rws and table size. Use the fllwing T-SQL syntax t crrect this issue: DBCC UPDATEUSAGE ('database_name' ) GO We recmmend that yu execute this cmmand during nn-peak hurs as it is server intensive. SQL Server Memry Usage (Percent) alert The SQL Server Memry Usage (Percent) alert prvides the ttal server memry (Ttal Server Memry per sysperfinf) as a percent f ttal physical memry frm WMI. Reduce the percentage f memry used by SQL Server If this value is regularly ver 80%, SQL Server needs mre memry r needs t use the memry it has mre efficiently. Cnsider implementing ne r mre f the fllwing slutins: If yur site makes use f extended stred prcedures that are infrequently called, then after calling them, issue a DBCC DLLNAME (FREE). Once an extended stred prcedure is called, it remains in memry until SQL Server is shut dwn even if it is never again called, which then wastes available memry. A DBCC dllname (FREE) releases that memry fr use by bth the prcedure cache and Data Pages, which has a significant psitive effect n bth the Prcedure Cache Hit Rati and the Buffer Cache Hit Rati. Execute SP_HELPEXTENDEDPROC t view the extended stred prcedures currently laded in memry by SQL Server.

285 As each SQL Server lck requires 96 bytes f memry, the granting f lck space is dne at the expense f Data Pages and Prcedure Cache Pages. T maintain prper system perfrmance and thrughput, keep the number f lcks t a minimum by: Wherever pssible, using the (NOLOCK) ptimizer hint r SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED n select statements as this neither issues any shared lcks n the data it reads nr hnrs any exclusive lcks set by ther transactins. When updating all rws in a table with mre than 50 rws, using the TABLOCKX table hint. This table hint prevents SQL Server frm initially taking exclusive rw lcks, granting many f these lcks, and then escalating them t an exclusive table lck. When deleting all rws in any table, using the TRUNCATE TABLE statement instead f the DELETE statement as fewer lcks and ther system resurces are cnsumed in the prcess. Reducing the time that a lck is held by: Perfrming as much wrk as pssible befre the transactin perfrms its first update, delete, r insert. Fr example, add any necessary SELECT statements. Gruping all UPDATES, DELETES, and INSERTS as clsely as pssible within a transactin with as few SELECTS as pssible separating them. Cmmitting the transactin as sn as pssible after the final DML statement. Aviding any stps fr user input nce the transactin begins. Be sure t gather all user inputs befre the transactin starts. Allwing SQL Server t cnsume mre f the available memry, making sure that OS Paging des nt increase. Add mre physical memry (RAM) t the cmputer. If the cmputer is running multiple instances f SQL Server, then cnsider placing each instance n a separate physical cmputer. If the cmputer is running ther memry-intensive applicatins, such as IIS r Exchange, then cnsider mving each instance t a separate physical cmputer. Limit SQL Server cmputers t perfrming nly SQL Server wrk. Stp any unnecessary prgrams, such as allwing the cmputer t act as either a primary r backup dmain cntrller. SQL Server Respnse Time (Millisecnds) alert The SQL Server Respnse Time (Millisecnd) alert prvides the time (in millisecnds) SQL diagnstic manager currently needs t send a simple SQL cmmand t the SQL Server instance, have it prcessed, and receive the returned result set. High respnse times generally ccur when sessins are blcked r when either there is heavy netwrk traffic r netwrk prblems r when either the cmputer the SQLdm Repsitry r the cmputer the SQLdm Cnsle is hsted n is running slw due t varius prblems. Typically, this value shuld average belw 2000 ms fr a well tuned netwrk and server. Average values in excess f 2000 ms indicate either an excessively busy netwrk segment r a stressed SQL Server. Reduce yur SQL Server respnse time A cmmn cause t high respnse times is when sessins are being blcked. T fix this prblem, g t the Sessins tab and select the Blcking view t see if any sessins are blcking. Yu can then select the sessin and click either Trace Sessin t see what queries the sessin is creating and t see what is causing the blck, r Kill Sessin t stp it.

294 Understanding the Repsitry Database The SQLdm Repsitry cnsists f a SQL Server database named, by default, SQLdmRepsitry. This database cntains the fllwing infrmatin: Perfrmance metrics and statistics cllected frm yur mnitred SQL Server instances Cnfiguratin settings such as the cnnectin infrmatin fr the SQLdm Services and alert ntificatin rules Alert messages By default, the Repsitry database uses the simple recvery mdel. When this setting is enabled, SQL Server des nt maintain the transactin lgs fr the database. Likewise, any existing transactin lgs are nt included in backup data. If yur crprate plicies require transactin lg backups, cnsider changing the recvery mdel t full s that transactin lgs are maintained and archived. Understanding SQLdm Services SQLdm has tw centralized services, the Management Service and the Cllectin Service. These tw services reside n the same cmputer. The Management Service perfrms the fllwing primary functins: Prvides real-time data t the SQLdm Cnsle Receives histrical data frm the Cllectin Service fr strage in the Repsitry Raises alerts and sends alert ntificatins The Cllectin Service perfrms n-demand and scheduled cllectin frm the mnitred SQL Server instances. Recvery and Migratin Best Practices Verify the Cnfiguratin f the Target SQL Server When identifying the new SQL Server instance that yu want t hst the Repsitry and Services, make sure this instance meets r exceeds the prduct requirements as well as these specific requirements. Yu can dedicate the target instance t hsting the SQL diagnstic manager nly The target instance runs the same versin f SQL Server sftware that is currently running n the existing SQLdm cmputer Back up the Repsitry Database Use a tl such as Idera SQLsafe t perfrm a full backup f the Repsitry database. If yu changed the default recvery mdel t full, make sure yur backup includes all transactin lgs. Identify hw ften t backup the Repsitry database The frequency at which yu backup the Repsitry database depends n the fllwing factrs: Hw ften yur alert settings change Hw ften yur SQL Server envirnment changes as yu add new servers and databases r remve lder servers and database Hw much perfrmance data yu cllect in a given time perid Hw much risk yu are willing t incur

295 The backup frequency shuld reflect yur maintenance needs and allw yu t meet future mnitring requirements. Schedule rutine backups f the Repsitry database After yu identify the apprpriate backup frequency fr yur mnitring needs, use a tl such as Idera SQLsafe t schedule rutine backups f the Repsitry database. If yu changed the default recvery mdel t full, make sure yur backup includes all transactin lgs. Review disaster recvery guidelines Make sure yur recvery strategy includes plans t reinstate the riginal cmputer nce it is repaired. Cnsider the fllwing guidelines: T minimize data lss, plan t back up the Repsitry database n the temprary Repsitry cmputer immediately befre reinstating the riginal cmputer. Use the prcedures in this Technical Slutin t reinstate the Repsitry n the riginal cmputer and cnfigure the Management Service. T verify all cmpnents were reinstated crrectly, test yur implementatin. Uninstall the cmpnents yu previusly implemented n the temprary cmputer. Migrate yur SQLdm installatin The prcedures in this sectin detail the migratin steps fr mving bth the SQLdm Repsitry and the Services t a new cmputer. Fllw each sectin in rder fr a successful migratin. TIP SQLdm Applicatin security is nt maintained when yur SQLdm installatin is migrated t a new server. Fr mre infrmatin, see Use applicatin security t manage SQLdm. Get a New SQLdm License Key Because yu are migrating the Repsitry database t a different SQL Server instance, SQLdm requires a new license key. Yu can easily request a new license key by sending an t: licensing@idera.cm. T cmplete the request, make sure yu have the name f the SQL Server instance where yu plan t install the SQLdm Repsitry database. Restre the SQLdm Repsitry n the Target Cmputer Fr best results, use the fllwing guidelines migrate yur SQLdm Repsitry t the target cmputer: Perfrm a full restre Schedule the restre during ff-hurs, r times when yu expect the least cllectin activity T restre the Repsitry database: 1. Use SQL Server Enterprise Manager r Management Studi t clse any pen cnnectins t the Repsitry database. 2. Use SQL Server Enterprise Manager r Management Studi t take the Repsitry database ffline.
