AdventNet Inc. 3

5 Prerequisites For system resources monitoring (CPU, memory, disk etc.) in Windows, WMI must be installed. By default, this is available in Windows 2000 and higher versions. This needs to be installed separately in Windows NT. About WMI WMI refers to Windows Management Instrumentation. It is an implementation for Web-Based Enterprise Management (WBEM). It uses Common Information Model (CIM) industry standard to represent systems, applications, networks, devices, and other managed components in an enterprise environment. Through WMI, a client application can request information from managed object and send instructions to the managed object System Requirements The hardware and software requirements for the Systems and Applications Monitoring Feature Pack are same as that of AdventNet Web NMS. For more information on the supported system requirements, refer to Hardware Requirements and Software Requirements pages in the Installation Guide of Web NMS. Note: Database schema is currently available only for MySQL, Oracle, and Sybase. Support will be extended for other databases on a need basis. Systems and Applications Monitoring Components The components in the application monitoring framework are Application Discovery Engine: Discovers applications and their properties in a smart way. Status Polling Engine: Polls the applications for status, taking into account a number of parameters including connection time, data transfer rate, query time, and execution time to determine the availability and the state of an application. Threshold Mechanism: Triggers alarms or events when the status of an application changes. Data Collection Engine: Collects and stores application and server statistics on a periodic basis, enabling reporting and trend analysis. o Data collection for HostResource parameters such as CPU utilization, memory utilization, disk space, etc. can be done for Windows, Linux and Solaris machines. o Information about RollBack, SGA, Tablespace, etc. from an Oracle server can be collected. o It supports the collection of number of in octects & out octects (Traffic Utilization). Intuitive Runtime Administration GUI: Enables runtime configuration of applications discovery, status polling, data collection, adding new applications for discovery, etc. AdventNet Inc. 4

6 How It Works in Web NMS? The complete process of Application Management comprises application discovery, application status polling and application data collection. Application discovery begins after device discovery. The discovered applications are persisted in the database and continuous monitoring is done for the status and health of the applications 1. After the interfaces are discovered in a network, notifications are sent to the Application Discovery module. 2. Each discovered interface is tested for the presence of applications through predefined tests specified in <Web NMS Home>/conf/application/ApplicationDiscovery.xml file. 3. The discovered applications are continuously monitored for their status. The input for status polling of applications is got from <Web NMS Home>/conf/application/ ApplicationStatusPoll.xml file. 4. The severity information is captured as an Event or an Alert, based on the threshold specified, and updated in the database. 5. Data collection is performed to determine the health of the application being monitored. Data Collection is performed for applications and non-snmp nodes and the configurations are made in <Web NMS Home>/conf/application/ ApplicationDataCollection.xml file AdventNet Inc. 5

7 Application Monitoring in Web NMS RME Web NMS RME is the distributed edition of Web NMS. The Mediation Server is the distributed component. This edition, facilitates remote monitoring of network resources from a single console. Contact nms-support@adventnet.com for more details on Distributed Mediation Server. In Web NMS RME, the Distributed Mediation Server (DMS) performs the network facing functionality. Multiple DMS can be deployed in the remote sites depending on the scalability needs. Tests are defined to discover applications in the devices that are already discovered by the DMS. The DMS periodically updates the Central Server with the data like discovered InetService objects, application performance data etc.. AdventNet Inc. 6

9 Configuring Application Discovery Discovery Flow Diagram Viewing Discovered Services Configuring Applications Discovery Configuring Discovery Using Application Tests Configuring Discovery Using SNMP Properties Configuring Discovery Using Object Properties Configuring Discovery Using Mail Server Tests Adding a New Application at Runtime Deleting an Application (Resource Type) Following the discovery process of IP devices, checks are made to detect the presence of applications in the discovered IP devices. Various applications such as Web server, FTP server, NTP server, SMTP server, etc., can be discovered by Web NMS. The discovered applications are polled periodically to determine their status. Predefined tests are performed on the applications to know the status. Performance data are collected for Oracle applications (default implementation is provided) to monitor their health and performance. Discovery Flow Diagram The Application Discovery Module is registered as a Topo Observer and therefore receives notification when the IP devices are discovered and added to the database. The discovered IP devices are tested for the presence of applications based on specific predefined tests. The discovered applications, modeled as InetService Objects are added to the database. The InetService object is an extension of the class ManagedObject. Viewing Discovered Services When the feature pack is applied on Web NMS, the services or applications discovered in the network are displayed in the Web NMS client as Service Maps. All the services discovered are represented as separate nodes in the tree view. Each node displays the corresponding service map in the right-side panel. AdventNet Inc. 8

10 A symbol representing the service in a particular device, is displayed in the corresponding service map. The symbols also show the status of the service. The object-specific menu, i.e., Service-Menu appears on the menu bar, when an object symbol is selected from any one of the Services Maps. You can also access Service-Menu by doing a right-click operation on a selected object symbol in any of the Services Maps. The different operations listed in the Services-Menu are Menu Item Symbol Properties Managed Object Properties Node Edit Delete from DB Events and Alerts UnManage Operation Displays all the properties associated with a particular symbol on the Services Map. Displays the managed object properties for a particular object on the Services Map. The sub-menu items are Delete Symbol from Map and Add/Delete Property. The Delete Symbol from Map is used to delete a particular symbol from the Services Map. By clicking the Add/Delete Property item on the menu list, a dialog comes up, where you can configure the property to be added, deleted, or updated. You can delete the service object and its symbol from the database. The events and alerts corresponding to the selected object are displayed. You can unmanage a particular service by using this option. Configuring Application Discovery You can configure the discovery of a specific application based on, Application Test - Application Test is used to discover a particular application. The supported applications have predefined tests. For example, applications such as Web server, FTP server, have predefined tests called Web-Test and Ftp-Test respectively. These tests have certain common arguments that are configurable. Object Property Test - Application discovery can be triggered based on some managed object properties. The testproperty can be any ManagedObject property. The expectedvalue is given based on the testproperty specified and any string value can be specified. The testcondition indicates the relationship between the testproperty and the expectedvalue. By default, if the relationship is not specified, it is taken as contains SNMP Property Test - This test follows the STRING-COMPARE or NUMERIC-COMPARE condition based on the OID that is being queried. The specific OID that has to be queried is given in testproperty. Mail Server Test - This test checks the SMTP port and POP port at the default port numbers 25 and 110 respectively, and discovers the services running at these ports as MAIL servers. Configuring Discovery Using Application Test For instance, Web server is one of the standard applications discovered and monitored. The application test will be performed only at the default port, that is Port No. 80. If you want applications running in some other port numbers also to be discovered as Web servers, then, you can provide multiple port numbers as a comma separated list for the Port parameter.

16 12. Click Finish to exit the wizard 13. Click Apply. Result: This will discover any Web NMS server in the network as another application. Since we have provided the URL-Discovery class, it will be discovered as a Web Server application. Note: You must associate a menu for the newly added application. It can be done from the Map UI Settings at runtime. The menu that you must associate to the application is ResourceMenu. When a new resource type is added from this Runtime Administration UI, then, application discovery will be initiated for all the objects that are already discovered. When you add a new application for discovery, you must configure status polling for it. Automatic status polling for a newly added application will not take place. Deleting an Application (Resource Type) You can delete an application that you do not want to be monitored by Web NMS (or by the DMS in RME edition). This will delete the application from the Service Map, application Status Polling Configuration UI and wherever the references to the application exists. To delete an application, 1. From the Runtime Application Discovery UI, select the required application from the list. 2. Click the delete icon at the bottom of the column. The application is deleted. AdventNet Inc. 15

17 Managing Multiple Instances of an Application It is possible that more than one instance of an application is running in the same machine. All the instances must be discovered and monitored. Web NMS allows multiple instances discovery. You can manage and monitor multiple instances of an application as explained below: Configuring Multiple Instances Discovery To discover multiple instances of an application 1. Go to Tools-->Runtime Administration-->Application-->Application Discovery. 2. The applications are listed on the left. Select the application whose instances you want to discover. 3. The test type is displayed on the right. Click Modify. 4. In the wizard that pops up, click Next. 5. The test properties are displayed. In the Port Number field, enter the port numbers as a comma separated list. 6. Click Finish to exit the wizard. 7. Now, click the Advanced Properties button. The Advanced Properties dialog pops up. 8. Select the check box that corresponds to Discover All Instances. 9. Click OK. 10. Click Apply. The instances running in the specified ports are discovered. AdventNet Inc. 16

18 Performing On-demand Application Discovery You can discover a particular application in a device on demand. That is, an application may not be up and running in a particular device during discovery. If the application is started after some time, it will not be discovered unless configured. To discover such applications in a device, a device specific menu is provided. See the example given below. To discover a particular application in a device, 1. From the Client tree in the UI, select the node Network Database --> Nodes. The list of nodes in the network(s) will be displayed. 2. From this list, select the node (device) in which you want to discover a particular application that is not discovered already. For instance, let us assume that you want to discover FTP service in a Windows device. 3. Right-click the selected node and click the menu Node (or SNMP Node) --> Discover Application. 4. The corresponding UI pops up. The list of supported applications that are not discovered in that device, is displayed. From this list, select the required application. Example: FTP Server 5. If there are multiple interfaces, select the required interface from the corresponding combo box. 6. Click OK. The selected application will be discovered if it is running. AdventNet Inc. 17

19 Using Thresholds Configuring Thresholds Applying Thresholds on Applications AdventNet Inc. 18

20 Configuring Thresholds Overview Threshold Types Modifying Thresholds Adding New Thresholds Overview Thresholds are baselines established to monitor data collection and application status polling. If collected data goes beyond the Threshold value, it indicates that the collected value is not a recommended value which may deteriorate network performance. Thresholds are applied on network resources to calculate their performance. The thresholds are applied based on the response time, connection time, transfer rate, login time etc, of a network resource. It is also applied on the collected value in Oracle data collection. There are a set of predefined thresholds, say Th1 to Th8, Orcl1, and Host1.. If the response time exceeds a specified threshold value, a corresponding severity status is assigned to the device and an event for that severity is generated. The Warning, Major, Minor, and Critical values, both for threshold and rearm, are set by default. You can configure the predefined thresholds, or add new threshold levels from the Runtime Administration UI. Default Severity, Threshold Value, and Rearm value are displayed in the client. Note: These thresholds are defined in ThresholdData.xml located in <product home>/conf/application directory. These cannot be applied for SNMP data collection (polling configuration). The thresholds for the same are defined in Threshold.conf located in <product home>/conf directory. AdventNet Inc. 19

21 Threshold Types There are two threshold types, namely Increasing Threshold: An example for Increasing Threshold type can be response time test. That is, Web NMS checks for the response time of a particular resource. If the resource takes more time of respond to the Web NMS server, the test is considered to have failed. Based on the Threshold and Rearm values set for Warning to Critical, the test result will be assigned a status. Example: For the Web NMS server to assign a warning status for the result of a test, the response time must be more than the Warning threshold value 300 seconds (but less than the Critical threshold value 600 seconds, because if it crosses this value, status will be assigned critical). Decreasing Threshold: An example of Decreasing Threshold type can be bandwidth test. The Web NMS server conducts a test for bandwidth for transmission. If the bandwidth available is found to be less than a particular value, then the test is considered failed. Based on the Threshold and Rearm values set for Warning to Critical, the test result will be assigned a status. In this case, the threshold values for Warning status will be the highest and for Critical it will be the least of all. Modifying Thresholds To modify the predefined thresholds 1. From the client menu bar, select Tools-->Runtime Administration-->Application -- >Threshold>. The left panel displays the different threshold levels. 2. Select any threshold node from the list of thresholds on the left panel. For instance, Th1 node. 3. In the right panel, select the Threshold type as Increasing. 4. From the Severity column, select any one severity and change the default threshold and rearm value. 5. For instance, select Warning severity, enter the threshold value as 30 and rearm value as Click Apply. Result The new threshold and rearm value are applied for Warning severity. That is, a warning event is generated if the response time crosses 30 seconds and the rearm value for the same will be 20 seconds. You will see a Warning severity being generated for a resource if the response time crosses 30 seconds. You can see a message to this effect in the client in the message field. Adding New Thresholds To add or define new thresholds 1. From the menu bar, select Tools-->Runtime Administration-->Application -->Threshold. The left panel displays the different threshold levels. 2. Click the button at the bottom of the list. 3. A new threshold is added to the list as NewName1. 4. Rename the added threshold by double-clicking the particular node. It becomes editable. Rename and press Enter. AdventNet Inc. 20

22 5. By default, the new threshold node will now be highlighted and the corresponding configuration parameters will be displayed on the right side. 6. Select the threshold type as either increasing or decreasing depending on the threshold you want to define. 7. Click the button on the right. 8. Select the required severity from the combo box and configure the threshold and rearm value (double-click the fields to edit the default values). 9. After you add all the required severity levels with the corresponding values, click Apply. Result The new threshold will be applied on the response time of a network resource. Note: Rearm Value: The rearm value is used to prevent assigning of same status to a resource every time it is tested. If a resource is assigned Warning state as it has crossed the Warning threshold value, it will be assigned a Clear state only if it goes below the Warning rearm value in the subsequent tests. AdventNet Inc. 21

23 Applying Thresholds on System Resources Applying Thresholds During Application Status Polling Applying Thresholds During Oracle Data Collection Applying Thresholds During Host Resources Data Collection There is a need to manage and monitor various applications based on priority. That is, some missioncritical applications may require constant check. The availability of the service may be crucial. According to the priority of the services required, you can define thresholds. For instance, you can define a threshold on applying which an event is generated after the specific response time, and that can be 300 seconds or even seconds. Thresholds can be applied during status polling and data collection of the applications. Applying Thresholds During Application Status Polling You can apply thresholds on the discovered applications that are scheduled for status polling. Events will be generated during status polling of the applications, based on the defined thresholds. 1. From the menu bar, select Tools --> Runtime Administration. The Runtime UI opens. 2. Select Application -->Application Status Polling. The applications scheduled for status polling are listed in the left column. 3. Select any application for which you want to associate a threshold. Example: MYSQL-DBserver. The status polling test properties are displayed on the right. 4. Click the Advanced button to configure the parameter on which you want to apply threshold. A dialog pops up. Select the required parameter from ApplyThresholdOver combo-box. For this application, the parameter available is responsetime. (For database applications, you can even configure the required driver name and the url). 5. From the properties list, select the Value field adjacent to thresholdname property. 6. Select the required threshold from the combo box. Example: Th8 7. Select the check-box corresponding to Apply changes to discovered nodes option. This will apply the changed threshold to the discovered applications during subsequent status polls. 8. Click Apply. AdventNet Inc. 22

24 The selected threshold is applied for the already discovered MYSQL-DB-servers and the newly discovered ones during the subsequent status polls. Applying Thresholds During Oracle Data Collection You can configure thresholds for the monitored Oracle parameters from the Runtime UI. Events will be generated during data collection for the parameters, based on the thresholds defined. 1. From the menu bar, select Tools --> Runtime Administration. The Runtime UI opens. 2. Select Application -->Application Data Collection --> Oracle Configuration. 3. Select the specific Oracle table from the displayed list, for which you want to configure threshold. Example: SESSIONINFO 4. From the Select Threshold column, select the required threshold for the listed parameters. Example Parameter:cursors Threshold: Orcl1 The details of the selected threshold are displayed in the Threshold Details column below. 5. Click Apply. Events will be generated by applying the new thresholds configured. Thresholds are applied on the collected data. Applying Thresholds During Host Resources Data Collection You can configure thresholds for host resource data from the from the Runtime UI. Configured thresholds are applied on the collected host resource data, and events are generated based on it. To know the steps to configure a parser, see Configuring System Resources and Parsers. To configure threshold for host resource data, 1. From the Host Resource RTA, select a parser under a monitored system parameter. Example:SwapMemUtilization under Memory Utilization. The corresponding parser properties are displayed. AdventNet Inc. 23

25 2. Click Modify. 3. Click Next >Next in the subsequent configuration screens that pop up. 4. In the Event Generation column in the configuration screen, select Threshold from Compare With combo-box. 5. From the Select Threshold combo-box, select the required threshold. Example Host1 6. Click Finish. 7. Click Apply. The new threshold will be applied on the host resource data collected for the specific parameter (in this example, for SwapMemUtilization in Memory Utilization). Events are generated based on the threshold applied. AdventNet Inc. 24

26 Polling Applications for Status Polling Applications to Determine Their Status Understanding and Configuring Test Properties AdventNet Inc. 25

27 Configuring Application Status Polling Overview Configuring Predefined Tests for Application Status Polling Adding a New Application and Configuring a Test for It Overview The applications that have been discovered are continuously monitored for their status and optimal functioning through the Status Polling Framework. The discovered applications are scheduled for status polling. Predefined tests are available to perform status polling of these applications. You can configure the existing properties of a particular test for an application. You can add, modify, delete, cut, and copy an application using the right-click menu available. Configuring Predefined Tests for Application Status Polling As mentioned earlier, predefined tests are available for the support applications. The test properties have default values. You can configure the property values to meet your specific requirement. For instance, let us assume you want to poll the status of a Web-server once in 30 minutes, instead of polling it every 5 minutes. configure a different user name and password since the web page requires authentication traverse three links (depth) from that web page So, you need to change the default values for the corresponding properties. The steps are, 1. Select Web-server application from the list. The predefined test for this application is URL- Test. The test properties are displayed in the 'attributes' column. 2. Provide the value for depth field as Provide the value for the testinterval field as Provide the required user name in the relevant field. Example:test-advent 5. Provide the password for the user. Example:advent 6. Select the check-box corresponding to Apply changes to existing nodes (this option enables you the apply the changes made in the test to the nodes that are already discovered. If this option is not selected, the changes will be applied only to the applications discovered thereafter). 7. Click Apply. AdventNet Inc. 26

28 The URL-Test will be performed on the application with the specified properties. Adding a New Application and Configuring a Test for It It is mandatory that the new application must be first added and configured for discovery, before adding the same for configuring status polling. Refer Configuring Application Discovery for details. 1. From the menu bar, select Tools --> Runtime Administration --> Application --> Application Status Polling. 2. Select any node from the left panel containing the list of applications. 3. Click button at the bottom to add the new application for which status polling must be performed. 4. A new application is added in the name NewName1. AdventNet Inc. 27

29 5. Double-click the new application node and enter the required application name. 6. From the right panel, select the type of test to be performed from the corresponding combobox.

30 Understanding and Configuring Test Properties Predefined Test Names and Their Descriptions Configurable Attributes of Predefined Tests Predefined Test Names and Their Descriptions Test Name Description The URL Test is used to determine the status of the Web server. Monitoring of the Web server can include checking for availability of service loading time of the page URL-Test efficient functioning of the links efficiency of navigation, etc The URL Test tests the Http connectivity, data transfer rate, and time taken to connect to a URL. Test Class name: com.adventnet.nms.spp.application.statuspoll.urltest For scheduling a DNS server for status polling, ensure the application has been scheduled for discovery in the ApplicationDiscovery.xml file and uncomment the entires for DNS server in the ApplicationStatusPoll.xml file. DNS-Test The DNS test is performed for status polling of the DNS server. For a given domain name server and the lookupaddress, the response time is calculated. Tests are done to check if the expected value is returned for a given domain name. Test Class name: com.adventnet.nms.spp.application.statuspoll.dnstest Different mail servers, such as SMTP server, POP server, IMAP server and MAIL server can be continuously monitored and their status determined using this test. SMTP- Test POP-Test Imap-Test MAIL- TEST In SMTP test, checks are made to ascertain if the target given is an SMTP server and the performance of the SMTP server is calculated in terms of its response time. Test Class name: com.adventnet.nms.spp.application.statuspoll.smtptest The test used for status polling of POP3 server is POP3Test. In this test, it is checked if the target is a POP3 server and its performance is calculated in terms of the response time. Test Class name: com.adventnet.nms.spp.application.statuspoll.pop3test USER TEST is used for testing the IMAP server. In USER TEST, you can specify the Test Case based on which the status polling has to be done. For monitoring the IMAP server, two test cases are configured. Test Class name: com.adventnet.nms.spp.application.statuspoll.imaptest The test used for monitoring this application is the MailTest. This test is used to check if the server connected is a mail server and its performance is calculated in terms of the response time.

31 Test Name Description A database server acts as a storehouse of information which is in the form of tables, structured via databases. The efficiency of this server lies in its ability to respond promptly to the structured queries made by users to retrieve data from the tables present SQLin it. Default support is available for monitoring MSSQL DB server and MYSQL DB QUERY server. FTP- TEST PING- TEST DHCP- TEST NTP- TEST Test Class name: com.adventnet.nms.spp.application.statuspoll.sqlquerytest The performance of the FTP service is determined by the Connection Time, Login Time, and Transfer Rate. These parameters need to be checked for monitoring the FTP service. Test Class name: com.adventnet.nms.spp.application.statuspoll.ftptest The printers that have been discovered on the network can be status polled by using the PING command. In this test, a ping command is sent to the resource and is checked for its status. Test Class name: com.adventnet.nms.spp.application.statuspoll.pingtest The test used for monitoring the DHCP server is DHCP. In this test, the response time of the DHCP server is monitored. Based on the response time the status of the DHCP server is updated. Test Class name: com.adventnet.nms.spp.application.statuspoll.dhcptest The test used for monitoring the NTP server is the NtpTest. It creates an NTP packet and is sent to the NTP resource and the performance of the server is calculated in terms of its response to the NTP packet. Since the tests configured for different applications cannot be used for testing the NTP server, USER TEST is used and the testname is NTP.

35 Need for Oracle Applications Monitoring Overview Scope Overview Oracle Performance monitoring makes DBA/System Administrator's job easier. The databases are getting much larger and very complex that require tuning which necessitates a readily available userbuilt interface tool to monitor the administration tasks. The DBA must have regular database information to manage mission-critical databases and identify technical problems without any bottleneck. The monitoring tools give us an insight into the flow of processes within an Oracle instance which helps us identify database activity at any given time. It identifies bottlenecks with extensive drill-down capabilities in the form of alerts and events. The drill-downs give us detailed information about the specific problems. The database must be monitored in a fashion that takes its specific structure and usage into account. Scope The scope of monitoring involves defining A set of metrics that gauge the health of the database. A systematic method for making those measurements and determining trends The common problem areas include Running out of free space in a tablespace Insufficient space for temporary segments Rollback segments that have reached their maximum extension Fragmentation of data segments and free space Improperly sized System Global Areas (SGA) An effective database monitoring system must detect unacceptable values for each of the areas mentioned above. Note: If Oracle database servers are to be monitored, ensure that classesxx.zip (database driver for Oracle) is installed in your systems and the classpath for the same has to be set in the startnms.bat /sh file located in <Product Home>/bin directory.

40 Need for Monitoring Host Resources What Are Host Resources? Need for Monitoring the Resources What Are Host Resources? Host Resources are system performance components such as CPU, Memory, Disk, System Load, etc. Applying the Systems and Applications Monitoring feature pack enables host resources monitoring functionality using Web NMS. Need for Monitoring the Resources Network-level management, maintaining the status, and connectivity of the network is crucial in large/small enterprises, service providers, etc. It is of prime importance to know the status of the machines in the network, how overloaded they are and how efficiently they are utilized, to enable necessary corrective administrative measures on the identified overloaded/poorly performing systems. System-level management involves a lot of manual intervention, human resources, and administrative tasks to be performed. To achieve such goals and to ease the process of configuration management of Hosts, we provide a system-level monitoring/management functionality called Host Resource Monitoring. An effective runtime administration GUI is provided for configuring new system parameters to be monitored, or to modify existing ones. Host Resource Monitoring meets the following needs: This is of extensive use to system administrators who want to track all Hosts in their Domain from a single console. Servers whose downtime is not acceptable/affordable. Critical Systems, whose performances are related to the functionality of the other systems in the network. Managing these resources pro-actively, before occurrence of any fault, is the main scope of Host Resource Monitoring. AdventNet Inc. 39
