11 Chapter 1. Introduction New in this release Background information The IBM Tivoli Monitoring Infrastructure Management Dashboards is a web-based application that runs in the Dashboard Application Services Hub. The Infrastructure Management Dashboards for Servers give the overall status of the service areas in your managed network, with links from the highest level overview to in-depth metrics on individual managed systems. Review the latest enhancements to the Infrastructure Management Dashboards for Servers since the release of Version 6.3. Managed system dashboard tabs: Properties, CPU, Memory, Disk, Network To broaden the reporting provided in the Overview and Process tabs for each managed system, several tabs have been added: v v v v Properties tab showing the status, version, and other configuration information about the managed system and the operating system that it runs on. CPU tab showing key values about each processor on the managed system. Memory tab showing key values on the managed system that you can use to assess memory usage and detect bottlenecks. Disk tab showing key values related to the disks on the managed system. v Network tab showing metrics to help you determine the sources of network activity and identify trends on the managed system. Time selector for showing historical data samples The situation event results dashboard Details tab has a time selector bar for setting a time range of data samples before or after the event time that you can compare with the value or values that triggered the event. The CPU, Memory, Disk, and Network tabs of the managed system dashboard have a time selector bar showing the current time span setting, such as Real Time or Real Time - Last 2 Hour(s). You can select different time periods or set a custom time span to report. After you change the dashboard from showing real time values to showing a time range, a set of line charts is presented to show historical values. If a table of real time metrics is also displayed, you can control which rows to include. For example, in the Disk tab, a line is plotted for the aggregate of disks on the managed system. You can select individual disks to include in the line chart. Use the Infrastructure Management Dashboards for Servers to assess the event and system status of your managed network that is filtered by your area of responsibility. The information in the Server Dashboards ranges from a high-level overview of all managed system groups, to more detailed dashboards with key performance information about the selected group, managed system, or situation event.

12 Server Dashboards and the Tivoli Enterprise Portal After your administrator configures a connection to the dashboard data provider, you can view the Server Dashboards. Situation event status information and operating system metrics that are obtained from your Tivoli Monitoring environment are displayed in the Server Dashboards. Use the Tivoli Enterprise Portal or the command-line interface to complete tasks, such as those that affect how the Server Dashboards are displayed: creating managed system groups for the Managed System Groups dashboards, creating situations for generating situation events that display in the Situation event results dashboard; and historical data configuration for the managed system dashboard CPU, Disk, Memory, and Network tabs. You can launch the Tivoli Enterprise Portal from the Server Dashboards. See Creating a connection to the IBM Tivoli Monitoring dashboard data provider in the IBM Tivoli Monitoring Administrator's Guide for the procedure to connect to the dashboard data provider. See the Tivoli Enterprise Portal User's Guide ( v61r1/topic/com.ibm.itm.doc_6.3fp2/ic/landing_tepuser.htm) and IBM Tivoli Monitoring Command Reference ( tivihelp/v61r1/topic/com.ibm.itm.doc_6.3fp2/ic/landing_cmdref.htm) for details about the Tivoli Enterprise Portal and the CLI. Managed system groups The Managed System Groups dashboard is the home dashboard, and shows data consolidated from every managed system in the managed system groups that you have defined and that are predefined for your monitoring products. Managed system groups are named lists of systems where Tivoli Enterprise Monitoring Agents are installed and are typically organized by function or line of business. Every Tivoli Monitoring product has at least one predefined managed system group, indicated by an asterisk at the beginning of the list name, such as *NT_SYSTEM for the Windows OS agent. You can create custom managed system groups in the Tivoli Enterprise Portal client or the command-line interface. (See Managed system groups in the Tivoli Enterprise Portal User's Guide.) Server Dashboards In the Dashboard Application Services Hub console, click System Status and Health > Server Dashboards to open the home dashboard. Managed System Groups Overview shows the situation event status of all the managed system groups in your managed network. From there, you can link to a tabbed dashboard with event information about the chosen managed system group, and link to detailed metrics for an individual managed system or situation event. You can also link to the detailed metrics from the Situation Events dashboard. The Server Dashboards are all predefined and cannot be edited. You can, however, change the time span reported in the situation event results and adjust the display of tables and charts Note: In bi-directional language locales, the charts do not have full bi-directional support: the chart elements are not mirrored, but the legend and labels are. Dashboard navigation Along the top of every dashboard, is the path to the current dashboard. Click one of the hypertext links in the path to return to a previous 2 IBM Tivoli Monitoring: Infrastructure Management Dashboards for Servers Reference

13 dashboard. On the left side of the page are resource navigation icons ( and ) that you can click to return to the home dashboard or to open the Situation Events dashboard. Managed System Groups dashboard This is the home servers dashboard gives a high-level overview of the open situation events and their severity for every managed system group associated with the hub Tivoli Enterprise Monitoring Server. The top view shows the managed system groups as icons. Click Switch View to toggle between the icon view and a table view of the situations events that are open for each managed system group. From either view, you can link to a dashboard with metrics from the selected managed system group. From the table view, you can also link to specific event details or to key metrics on the managed system. The bar charts along the bottom of the dashboard show a total count of the situation events in the managed network, one bar for each severity; the most critical managed system groups, one bar for each group and ordered by those with the most severity; and the situation event count for each monitoring agent type. For more information, see Managed System Groups dashboard on page 8. Managed system group dashboard From the Managed System Groups Overview dashboard, select a managed system group such a *LINUX_SYSTEM to link to a tabbed page of situation status and key operating system metrics for each of the managed systems in the group. For more information, see Managed system group dashboard on page 9. Managed system dashboard From the managed system group dashboard Overview tab and from the Situation Events tables, you can click a managed system name to open a dashboard of detailed metrics and event listings for the selected managed system. The managed system dashboard has several tabs with charts and tables that report key performance metrics in real time: Overview, Properties, CPU, Memory, Disk, Network, and Process. In the tabs that can display historical data, you have a time selector bar for changing the time span. After you select a time span, the page layout changes to show historical line charts. Some of the tabs include a table (or tables) with real time metrics to compare with the historical data in the line charts. For more information, see Linux managed system dashboard on page 15, UNIX managed system dashboard on page 24, and Windows managed system dashboard on page 32. Situation Events dashboard The Situation Events dashboard provides an alternate overview. Here you see a table of the situation event status from all the managed systems that report to the hub monitoring server. For more information, see Situation Events dashboard on page 11. You can see a filtered version of the same table in the Situation Events tab of the managed system group dashboard and the Chapter 1. Introduction 3

14 managed system dashboard. For more information, see Displaying situation event results on page 7. Situation event results dashboard The event results dashboard gives you a chart for every expression in the formula, plotted with two hours of data samples before the event and up to two hours after event. You can extend this range by as much time as you have historical data for, and read the charts to help identify trends and data spikes over time. The dashboard is available by clicking a situation event from the Situation Events table. For more information, see Situation event results dashboard on page 12. Returning to a previously viewed dashboard or exiting the web application Use the resource navigation icons ( and ) to go back to a previous dashboard rather than your browser's Back button. Dashboards are treated as a single portal page; thus, using the browser's Back button exits the application. After you exit the console with the logout option, by closing the browser window, or by clicking the browser's Close button or Back button, it might take a moment for proper shutdown. Do not repeatedly click the Close or Back button or the browser might become unresponsive. Tip: The Infrastructure Management Dashboards for Servers are designed for a screen resolution of 1280 x 1024 pixels or higher. For the best fit of dashboard elements, adjust your browser window to 1280 x 1024 pixels or higher. Role-based authorization policy When your Dashboard Application Services Hub configuration includes the Authorization Policy Server, the administrator can control user access to managed systems groups and individual managed systems. It is possible for the roles that are assigned to your user ID to have a mix of permissions that make it possible, for example, to see the dashboard for a particular managed system but not the situation events for that managed system type. In this case, the dashboard is displayed but not the situation event data. If you open the Server Dashboards and get empty charts and tables but no error messages, it might be because you are not authorized to see any data. Supported monitoring agents In this release of Tivoli Monitoring, the supported monitoring agents are the OS agents for Linux, UNIX, and Windows Version or later. If the managed system group that you are viewing includes managed system types that are not supported, the situation event results and metrics for those managed systems are excluded from the consolidated views of the managed system group dashboards and the situation events dashboards. However, they are included in the situation event counts, such as. If you open the situation event results dashboard for an unsupported monitoring agent, the Details and Advice tabs are empty except for the formula. Actions All Server Dashboards have an Actions menu from which you can select options to launch into the Tivoli Enterprise Portal, copy the URL of the 4 IBM Tivoli Monitoring: Infrastructure Management Dashboards for Servers Reference

For more information, see Copying the URL on page 48, Launching to the Tivoli Enterprise Portal on page 48, and Setting a trace on page 49. Dashboard Health Checks You can open the Dashboard Health Checks to run a health check of your infrastructure management dashboard components and report their status: Click System Status and Health > Dashboard Health Checks. The connection to the dashboard data provider on the Tivoli Enterprise Portal Server is checked and the results are shown in the Tivoli Monitoring table. The Virtual Infrastructure Monitoring table shows the results of similar health checks for the installed dashboards, such as the Dashboard for VMware. If the table is empty, the monitoring agent is not available on the Dashboard Application Services Hub. For more information, see Dashboard Health Checks ( com.ibm.tivoli.itmvs.doc_7.2/dashboards_reports/ db_vmware_using_healthcheckdb.html) in the IBM SmartCloud Monitoring information center.

Related concepts: Background information on page 1 Related reference: Page layout and controls on page 43 Managed System Groups dashboard on page 8 Situation event results dashboard Open the event dashboard for a situation to see the value or values that triggered the event and a range of data samples before and after the event. You can link to the dashboard by clicking the hypertext link in the Situation Name column of the Situation Events table, which is displayed in the Situation Events dashboard, the Situation Events tab of the managed system group dashboard, and the Overview tab of the managed system dashboard. Details tab Line chart One line chart is displayed for each numeric attribute in the situation formula. The data sample, or samples if the situation has multiple expressions, that triggered the event is shown, along with up to two hours of historical data before and after the event. The solid line plots the values of the attribute that triggered the event. The gray area begins at the situation interval when the threshold was breached and the event was opened. In the following example, the situation is true if the free disk space falls below 5%. We can see that the value falls below 5% a few minutes before the event is opened. The event occurrence takes place after the threshold was exceeded rather than at the same time because the historical data sampling is recorded more frequently than the sampled situation interval, which, in this case, is 15 minutes. The gray area continues on the time line while the condition remains true. 12 IBM Tivoli Monitoring: Infrastructure Management Dashboards for Servers Reference

23 The broken line along the X-axis marks the threshold that was set. If you have multiple expressions for the same attribute, multiple threshold lines are displayed. Clear the Show Thresholds check box if you want to remove the threshold lines from the chart. Viewing a range of data samples helps you to identify trending behavior. You can use the time selector to show longer periods of time before the event. Click the time selector bar (such as Last 2 Hour(s) Before Event Occurrence ) and click one of the options to increase the time that is shown before the event to 4, 8, or 12 hours; 1 day; 1 week; or to set a custom time range. For details, see Select Time Range on page 46. Table Note: No historical data samples are plotted if historical collection was not configured for the attribute group or if the collection was only recently configured. For example, you must wait at least two hours after you configure a new historical collection before you can expect to see historical values if data samples are saved only once per hour. For more information about historical data collection, see Creating a historical collection in the Tivoli Enterprise Portal User's Guide or the tacmd commands for history in the IBM Tivoli Monitoring Command Reference ( infocenter/tivihelp/v61r1/topic/com.ibm.itm.doc_6.3fp2/ic/ landing_cmdref.htm). Text values (such as missing processes) cannot be plotted in a chart. Below the formula is a table with the data sample that triggered the event. For events that include a current data sample, you have an Expand icon in the Server Name column that you can click to see the current results. If the table has multiple rows, you can filter or move through the table pages as described in Table controls on page 46. The first column shows the color that corresponds to the plot points for that attribute in the line chart. You can clear the check box to remove the line from the chart. Advice tab The Advice tab shows any expert advice that was written for the situation. If you created a situation in the Tivoli Enterprise Portal or Tivoli Monitoring command-line interface with advice that includes a link to a file, the URL is displayed. For more information, see Writing expert advice in the Tivoli Enterprise Portal User's Guide and the tacmd commands for situations in the IBM Tivoli Monitoring Command Reference ( Chapter 2.

25 Chapter 3. Managed system dashboards Select a managed system dashboard from the Managed System Group dashboard or from the Situation Events dashboard to open a tabbed dashboard with metrics from the managed system. Linux managed system dashboard Use the Linux managed system dashboard to get a status overview of situation events and to see system details, both current and historical. After you select the Linux OS managed system link from the Managed System Group dashboard or from the Situation Events dashboard's Source column, the Linux managed system dashboard is displayed. The dashboard plots metrics from the selected managed system in the following tabs: Overview presents the top five contributors to CPU, memory, disk, and network utilization, and a Situations Events table of open events Properties on page 16 shows status and configuration information about the operating system and managed system CPU on page 16 presents key values related to each processor Memory on page 18 presents key values about physical and virtual memory consumption and distribution Disk on page 19 shows disk activity and other key values about the Linux disks Network on page 21 presents key values related to network utilization Process on page 23 shows current process utilization information Each tab has charts and tables to help you research and understand problem areas. Look for patterns and trends in the values. For example, are values consistently high, or do they spike at random or specific intervals? For more information about how to manipulate the dashboards, what actions you can take, and the metrics shown, see the following topics: Page layout and controls on page 43 Table controls on page 46 Attributes topics in the IBM Tivoli Monitoring Linux OS Agent Installation and Configuration Guide ( com.ibm.itm.doc_6.3fp2/oslinux/linuxosagent_user.htm) Overview Use the Overview tab to examine the open situation events on the managed system and to get a quick reporting of the most significant metrics in bar charts. If you can see a pattern across the Top 5 metrics or one that you would like to investigate further, click the corresponding tab for detailed information. CPU Utilization (%) - Top 5 plots a bar for each of the five processes that use the highest percentage of CPU on the selected managed system. If CPU usage is high, it is likely that one or more of these processes is responsible. (This is a default view.) Copyright IBM Corp

26 Memory Utilization (%) - Top 5 plots a bar for each of the five processes that use the highest percentage of memory on the selected managed system. (This is a default view.) Disk Space Utilization (%) - Top 5 plots a bar of the five file systems where files are using the largest percentage of the space that is allocated to the file system. If disk allocation is high, consider increasing the allocated space or moving files. Situation Event Count by Severity plots a bar for each of the following event severities to show the total number of situation events that are open for the managed system: Fatal, Critical, Warning, Harmless, Informational, and Unknown. Network Utilization (Packets/sec) - Top 5 plots a bar for the five network interface adapters, including the Aggregate, that send and receive the most packets per second. From this stacked bar chart, you can see where the most traffic occurs and how efficient the load balancing is. Situation Events that have been opened for the managed system and their status are listed in this table, sorted by the events with the highest severity first, and refreshed as new events arrive. For a description of the toolbar and the actions you can take in this view, see Situation Events dashboard on page 11. (This is a default view.) Properties Open the Properties tab to get the status, version, and other configuration information about the managed system and the operating system that it runs on. The information is in three sections: General shows the IP address, the time since the monitoring agent was started (Up time) such as 15 days 3 hours 47 minutes, and other information. The Status of the highest severity situation event on the managed system is shown with a link to the Situation Events table in the Overview tab, filtered to show only events of the same severity for you to investigate further. Operating System shows the Name of the operating system, the Version installed, and the Manufacturer. For example, Linux el5 from Red Hat. Monitoring Agent shows the availability Status of the monitoring agent, such as ONLINE, what Version is installed, the name of the Tivoli Enterprise Monitoring Server that the agent connects to (Managing system), when the agent received its Last health check, and other information. CPU The CPU tab gives key values related to each processor on the Linux managed system from the CPU and CPU Averages attribute groups. Real time When the CPU tab is set to show real time values only, two of three bar charts and one of two tables are presented. You can cycle through them to display those of most interest. Current Overall CPU Usage (%) plots the overall CPU usage in a stacked bar, based on the sum of User CPU, User Nice CPU, System CPU, and I/O Wait percentages, one stacked bar for each processor and one for the Aggregate. High idle time indicates low utilization, whereas 16 IBM Tivoli Monitoring: Infrastructure Management Dashboards for Servers Reference

27 high utilization of the other metrics might indicate a need to reallocate workloads, increase processor allocation, or upgrade the system. (This is a default view.) System Load Averages plots the amount of CPU allocated 15 Minutes ago, 5 Minutes ago, and 1 Minute ago. By comparing the average over three time periods, you can see how consistent the load average is and identify any unusual load averages. (This is a default view.) CPU Averages (Hourly Updates) plots the CPU percentage current average and moving average for each of these critical CPU metrics: Wait, System, User, User Nice, and Total. CPU Overview table has linear gauges showing the percentage values of pertinent CPU metrics on each CPU and the aggregate: User CPU, User Nice CPU, System CPU, Idle CPU, Busy CPU, I/O Wait, User to System CPU, and Steal CPU. CPU Usage Trends table has linear gauges showing the current average and moving average percentages for Total CPU Used, User Nice CPU, User CPU, System CPU, Idle CPU, and Wait CPU. The table also has an Estimated Days Until CPU Upgrade column. (This is a default view.) Historical After you change the time selection from showing only Real Time to show historical values, the historical line charts are displayed. The charts plot the value for the duration of each time interval in the selected time range. A table that reports real time values for the CPU aggregate is available for additional analysis. Busy CPU (%) - Over Time presents the Busy CPU percentage. Each plotted value is an average of the busy CPU over the monitoring interval. (This is a default view.) User CPU (%) - Over Time presents the percentage of User CPU. User Nice CPU (%) - Over Time presents the percentage of User Nice CPU. System CPU (%) - Over Time presents the percentage of System CPU. CPU I/O Wait (%) - Over Time presents the percentage of I/O Wait. System Load Averages plots the amount of CPU allocated at the sampled intervals. (This is a default view.) Total CPU Used Average (%) - Over Time presents the value of the overall CPU being used at the sampled intervals. The average is based on User CPU, User Nice CPU, System CPU, and I/O Wait percentages. CPU I/O Wait Average (%) - Over Time presents the average of the I/O Wait percentages. User CPU Average (%) - Over Time presents the average of the User CPU percentages. User Nice CPU Average (%) - Over Time presents the average of the User Nice CPU percentages. System CPU Average (%) - Over Time presents the average of the System CPU percentages. Processor Overview - Real Time table presents a linear chart in each cell showing real time percentage values for each CPU and the aggregate. Use the table for comparing with the historical values in the charts and to select one or more CPU instances to be plotted in the charts. By default, the aggregate of all CPUs is plotted. (See also Page layout and controls > Time selector > Managed system dashboard.) Chapter 3. Managed system dashboards 17

28 Memory The Memory tab gives key values related to the Linux managed system. Compare the values in the charts to assess the managed system's memory usage and to detect any bottlenecks that might prompt you to add or redistribute memory. Real time When the Memory tab is set to show real time values only, five bar charts are displayed. You can also view three tables with additional detailed metrics from the VM Stats and Swap Rate attribute groups.

44 Properties Open the Properties tab to get the status, version, and other configuration information about the managed system and the operating system that it runs on. The information is in three sections: General shows the IP address, the time since the monitoring agent was started (Up time) such as 27 days 0 hours 7 minutes, and other information. The Status of the highest severity situation event on the managed system is shown with a link to the Situation Events table in the Overview tab, filtered to show only events of the same severity for you to investigate further. Operating System shows the Name of the operating system, the Version installed, and the Manufacturer. For example, Win2008 Version 6.0-SP2 from Microsoft Corporation. Monitoring Agent shows the availability Status of the monitoring agent, such as ONLINE, what Version is installed, the name of the Tivoli Enterprise Monitoring Server that the agent connects to (Managing system), when the agent received its Last health check, and other information. CPU Different devices compete for processor time by sending a signal to the CPU to interrupt the current process. Use the CPU tab to help detect an excessive number of interrupts on a processor. The CPU tab gives key values related to each processor on the Windows managed system with metrics from the Processor attribute group. Real time When the time selector bar is set to show real time values only, the CPU tab displays bar charts and tables with the following metrics. If there are more processors in the system than will fit in the chart space, the aggregate value is shown along with the individual processors with the highest utilization. CPU Utilization (%) presents the overall CPU usage in a stacked bar, based on the sum of Privileged Time and User Time, one stacked bar for each processor and one for the aggregate. High idle time indicates low utilization, whereas high utilization of the other metrics might indicate a need to reallocate workloads, increase processor allocation, or upgrade the system. (This is a default view.) Interrupt and DPC Acitivty (%) presents metrics for comparing the percentage of DPC Time (interrupt handling), Interrupt Time, and Processor Time, one bar grouping for each processor and one for the aggregate. (This is a default view.) CPU Activity (Interrupts/sec) presents metrics for monitoring the number of interrupts per second, one bar for each processor and for the aggregate. CPU Overview table shows, for every processor and for the aggregate, the same attributes as the bar charts, with linear gauges for the percentage values. (This is a default view.) Historical After you change the time selection to include historical data, line charts are displayed for the selected time period (one plot point for each monitoring interval) along with a related table that reports real time values. 34 IBM Tivoli Monitoring: Infrastructure Management Dashboards for Servers Reference

(See also Page layout and controls > Time selector > Managed system dashboard.) (This is a default view.) Memory The Memory tab gives key values related to the managed system from the VM Stats and Swap Rate attribute groups. Compare the values in the charts to assess the managed system's memory usage and to detect any bottlenecks that might prompt you to add or redistribute memory. Real time When the time selector bar is set to show real time values only, the Memory tab is displayed with five bar charts, which are the default views, and three tables that you can cycle through to see more detailed metrics. Memory Usage (%) plots a bar for each of the major Windows memory resources: physical, virtual, cache and working set. The process-aggregate metrics such as Commit Limit percentage in this chart complement the system-wide metrics such as Commit Limit megabytes in the Total Process Memory (MB) chart. (This is a default view.) Total Process Memory (MB) plots process-aggregate and system-as-a-whole metrics. The system-wide metrics such as Available Physical Memory in megabytes in this chart complement the percentages such as Available Physical Memory percentage in the Memory Usage (%) chart. (This is a default view.) Cache Efficiency (%) plots read hit percentages and data hit percentages. An efficiently executing Windows memory cache has a high cache hit ratio in its various cache access categories, typically 80% or higher, except during system start. (This is a default view.) Paging Activty (per sec) plots the rate of hard page faults (Pages Input and Pages Output), and the combined rate of hard and soft page faults Chapter 3. Managed system dashboards 35

46 (Page Faults). A system can be considered to be a stable state when the rate of hard and soft page faults remains relatively constant. (This is a default view.) System Pool Data plots a bar for number of paged and non-paged processes and the paged and non-paged pool. During Windows operation, space is allocated and deallocated within the pools as requested. When the non-paged part of the System Pool becomes full, the system can hang or fail unless a burst of de-allocations coincidentally occurs. (This is a default view.) Memory Usage, Cache Usage, and Paging tables support the chart views with additional metrics. Percentage values are shown as linear gauges. Historical When the time selector is set to show historical data, the Memory tab shows the first of three panels: Memory Usage. Use the and buttons to cycle through the other panels: Paging File Usage and Paging Activity. Some charts show a single metric. If no data has been gathered for a particular chart metric, no values are plotted. Memory Usage Six of eight historical line charts are displayed from the Memory attribute group to show memory usage by the amount of available physical and virtual memory during the interval in the time range. Real Memory Available (%) - Over Time and Real Memory Available (KB) - Over Time plot the percentage of real memory available and the amount of real memory available in kilobytes, along with the Total Physical Memory (KB). (These are default views.) Committed Memory Usage (%) - Over Time plots the percentage of the committed bytes (virtual memory used) for a selected system during the time period specified. (This is a default view.) Committed Memory Available (KB) - Over Time plots the Committed (KB) (virtual memory usage) and the Commit Limit (KB) size. (This is a default view.)

Paging File Usage Two historical line charts are displayed from the Paging File attribute group to show memory usage by the amount of page file usage during the interval in the time range. A table of real time values is also displayed. Paging Files Usage (%) - Over Time and Paging Files Usage Peak (%) - Over Time present the paging file usage and peak usage as a percentage. 36 IBM Tivoli Monitoring: Infrastructure Management Dashboards for Servers Reference

47 Paging files Usage (%) - Real Time table reports the real time values of the same attributes that are shown in the charts. Use the table for comparing with the historical values in the charts and to select the paging file instances to be plotted in the charts. By default, the aggregate of all paging files is plotted. (See also Page layout and controls > Time selector > Managed system dashboard.) Paging Activity Four historical line charts are displayed from the Memory attribute group showing memory usage by the average amount of paging activity per second during the interval in the time range. Pages/sec - Over Time plots the average number of pages read from the disk or written to the disk per second to resolve memory references to pages that were not in memory at the time of the reference. The value is the sum of the Pages Input/sec and Pages Output/sec attributes. This counter includes paging traffic on behalf of the system cache to access file data for applications. This is the primary counter to observe if you are concerned about excessive memory pressure (thrashing) and the excessive paging that may result. Page Faults/sec - Over Time plots the average number of page faults per second in the processor. Page faults occur when a process refers to a page that is not in its Working Set in main memory. A page fault does not cause the page to be fetched from disk if that page is on the standby list, and hence already in main memory, or if it is in use by another process that the page is shared with. Read and Write Pages/sec - Over Time plots the average Page Reads/sec and Page Writes/sec from the disk or to the disk to resolve pages of virtual memory. Input and Output Pages/sec - Over Time plots the average number of Pages Input and Pages Output per second from the disk or to the disk to resolve memory references. Disk The Disk tab provides key metrics about the disk health on the Windows managed system from the Logical Disk and Physical Disk attribute groups. The tab layout displays two bar charts and a table in the real time display and in the historical display. Real Time When the time selector is set for real time only, the bar charts plot values from the top 5 disks, which includes _Total, with the highest percentages of disk byte traffic, disk usage, and disk time distribution. For a disk with highest values, check to see if the disk appears in another of the top 5 charts. Use the tables to see more metrics from the Logical Disk and Physical Disk attribute groups. Disk Space Utilization (%) - Top 5 plots stacked bars of Used and Free percentages for the five disks with the most space consumed. If disk usage is high, consider reallocating the disk space. (This is a default view.) Chapter 3. Managed system dashboards 37

48 Average Disk Queue Length - Top 5 presents the top five disks with the highest average queue length of requests that were issued to the devices. (This is a default view.) Disk Queue Length (Requests) - Top 5 presents the top five disks with the highest queue length of requests that were issued to the devices. On disks with high queue length, also check if the disk shows in the top 5 for disk usage or average wait time. Disk Transfers/sec - Top 5 plots a stacked bar of Disk Reads and Disk Writes per second for the five disks with the highest transfer rates. Disk Bytes/sec - Top 5 plots a stacked bar of Disk Read Bytes and Disk Write Bytes per second for the five disks with the highest transfer volumes. Logical Disk (This is a default view.), Disk Activity, and Physical Disk tables report metrics from each disk to supplement what is shown in the charts, with linear gauges for the percentage values. Historical When the time selector tab is set to show past data, such as the Real Time - Last 1 Day(s), the following line charts are displayed with historical data samples for the selected time period. The table presents real time metrics. Disk Space Usage (%) - Over Time plots the average percentage of the disk that is used during the historical collection interval. (This is a default view.) Disk Average Queue Length (%) Over Time plots the average number of both read and write requests that were queued for the selected disk during the historical collection interval. (This is a default view.) Disk Free (%) - Over Time plots the average percentage of the volume that is free space during the historical collection interval. Disk Queue Length - Over Time plots the average queue length of requests that were issued to the devices during the historical collection interval. Disk Reads/sec - Over Time and Disk Writes/sec - Over Time plot the Disk Reads and Disk Writes per second to show volume changes. Disk Read (Bytes) - Over Time and Disk Write (Bytes) - Over Time plot the rate at which the system has transferred bytes from a logical disk during read operations and during write operations over the historical collection interval. Disk Usage - Real time table reports current data samples from the Logical Disk attributes. The real time values provide a basis for comparison with the historical values plotted in the line charts. You can select one or more logical disk instances to be plotted in the charts. By default, disk C: is plotted. (See also Page layout and controls > Time selector > Managed system dashboard.) Network Use the Network tab to determine the sources of network activity and identify trends on the Windows managed system. If the managed system shows a high level of network activity overall, you might need to shift some of the load to another system. 38 IBM Tivoli Monitoring: Infrastructure Management Dashboards for Servers Reference

49 Real time When the time selector bar is set to show real time values only, the Network tab presents bar charts and tables with the following metrics: Network Activity (Total/sec) presents the Sent and Received bytes per second as stacked bars. Each bar shows the totals for a network interface object, such as MS TCP Loopback Interface and Broadcom NetXtreme Gigabit Ethernet. (This is a default view.) TCP Segments and ICMP Messages. Bandwidth (%) plots the bandwidth utilization percentage of each network interface object, such as Redirector, Server, and Total CPU. You can compare traffic with bandwidth utilization. (This is a default view.) Failure (%) shows the failure rates of TCP Connections, ICMP Sent Messages, and ICMP Received Messages. (This is a default view.) Network Ports (Count by State) plots a bar for each port state, such as Unavailable and Listening, and the number of ports in that state. If Waiting is high, perhaps a process such as the HTTP server is holding the port open. (This is a default view.) Queue Lengths presents the queue lengths on network interface objects, such as Redirector Current Commands. (This is a default view.) Transmission Rates (Bytes/sec) plots the sent and received packet rate of each network interface object. Connection Counts plots the connection counters for monitoring the success and failure of connections to TCP, which can help you detect bandwidth shortages. DHCP Packet Rates (Packets/sec) shows activity on the managed system if it is a Dynamic Host Configuration Protocol server. If it is not a DHCP server, you get a message says that data is not available; the corresponding DHCP Server table has no data either. DNS Packet Rates (Packets/sec) shows activity on the managed system if it is a Domain Name System server. If it is not a DNS server, you get a message about data not being available. DNS Memory (Bytes) shows the amount of DNS memory on the managed system if it is a Domain Name System server. If it is not a DNS server, you get a message that data is not available. Network Ports, Network Interface, Network Interface IP Addresses, DHCP Server, IP Statistics, TCP Statistics, and UDP Statistics present tables with metrics to supplement what is shown in the charts. You can compare what the NIC devices are doing with what kinds of activities are taking place. Historical When the time selector is set to show historical data, the Network tab shows the first of three panels: Network Interface Activity. You can cycle through the other panels, Network Information and DNS Activity, with the and buttons. Network Interface Activity Two of six historical line charts and a table of current values for each network instance are presented. You can cycle through the charts to see and compare the metrics. Bytes Sent/sec - Over Time and Bytes Received/sec - Over Time plot the rate per second that bytes, including framing Chapter 3. Managed system dashboards 39

50 characters, are sent and received on the interface during the monitoring interval. (These are default views.) Bandwidth (%) - Over Time plots the percentage of physical network adapter bandwidth that was used during the monitoring interval. You can compare traffic with bandwidth utilization. Queue Length (Packets) - Over Time plots the length of the output packet queue (in packets) during the monitoring interval. A long queue length means that delays are being experienced, and the bottleneck should be located and removed if possible. Packets Sent/sec - Over Time and Packets Received/sec - Over Time plot the rate that packets were sent and received on the network interface during the monitoring interval. Activity - Real Time table shows the current values of some of the same attributes from the Network attribute group that you see in the historical charts. The real time values provide a basis for comparison with the historical values. Initially, the most highly utilized network interface device is plotted in the line charts. You can select more instances to plot in the charts. (See also Page layout and controls > Time selector > Managed system dashboard.) (This is a default view.) Network Information The Network Information panel has historical line charts that plot metrics from the Network, DHCP Server, and the TCP Statistics attribute groups for each interval in the selected time range. TCP Connection Failures - Over Time plots the number of times that TCP connections made a direct transition to the CLOSED state from the SYN-SENT state or from the SYN-RCVD state during the monitoring interval. The value also includes the number of times that TCP connections made a direct transition to the LISTEN state from the SYN-RCVC state. (This is a default view.) ICMP Connection Failures - Over Time plots the number of ICMP Messages Received Errors and Messages Sent Errors during the monitoring interval. Some examples of errors are bad ICMP checksums and bad message length. TCP Connection Counts - Over Time plots the total number of the following connection types that were counted over the monitoring interval: Connections Active, Connections Established, Connections Passive, Connections Reset, and Connection Failures.

54 Situation event results dashboard v The situation event results dashboard Details tab has a time selector bar for setting a time range of data samples before or after the event time. Changing the time selection or pressing F5 updates the charts. v The situation event results Details tab shows Last 2 Hour(s) Before Event Occurrence by default, and you can click the button to select a different time range. Managed system dashboard v The managed system dashboard CPU, Memory, Disk, and Network tabs have a time selector bar showing the current time span setting, such as Real Time or Real Time - Last 2 Hour(s). Opening a dashboard page, changing the time selection, or pressing F5 updates the charts and tables with the most recently collected data samples. v The managed system dashboard CPU, Memory, Disk, and Network tabs show Real Time by default. The time zone is based on the settings at the user's computer. For example, if you logged on to the Dashboard Application Services Hub from your browser in the Taipei time zone, the time selector bar shows Asia/Taipei. Charts in real time are formatted as bars and stacked bars. v After you select a historical time range with the time selector bar, the page changes to show past data samples based on the historical collection configuration of the attribute groups on the managed system. For example, if the historical collection definition specifies a collection interval of 15 minutes, the plot points will be at 15-minute intervals starting with the first available interval for the selected time range. v The time range displayed on the charts uses the time zone of the hub monitoring server, which might be different from the user's time zone. For example, if it is 12 noon and you selected Real Time - Last 2 Hour(s) Asia/Jakarta (UTC +07:00), and the hub monitoring server is in Hong Kong (UTC +08:00), the time range shown on the chart is from 11:00 AM to 1:00 PM. v Different charts are displayed from what you get in real time, with one line of data points plotted for each returned row of data. v If a table is displayed, you can filter out instances that clutter the chart display by clearing the check box on a row. If the table has an aggregate row, the other rows are not selected by default. For multiple row tables, the row selection affects the charts that use the same attribute group. For example, of the three check boxes shown here, only the first two rows are plotted: v The color box next to the check box indicates the charted line color for that row. For historical pages with multiples panels, the title bar has and buttons for cycling through the other panels. For example, the Linux Network tab has three historical panels: Network Activity, NFS Activity, and RPC Activity. 44 IBM Tivoli Monitoring: Infrastructure Management Dashboards for Servers Reference

55 v If the historical page layout does not show all the available charts or tables, you have and buttons for cycling through the other charts or tables. v No historical data samples are plotted if historical collection was not configured for the attribute group or if the collection was only recently configured.

Select Time Range After you select Custom from the time selector button in the situation event results Details tab or in the managed system dashboard's CPU, Memory, Disk, or Network tab, the Select Time Range dialog box opens for you to specify a time range of values. Some of the custom time range options for plotting data samples relative to the situation event time are different from the custom time range options for managed system historical charts. Situation event results dashboard Select a situation link from the Situation Events table to see the details about the situation event; in the Details tab, select Custom from the time selector menu to 46 IBM Tivoli Monitoring: Infrastructure Management Dashboards for Servers Reference

57 open the Select Time Range dialog box with the following radio button options for selecting a time range to see before or after (or both) the event occurrence: Last Type or select the number and select the time unit for the time period before the event occurred: Minutes, Hours, Days, orweeks. A default post-event time period of up to two hours is also plotted. Set Time Range Drag the Start and End selectors to change Start Date, End Date, and Time fields. Click or to move another time range into focus. You can also type directly in the fields or click the list to see and select from a calendar and time range. The time range selection must include the date and time of the event. After you click OK, the specified time range is shown in the event results dashboard. The time zone used is based on your computer's time setting. If you close the dashboard and reopen it, the time range returns to the two hours surrounding the event occurrence, which is the default setting. Managed system dashboard After you select a managed system from the managed system group dashboard, information about the managed system is displayed in a tabbed dashboard. Select the CPU, Memory, Disk, or Network tab, and select Custom from the time selector menu to open the Select Time Range dialog box with the following radio button options: Real Time - Last Type or select the number and select the time unit for the time range to display: Minutes, Hours, Days, Weeks, Months, Quarters, oryears. Set Time Range Drag the Start and End selectors to change Start Date, End Date, and Time fields. Click or to move another time range into focus. You can also type directly in the fields or click the list to see and select from a calendar and time range. The Time zone shown is from your computer's time setting. The time range plotted in the chart is from time zone of the hub Tivoli Enterprise Monitoring Server. For example, if you set a time range for the America/New_York time zone (UTC -05:00) and the hub monitoring server is in the America/Arizona time zone (UTC -07:00), the time range plotted begins and ends two hours earlier than your selection. If you do not want that discrepancy, select the Time zone of the hub monitoring server location. For more information, see Time selector in the Page layout and controls topic. After you click OK, the dashboard changes to show historical charts. In some of the tabs, a table of real time data is also shown. The historical time range is also shown in the other managed system tabs (except Overview, Properties, and Process) until you change the time selector option again. Chapter 4. Controls and actions 47

58 Copying the URL After you open another Server Dashboard, the URL in the browser address box does not change for the new location. You can copy the unique URL for the dashboard that you are displaying and use it to open a new browser window with that dashboard or to access later by you or other users that you share the link with. Procedure 1. Open the dashboard from which you want to copy the URL. 2. Click Actions > Copy URL. 3. Right-click the hypertext link (Link to the current page) and select one of the URL options to open the dashboard in a new browser tab or new window, or to copy the URL. Launching to the Tivoli Enterprise Portal You can launch to the Tivoli Enterprise Portal browser client for such tasks as editing situations and acknowledging events. For managed systems that are not supported in the Infrastructure Management Dashboards, you can launch to the browser client to open the default workspace for the managed system or attribute grouping. Before you begin Your portal client user ID must be registered with the Tivoli Enterprise Portal Server. If single sign-on (SSO) has been established, you are not required to authenticate again when you launch to the Tivoli Enterprise Portal. For more information, see Setting up a monitoring dashboard environment with single sign-on and with per user authorization controls in the Preparing your dashboard environment topics of the IBM Tivoli Monitoring Administrator's Guide. Your portal client user ID must be assigned the applications that you can view in the portal client. The list of assigned applications must include the Tivoli Enterprise Monitoring Server if you are not assigned all applications. Otherwise, you receive a KFWITM388E message after performing the launch. For more information, see Administer Users in the Using Tivoli Enterprise Portal user authorization topics of the IBM Tivoli Monitoring Administrator's Guide. About this task Complete these steps to open a new browser window and launch to the Tivoli Enterprise Portal to the default workspace for the current managed system type, individual managed system, or attribute grouping for that managed system. For example, if you launch the portal browser client from the Process tab of the Linux managed system dashboard, the Process workspace for that managed system is displayed. Procedure 1. To supply the information that is needed to construct a URL for the workspace to open, select a managed system type or managed system in one of the Server Dashboards. 2. Click Actions > Launch to TEP. 48 IBM Tivoli Monitoring: Infrastructure Management Dashboards for Servers Reference

59 Results The Tivoli Enterprise Portal is started in your browser. Context information is passed from the dashboard to the Tivoli Enterprise Portal and the associated default workspace is displayed. What to do next If the Tivoli Enterprise Portal does not start, there might be a problem running the browser client for such reasons as the Java plug-in not being installed or configured correctly. You can review the browser client startup information in the IBM Tivoli Monitoring Installation and Setup Guide ( infocenter/tivihelp/v61r1/topic/com.ibm.itm.doc_6.3fp2/install/itm_install.htm) and browser client troubleshooting information in the IBM Tivoli Monitoring Troubleshooting Guide ( com.ibm.itm.doc_6.3fp2/ic/landing_troubleshoot.htm). If you launched to a portal client whose portal server is configured for load balancing, you might receive a message if the portal server goes offline and a secondary portal server takes over and begins servicing requests. The portal client cannot register this switch, and the following message is displayed: KFWITM094W: The Tivoli Enterprise Client has lost contact with the Tivoli Enterprise Portal Server. You must close the browser window and log in again to clear the message. After you are finished with your work session, close the browser tab for the portal client rather than logging out. If you log out, the next time you launch the portal client you are asked to authenticate with the portal server. Setting a trace IBM Infrastructure Management Dashboards for Servers web application has several levels of tracing that you can set while you work with dashboards. You can start a higher level of tracing exactly at the point in the user interface where you are having a problem, then return tracing to a lower level after capturing the necessary log data. Adjust the trace settings to help your administrator or IBM Support to diagnose the cause of problems with the Server Dashboards. For example, if a particular dashboard is behaving unexpectedly, you can raise the trace level before opening the dashboard to log the activity and then return trace logging to the normal level. About this task Take the following steps to set the trace level when you want to increase or reduce the amount of trace logging. Procedure 1. If a Server Dashboard is not already open, select System Status and Health > Server Dashboards and navigate to the dashboard where you want to change the trace level. 2. Click Actions > Trace level and select one of the following levels: Chapter 4. Controls and actions 49

60 v v v v Results Verbose to have all activity logged. Verbose trace level includes Moderate, Light, and Minimal trace logging. Moderate to have variable changes logged, such as what parameters were passed in and what calculations were made. Moderate trace level includes Light and Minimal trace logging. Light to log error and variable activity. You might want to set the trace to this level if you have a problem such as no data being returned but the dashboard continues to function. Light trace level includes Minimal trace logging. Minimal is the default setting and records only unrecoverable errors. You can set the trace level back to minimal after collecting a specific activity sequence. Even if a different trace level was set before logout, the trace is always reset to the lowest level the next time you log in. The trace is adjusted to the level chosen for this and all subsequent dashboards selected. To keep communications traffic to a minimum, the log messages are transferred in batches to the Dashboard Application Services Hub. A final transfer is made after you log out, whether manually or after a timeout period. (If the browser fails, no final logging is sent.) The logs are saved on the server computer and named userid.log.0 where userid is the ID used to log in to the Dashboard Application Services Hub and 0 is the first log. Three log files of 750 KB total are used to record trace data in a cyclical manner: After the userid.log.0 reaches 250 KB, log entries are saved to userid.log.1; after userid.log.1 reaches 250 KB, log entries go to userid.log.2 until it reaches the maximum, at which time userid.log.0 is cleared and new entries are saved there. 50 IBM Tivoli Monitoring: Infrastructure Management Dashboards for Servers Reference
