  8. 8. Using the Performance Management Pack interface This chapter describes the user interface and tools provided with HP ProLiant Essentials Performance Management Pack (PMP). The browser-based user interface facilitates the use of PMP without having a specific management console. PMP data can even be accessed from a remote client if the environment security settings permit. The user interface is standard HTML and JavaScript. For information about modifying the Web environment security settings to enable remote access, refer to HP ProLiant Essentials Performance Management Pack Setup and Installation Guide. HP Systems Insight Manager console integration The performance monitoring service is designed to run on a middle-tier server, which also serves as the HP Systems Insight Manager console server. PMP calculates performance status, updates information available for display on the Systems Insight Manager home page, generates alerts to Systems Insight Manager, supplies information to any online analysis sessions, and logs information to the PMP database. Server status PMP uses the PF column (shown circled in the previous figure) to identify server performance. The status of the monitored servers and their components is depicted using color-coded icons. Each color represents the state of the components and the overall state of the monitored server. • —Unknown. This icon depicts an unknown performance status. • —Normal. Server performance is satisfactory, and there are no pending or existing bottleneck conditions on the server. • —Minor. The server or one of its components might be approaching a bottleneck condition. • —Major. The server or one of its components is currently in a bottleneck condition. • —Critical. The server or one of its components is currently in a critical state. Click any of the system status icons to display the status information for that server. A Normal, Minor, or Major icon in the PF column of the Systems Insight Manager console indicates the specified server is being monitored and summarizes the server status. Using the Performance Management Pack interface 8
  9. 9. Server status applies only to servers currently being monitored. An Unknown icon for a specific server in the PF column of the Systems Insight Manager console indicates that performance information is not available for that server. Clicking the Unknown icon for a server displays detailed reasons why the information is not available. An Unknown icon might appear for any of the following reasons: • A server is not licensed. • A server is licensed but not marked for monitoring. • A server is marked for monitoring, and PMP is in the process of judging the status of the server while gathering the requisite number of samples. • PMP finds that a server has changed configuration and has not yet taken a fresh snapshot of the configuration or is in the process of judging the status of the server while gathering the requisite number of samples. A critical status (a red icon with an “X”) indicates a critical problem with communication between the performance monitoring service and the monitored server. When PMP finds that the server is not reachable at a first attempt, it sets the status to critical. If PMP monitors a server without problems, and then unsuccessfully attempts to reach the server twice, the Critical icon appears. Click this icon to display the reason for the problem. The server might be unreachable for the following reasons: • The server is powered off. • The network connection between the monitored server and the middle tier (analysis server) might not be open in both directions. • The monitored server might not meet the minimum requirements. For a complete list of supported monitored servers, refer to HP ProLiant Essentials Performance Management Pack Support Matrix. • One or more HP Management Server agents are not running on the server, and PMP cannot collect the information required. • HP Management agents have been downgraded. Server licensing and administration information can be accessed from the HP Systems Insight Manager console toolbar by clicking Options>Performance Management Pack Options. For more information about administration and licensing, refer to HP ProLiant Essentials Performance Management Pack Setup and Installation Guide. Online and Offline Analysis The PMP Online and Offline Analysis tools provide an intuitive interface to detail the performance status and inventory of monitored servers and the processors, memory, local and external storage, network storage, network connections, host bus and virtual machine host components for each server. The tools provided for Online and Offline Analysis are similar in overall functionality. The major difference in performing Offline Analysis is that the data comes from a database rather than a real-time data stream. Additionally, if you want to obtain performance analysis in a static setting, PMP provides many tools to assist in monitoring server performance. For additional information about Offline Analysis, refer to Chapter 2 of this guide. When a monitored server icon is selected from the PF column of the Systems Insight Manager console, or when you select Diagnoze>Performance Management Pack>Online Analysis from the console toolbar, the PMP Online Analysis screen appears in a new browser window, as illustrated in the following figure. The analysis starts in the performance status view for the server. Using the Performance Management Pack interface 9
  10. 10. The interface is divided into three frames. Systems detail frame The Systems detail frame appears at the top left side of the browser window below the banner and provides the following information: • Server name—Displays the name of the server currently being monitored • Server OS—Displays the operating system version of the server currently being monitored • Server IP—Displays the IP address assigned to the server currently being monitored • Sample Rate—Displays the frequency with which the agents are collecting performance data on the monitored server • Samples for Status—Displays the number of samples averaged to determine system performance status • Alert—Indicates if alerts are to be sent when certain server performance status conditions occur • Log—Indicates if the performance data is currently being logged for the selected server • Set Threshold—Provides a link for modifying the performance threshold values for the selected server Server Tree frame The Server Tree frame appears on the left side of the browser window. This frame is used to navigate between system components. Component performance and status information appear in a hierarchical tree, with nodes for each level of the component. This frame provides a view of the server, processors, memory, network connections, storage, host bus components and virtual machine host components. Results frame The Results frame displays the status, inventory, and graphical representation for the selected server and its components. Use the tabs in the Results frame to switch between these views. A list of the values corresponding to each server and its components is provided in Appendix A of this guide. The Results frame includes tabs to access the different representations of the information available for the server and its components. The tabs are labeled Status, Graph, and Inventory. The tabs provide the following general information: • Status—Lists the performance counters (metrics) associated with the selected component. The table provides the average, maximum, minimum, and last (current) values for all the counters. A status icon indicates the performance of the component. An increasing level of severity is indicated as the status changes from normal to major. The Status tab includes the “Analysis Explanation,” explaining why a bottleneck exists, the Using the Performance Management Pack interface 10
  11. 11. “Recommendation,” providing possible actions to relieve the bottleneck, and the “Configuration Issues,” providing details about any issues detected for the components. The server metrics and their definitions for data analyzed by PMP to determine the status of a particular component are provided in Appendix A of this guide. • Graph—Displays a graphical representation of the performance metrics associated with the selected component. The graph is dynamic, changing as the values change, and contains the last 25 measurements taken. • Inventory—Displays information about the selected component configuration, such as the processor or NIC configuration. Information provided in the Inventory view is detailed in Appendix A of this guide. The Results frame provides a Help icon in the top right corner, which displays a context-sensitive help page. Network Storage Analysis Network storage is licensed separately. Network storage Online Analysis appears in a new window separate from server analysis. Using the Performance Management Pack interface 11
  12. 12. Reports PMP can generate reports illustrating the percentage of time a system was in a bottleneck state and the overall performance utilization for a system categorized by its components. A System Summary Report can be generated from data in the performance database in HTML format. CSV File Generator can generate comma-separated value (CSV) files for import into desktop analysis or reporting tools. A Static Analysis Report is an analysis of the hardware configuration for the server as a whole, identifying potential problem areas. The Server availability report in the HTML format consolidates information on availability of servers at any point in time. The CSV file documents each individual sample for every component analyzed, collecting different measurements for each. All report formats can generate reports for either one designated system, or a group of systems as a whole. For information about generating reports, refer to Chapter 2 of this guide. A sample CSV file and a list of associated values measured for each server and its components are provided in Appendix A of this guide. A sample System Summary report and Static Analysis report are provided in Appendices B and C of this guide. The reports that are generated through PMP are stored in the following location: C:Program FilesHPPerformance Management Pack 4PMPToolshtmReports This is the default location for the generated reports. Using the Performance Management Pack interface 12
  13. 13. Offline Analysis Offline Analysis is used to view recorded data sessions from the database, enabling review of specific logged information sampled from the database. For information about using Offline Analysis to view recorded data sessions, refer to Chapter 2 of this guide. During the session, data is shown in two refresh modes. • Auto mode—Plays the data back at the selected playback rate. Select the Auto Refresh checkbox to enable auto mode. • Manual mode—Enables you to advance the samples manually. Click any navigation button to enable manual mode. Manual mode navigation buttons consist of: • : To the first sample • : To the previous bottleneck • : To the previous sample • : To the next sample • : Forward to the next bottleneck • : To the latest sample Using the Performance Management Pack interface 13
  14. 14. Manual Log Purge Manual Log Purge is used to delete logged files from the PMP database that are no longer needed. For information about using this tool to delete logged files, refer to Chapter 2 in this guide. Using the Performance Management Pack interface 14
  15. 15. Using PMP This chapter provides an overview of PMP functionality. A usage scenario demonstrates setup, administration, and monitoring of servers. The usage scenario provides examples of bottleneck conditions with and without a recommended hardware upgrade, as well as examples of static and offline analysis. Opening the Systems Insight Manager console The Systems Insight Manager console, displayed in an Internet Explorer browser window, shows performance status in the PF column. Icons in this column indicate the current performance state of a server. For additional information about performance states, refer to Chapter 1 of this guide. In the following figure, an amber (major) icon indicates a bottleneck condition exists on the server named “pmpserver.” This server is referenced in the following sections. Using PMP 15
  16. 16. Debugging a server bottleneck condition The following sections detail the appropriate actions to take when a bottleneck condition exists on a server. In this scenario, the server name is “pmpserver.” Select the server Click the major icon to display the PMP Online Analysis window for “pmpserver.” The screen displays the server node tree in the left configuration navigation pane and the Status tab in the right pane. The counters displayed in the following figure are selected items from the various components. The Analysis Explanation indicates that at least one node has a problem. The problem or problems with a server can also be seen within the configuration navigation pane. The tree structure in the configuration navigation displays the configuration of each node, down to the individual components monitored by PMP. The icons used in the tree next to a node or component indicate the performance status for that item or the item under the node. The performance status icon for the selected node is also displayed in the Results frame. PMP indicates many problems for the server in this example. Generally, only one node has a problem because bottlenecks tend to mask one another. Using PMP 16
  17. 17. Display the memory status Click Memory in the navigation tree to access the memory information and display the status page for memory in the right pane. Related and important counters for memory appear in the Analysis Data table. The explanation details a high average page read rate (reading from disk), and the available physical memory is less than 20 MB. This condition indicates that the system needs more physical memory to handle the load, and this recommendation is made. Many, but not all, recommendations suggest adding hardware. In this example, the situation could have occurred because a new batch job was assigned to run on the server at night. The remainder of this scenario examines other performance information available to assist in making a judgment regarding the problem and determine if immediate action is required to resolve the performance bottleneck. Display the memory graph Select the Graph tab to change the right pane to a graphical display of memory counters. Using PMP 17
  18. 18. This graph displays the last 25 samples taken for the server. The duration of the graph is 25 times the sampling rate of 10 seconds, or 4.16 minutes, as shown near the upper-right corner of the screen. The graph displays what occurred on the server from 1:13 to 1:17 P.M. The pattern of the curves is rising, peaking, and declining, which might be caused by the completion of the new batch job. In this case, the problem is over and the performance information is logged to the database for later review using the Offline Analysis tool. Contrasting the graphical display The following sections provide details to further illustrate the power of the graphical display and demonstrate the full depth of analysis. Expand the local storage Click the + icon next to Storage in the configuration tree to expand the tree structure and select the storage node for display. Using PMP 18

Display the VM guest processor status Click Processor in the navigation tree to access the VM Guest processor information and display the status page for the VM Guest processor in the right pane. Related and important counters for VM Guest Processor appear in the Analysis Data table. The Analysis Explanation indicates that “Processor utilization is extremely high (over 90%) and probably causing performance degradation.” Using PMP 31
  32. 32. Performance Issues with no hardware upgrade recommendation The following scenario provides an example of a recommendation that does not suggest additional hardware. In the following figure, a major status icon is displayed for the processors. The recommendation suggests determining if the processing load can be distributed more evenly across the available processors. This recommendation indicates that more than one logical processor exists in the system and at least one processor is not fully utilized. The recommendation demonstrates not only a non hardware related solution, but also the specificity of PMP. Had this been a different component or subcomponent, the recommendation would have been specific to that component. Using PMP 32
  33. 33. Performing a static analysis The following sections provide examples of using static analysis. General Usage Performance issues are often introduced during system configuration. This might be caused by a planning error, an error in following the prescribed configuration path, or a result of many updates to a system over time. Regardless of the cause, PMP can analyze static configurations and make suggestions to areas of concern before a change occurs. From the Systems Insight Manager console toolbar, click Reports>Performance Management Pack Reports>Static Analysis Report, select the “pmpserver” checkbox, and click Generate Report to display the Static Analysis Report for “pmpserver.” These results can be printed from the browser. Using PMP 33
  34. 34. Half duplex port Scan through the report shown in the following figure. The first potential issue is indicated by the message “At least one port is running in Half Duplex mode.” PMP indicates that a network port is running half duplex, which can cause a bottleneck. In this case, half duplex was set in error, and it is causing an artificial bottleneck for network traffic over that port. Using PMP 34
  35. 35. Unassigned disks The next message that might indicate a problem in the report is “One or more physical disks are not assigned to an array.” In many cases, this condition might be expected, particularly if online spare drives are configured because they are not part of an array set. However, this condition might be unexpected because of an interrupted array configuration attempt. Using PMP 35
  36. 36. Reduced SCSI speed The message “At least one drive is running at a reduced SCSI speed on SCSI Port 1” appears in the report. In this example, the HP ProLiant DL380 server was configured correctly with a new Smart Array controller and Ultra-320 drives, but the drives are not running at Ultra-320 speed. Further examination of the hardware reveals an older SCSI cable as a potential problem. Testing reveals that the differential pin on the SCSI cable is bad, causing the drive and controller to revert to SCSI-2 speed for transmission. PMP detected the potential performance problem and helped narrow the cause before any product work on the server. Host bus balancing Although there are no error messages displayed in this static analysis, it is important to note that PMP can help determine how the devices in a system are laid out across the host buses and what issues might arise from bus overloading. Performing Online and Offline Analysis The following sections provide instructions to use PMP Online and Offline Analysis. Online Analysis The PMP Online Analysis tool enables performance data to be viewed from a real-time data stream and provides an intuitive interface to detail the performance status and inventory of monitored servers and their components. In the previous example, Online Analysis is used to determine that the system required more physical memory to handle the assigned load balance. To use Online Analysis, either click the monitored server icon from the Systems Insight Manager PF column, or: 1. From the Systems Insight Manager console toolbar, click Diagnose>Performance Management Pack>Online Analysis. 2. Select the checkbox next to the server or servers for which to view performance data. The checkbox at the top of the column can be used to select all of the servers listed on the page. 3. Click Apply Selections>Run Now. Online Analysis appears in a new window. Using PMP 36
  37. 37. IMPORTANT: When Online Analysis is started for a server, an Online Analysis session is started automatically for any licensed network storage enclosure connected to that server. IMPORTANT: As PMP supports VMware ESX 2.5.2, 2.5.3, 2.5.4, 3.0, and 3.0.1, there are differences in the way PMP analyzes servers running with VMware ESX operating systems. If you have VMware ESX operating system installed and you have not configured Virtual Machines, PMP treats this ESX operating system as a server similar to a Linux operating system. However, there is no difference in the data analysis. TIP: If you have VMware ESX operating system installed, and you have configured Virtual Machines, PMP treats this server as a VM host. When PMP identifies the server as a VM host, it is mandatory that it is licensed through VMM. When the VM host is licensed through VMM, PMP collects performance data of the host. However, PMP displays only limited performance data. PMP analyzes performance of the processor subsystem and is presented to the server. In addition, in the Online and Offline Analysis pages, only the Inventory Tab is present for the child nodes of 'Storage', 'NIC' and 'Host Bus' subsystems TIP: Redirect icon for the VM Host will appear only when the associated VM Guests are being monitored. Offline Analysis The Offline Analysis tool enables performance data to be viewed from a database that has been captured and logged over a specified time. This tool enables manipulation of the rate at which data is played back for analysis by speeding or slowing the refresh rate or selecting specific points in the presentation of previously captured events without regard to chronology. In the previous example, it was determined that the system required more physical memory to handle the assigned load balance. Offline Analysis enables examination and analysis of precisely what occurred on “pmpserver” between 3.01 to 3.37 P.M. when a problem occurred. The Offline Analysis tool is used to view recorded data sessions from the PMP database. To use Offline Analysis: 1. From the Systems Insight Manager console toolbar, click Diagnose>Performance Management Pack>Offline Analysis. 2. Select the checkbox next to the server or servers for which to view performance data. The checkbox at the top of the column can be used to select all of the servers listed on the page. 3. Click Apply Selections>Run Now. 4. Select the start date and refresh rate for which to display performance data. The refresh rate determines the rate at which the logged data is played back. 5. Click Start Offline Analysis. After selecting offline analysis parameters, the session appears as illustrated in the following figure. For information about navigation tools and the tabs provided with this interface, refer to Chapter 1 of this guide. Using PMP 37
  38. 38. The following icons are provided for bottleneck navigation: • — Go back to the previous bottleneck • — Go forward to the next bottleneck For example, if a status change happens at 6:00 A.M. from green to amber, yellow to amber, or green to yellow, click the next or previous bottleneck navigation button and the Offline Analysis page for 6:00 A.M. appears. However if status changes at 6:00 A.M. from amber to yellow, amber to green, or yellow to green, the next bottleneck button will not navigate to that time. PMP Offline Analysis can detect hardware configuration changes. A message appears when a configuration change is identified, as shown in the following figure. Data reporting Because PMP can be configured to store all performance data measurements analyzed, stored data can be converted to reports. Reports are generated from Systems Insight Manager. The report, when generated for a specific server, provides a summary of the performance statistics for the time range selected. Using PMP 38

  45. 45. Licensing Servers To license servers for PMP, use one of the following pages: • Configuration page • Online Analysis page Licensing Servers using the Configuration page To license servers using the Configuration page: 1. From the HP SIM console toolbar, select Options>Performance Management Pack>Configuration. The Verify Target Systems page appears. 2. Select the servers you need to license and click Next. NOTE: If you need to remove a server from the list, select the server name and select Remove Target. The Licensing Setup page appears. The information in this page is categorized in the following sections: • All Licensed Devices This section lists all the devices that have already been licensed. • All Devices not available for Licensing This section lists all the devices that cannot be licensed. It also lists the reason why this server cannot be licensed. For example, the device may not be a supported server, or it does not have a serial number or it is part of a configuration that is not supported. Even if the management agents running on the managed node are not supported, the device is not available for licensing. When the device is of an unsupported configuration, run Software Status Polling for the server. In the HP SIM console, select Status Polling>Software Status Polling. In the Verify Target Systems page, select the server and click Run Now. • All Devices available for Licensing This section lists all the devices that are available to licensing. PMP maintenance 45
  46. 46. 3. Click Next. The License unlicensed systems page appears. This page displays the number of available licenses and the number of servers that need to be licensed. If the number of servers to be licensed is more than the number of available licenses, you need to add a key using Add Key. For more information on adding a key, see Adding Licenses section later in this chapter. NOTE: When there are no servers available for licensing, the page displays the Previous and Run Now buttons. Selecting Run Now displays the monitoring page. 4. Select the server that you need to license and click Apply License. The servers are now licensed and can be monitored. NOTE: The servers are licensed if there are sufficient licenses. 5. To monitor the servers, click Run Now. The PMP Monitoring page appears. PMP maintenance 46
  47. 47. Adding Licenses While licensing a server, it is possible that the number of servers that need to be licensed exceed the number of licenses that are available. In such cases, a license or a key must be added to license the additional servers. To add a license: 1. In the HP SIM console toolbar, select Deploy>License Manager. The Product License Information pane appears. 2. Select Performance Management Pack and click Manage Licenses. The Manage Licenses pane appears. 3. Click Add Licenses. The Add Licenses pane appears. 4. Enter an available license key. License keys are located on the sticker included with the PMP license kit. 5. Click OK. The added license is displayed in the Manage Licenses page. IMPORTANT: The license key field is case-sensitive. Only numerals and uppercase letters are acceptable entries. 6. Select the servers you need to license and click Apply License. 7. Click Run Now to license the server and to make it available for monitoring. Besides adding a license when attempting to license a server, you can add licenses to the databases independently as well. There are two ways you can add a license to the database: • Add a license individually • Add a license from a file Adding a License Individually To add a license individually: 1. In the HP SIM console toolbar, select Deploy>License Manager. The Product License Information pane appears. 2. Select Performance Management Pack and click Manage Licenses. The Manage Licenses pane appears. 3. Click Add Licenses. The Add Licenses pane appears. 4. Enter the key in the five text boxes. Be sure to enter five characters in each field. The cursor automatically advances to the next field when the current field is full as you enter the key. Optionally, you can copy and paste a key. NOTE: When you paste the complete key, it can be in the groups of five characters, each group separated by a hyphen. For example, #####-#####-#####-#####-#####. Be sure not to include space between the characters and the hyphens. 5. Click Open to view the details of the key. 6. Click Add License to add the new license to the database. If no error message is displayed, then the license key is valid and will be added to the database. If the license key is invalid, an error message is displayed and the license key is not added to the database. PMP maintenance 47
  48. 48. Adding a License from a file Through HP SIM, you can add one or more keys to the database by saving it in a file, and then uploading it into the database. The file must be in the XML format and must be saved with a key extension. The file can contain any number of keys in it. Once the file is uploaded, all the keys saved in it are automatically added to the database. You can create a file and add the keys to it. However, be sure to follow the following format: <?xml version="1.0" encoding="UTF-8"?> <KEYLIST> <KEY> <KEYSTRING>A2345-1B345-12C45-123D5-123E5</KEYSTRING> <KEYSTRING>A2345-2B345-32C45-123D5-423E5</KEYSTRING> </KEY> </KEYLIST> To add licenses to the database from a file: 1. In the HP SIM console toolbar, select Deploy>License Manager. The Product License Information pane appears. 2. Select Performance Management Pack and click Manage Licenses. The Manage Licenses pane appears. 3. Click Add Licenses from File. The Add Licenses from File pane appears. 4. Enter the complete path and file name in the Specify a file name and path field. Alternatively, you can click Browse to locate the file. 5. Click Open. 6. Click Add Licenses to add all the keys into the database. Licensing Servers using Online Analysis page In addition to licensing servers from the Configuration page, servers can also be licensed from the Online Analysis page. To license servers using the Online Analysis page: 1. From the HP SIM console toolbar, select Diagnose>Performance Management Pack>Online Analysis. The Online Analysis page appears. The subsequent steps in licensing servers using the Online Analysis page are the same as the steps to license servers using the Configuration page. For information about purchasing PMP licenses, refer to http://www.hp.com/products/pmp. PMP maintenance 48
  49. 49. Network storage licensing Network storage enclosures must be individually licensed before performance data can be viewed using PMP. In addition, each server attached to the network storage enclosure must also be individually licensed before performance data can be viewed for that server or the server component, including the network storage component. The network storage Licensing Administration page is accessed from the Online Analysis page of the server to which the storage is connected by clicking the “redirect” icon next to the network storage enclosure. The network Storage Enclosure License Administration page appears, displaying the network storage enclosure name, model, and available number of licenses. Clicking Apply License licenses the network storage, if there are licenses available. An Online Analysis session for the network storage enclosure starts automatically when Online Analysis is started for the server to which the enclosure is attached. For additional information about applying network storage licenses and adding licenses to PMP, refer to Chapter 5 of the HP ProLiant Essentials Performance Management Pack Setup and Installation Guide. Free licenses and demo license For information about free licenses and demo licenses, refer to Chapter 5 of the HP ProLiant Essentials Performance Management Pack Setup and Installation Guide. PMP maintenance 49
  50. 50. Licensing cellular Integrity systems The procedure to license cellular Integrity systems varies from the procedure to license other servers. To license the cellular Integrity systems 1. Log into HP SIM. The All Systems page appears. 2. Select the server you need to license and click Option > PMP > Monitoring Administration. The Verify Target System page appears. 3. In the Verify Target Systems page, if you select Next, the Integrity system is automatically licensed. The system is listed in the licensed system table in the Licensing Setup page. If there are not enough licenses, the Integrity system will be listed under Server Available for Licensing. In the License Status column, the following message is displayed: "No available licenses." In this case, you need to add a license. For more information on adding licenses, see Adding Licenses. Licensing VM Hosts and VM Guests The procedure to license VM Hosts does not vary from the procedure to license other servers. However, as a prerequisite, the VM Host must be licensed in VMM. The VM Host cannot be licensed for PMP if it is not licensed in VMM. The VM Guests do not need any license for PMP and all VM Guests will be displayed in the Licensing Administration page -> All Devices Not Available for licensing list with the license status as “VM Guest”. TIP: If a server is licensed for PMP and then converted to a VM Host, it is not required to license the VM Host again for PMP, but PMP will expect that the same VM Host be licensed for VMM. The VM Host can be monitored only when licensed by VMM. Similarly, if a VM Host is converted to a physical server, it is not expected to be licensed again for PMP. NOTE: To license a server for VMM, refer to the VMM documentation. Monitoring administration Servers are monitored based on monitoring parameters. The monitoring status, log days and the number of samples are set in PMP for servers and storage enclosures you want to monitor. PMP maintenance 50
  51. 51. Changing server monitoring status Servers that are licensed for monitoring are displayed on the Monitoring Administration page with a checkbox next to them. Servers that are currently being monitored by PMP appear with “Started” as the value in the Monitor Status column. Servers that are not currently being monitored have no value in the Monitor Status column. Note the default values for monitoring status and number of samples listed beside each server. The server list displayed on the Monitoring Administration page can be filtered to display all devices, all monitoring devices, all devices available for monitoring, all alerting devices, all devices available for alerting, all logging devices, or all devices available for logging. Select the appropriate filter from the dropdown box next to View. Use the page links which appear when there are multiple pages for navigating between pages. NOTE: The view filter is not applicable for the VM Guests. The VM Guest will not appear for the filter “All devices available for monitoring” even though it is not marked for monitoring when the host is being monitored. This will only appear in the list depending on the VM Host status, that is, if the VM Host is not marked for monitoring, then all the associated VM Guests will appear in this list. Similar conditions apply for Alert and log. NOTE: The monitoring of VM Guests will automatically be stopped if the associated VM Host is stopped for monitoring. To change the monitoring status for a particular server: 1. From the Systems Insight Manager console toolbar, select Options>Performance Management Pack Options>Configuration. 2. Select the Server tab. Servers or network storage enclosures available for monitoring appear in the list. 3. Identify the server for which to change monitoring parameters from the server list, and select or deselect the box next to the server. The checkbox at the top of the column can be used to select or deselect all of the servers listed on the page. 4. Select or deselect the monitoring parameters (Monitor/Alert/Log) for the server, and select log days and the number of samples to use to determine status from the dropdown list. 5. Click Apply. The changes made to the monitoring status of the server are updated. Selected servers begin a new monitoring session with the updated parameters, terminating any current monitoring session. Enabling network storage logging Network storage enclosures that are licensed and connected to servers currently being monitored are automatically monitored. These enclosures appear on the Monitoring Administration page with a checkbox next to them. PMP maintenance 51
  52. 52. To enable logging for a network storage enclosure: 1. From the Systems Insight Manager console toolbar, select Options>Performance Management Pack Options>Configuration. The Monitoring Administration page appears in a new window. 2. Select the Network Storage tab. Network storage enclosures licensed and currently being monitored appear in the list. 3. Select the checkbox next to the storage enclosures for which to enable logging, or use the checkbox at the top of the column to select or deselect all of the items listed on the page. 4. Select the Log checkbox, and select the log days, the number of samples to use to determine status from the dropdown menu. 5. Click Apply to begin logging. 6. To disable logging, repeat steps 1 through 5, deselecting the Log checkbox. Data is only logged to the PMP database for storage enclosures after logging is selected and parameters are applied. Network storage logging is independent of the connected servers. For example, data can be logged for a storage enclosure while not being logged for the connected servers. Enabling VM Host and VM Guest logging VM Guests that are configured on the VM Host that is currently being monitored are not automatically monitored. These VM Guests appear on the Monitoring Administration page with a checkbox next to them. These VM Guests can either be selected individually or collectively using the “Virtual Machine Guests” group check box. PMP maintenance 52
  53. 53. To enable logging for VM Guests: 1. From the Systems Insight Manager console toolbar, select Options>Performance Management Pack Options>Configuration. The Monitoring Administration page appears in a new window. 2. Select the Server tab. Servers or VM Hosts and VM Guests available for monitoring appear in the list. 3. Identify the VM Guest for which to change monitoring parameters from the list, and select or deselect the box next to the VM Guest. The checkbox at the top of the column can be used to select or deselect all of the items listed on the page. 4. Select or clear the monitoring parameters (Monitor/Alert/Log) for the VM Guest. 5. Click Apply. The changes made to the monitoring status of the server are updated. The selected VM Guests begin a new monitoring session with the updated parameters, terminating any current monitoring session. Data is only logged to the PMP database for VM Hosts and VM Guests after logging is selected and parameters are applied. VM Guest logging is NOT independent of the connected VM Hosts. For example, data cannot be logged for a VM Guest while not being logged for the connected VM Host. IMPORTANT: To monitor, alert and log the VM Guests you must enable monitoring, alert and log for the associated VM Host. NOTE: The sample rate, log days and the number of samples cannot be set for the VM Guests but will use the same values that are set for the VM Hosts. Monitoring parameters PMP monitoring can operate in four modes: • Monitor—Enables monitoring of the status of servers, updating information displayed by Systems Insight Manager and Performance Management Pack. Analysis information and debug performance issues can be viewed using the Online Analysis tool. • Monitor & Alert—In addition to the capabilities enabled with “Monitor,” this mode sends alerts to Systems Insight Manager whenever the status of a server changes. • Monitor, Log, & Alert—In addition to the capabilities enabled with “Monitor & Alert,” this mode stores detailed performance information in the PMP database for later reporting or playback, using the Offline Analysis tool. PMP maintenance 53
  54. 54. • Monitor & Log—Enables monitoring of servers and stores the performance in the PMP database for playback later. When monitoring is started for a server, the alert and log status in the table will reflect that the Alert and Log options are chosen. When the monitoring is stopped, the table will always show the previous state of Alert and Log status. The following scenario explains the details. Sl # Check box options Results in the table Monitor Alert Log Monitoring Alert Log 1 2 3 4 5 6 7 1. Row number 1: Monitoring is started, Alert and Log enabled. The results will be Started, Tick and Tick in the table. 2. Row number 2: Monitoring, Alert and Log disabled. The results will be Blank, Tick and Tick in the table reflecting the previous state of Alert and Log when the monitoring is stopped. 3. Row number 6: Monitoring is started, Alert enabled and Log disabled. The results will be Started, Tick and Blank reflecting the current status whenever the monitoring is started. 4. Row number 7: Monitoring, Alert and Log disabled. The results will be Blank, Tick and Blank reflecting the previous state of the Alert and Log when the monitoring is stopped. Number of samples The Number of Samples setting allows adjustment of the analysis of PMP to account for highly variable or stable system performance. A higher number of samples used results in smaller average changes in performance and, therefore, generates fewer performance bottleneck indications for a server whose performance changes wildly. A smaller number of samples can be used for servers with more stable performance or when the sampling rate is higher. Performance threshold setting The hyperlink To Set Performance Threshold values click here allows setting the performance threshold values for the selected server in a separate page. For more information, see section “Set Performance Threshold”. Modifying the sample rate PMP does not control the amount of time between samples. Instead, the sample rate (data collection interval) is set from within the HP Management Agents. The Management Agents can be modified from the Control Panel or Internet Explorer. The sample rate for a network storage enclosure is determined by the servers to which the enclosure is connected. The sample rate for the storage enclosure is the highest sample rate of the connected servers. Modifying Log Days The Log Days option allows you to choose the number of days that you need data logged for. You can select a value for this option using the two drop down lists. The first drop down list contains values starting from 1 to 20. The other drop down list contains options such as Day(s), Month(s) and Year(s). For example, if you select 2 in the first drop down list, and select Year(s) in the second drop down list, data is logged for 760 days. The data that was logged first is cyclically replaced as data is logged. Modifying Management Agents from the Control Panel 1. Open HP Management Agents from within the Control Panel. 2. Select the SNMP Settings tab. 3. Modify the Data Collection Interval (sample rate) as necessary. PMP maintenance 54

The threshold values are set only for the server being analyzed. 2. Click Apply to set the threshold values. 3. Click Cancel to go back to the online Analysis. PMP maintenance 58
  59. 59. Threshold values The threshold setting for the various subsystems allows adjustment of the analysis of PMP to account for highly variable or stable system performance. A higher value used results in smaller average changes in performance and therefore, generates fewer performance bottleneck indications for a server whose performance changes wildly. A smaller value can be used for servers with more stable performance or when the sampling rate is higher. Manual Log Purge Manual Log Purge enables the recorded sessions for a logged server or network storage enclosure, logged in the PMP performance database and occupying hard disk storage space, to be deleted. Use this tool regularly to remove unwanted recorded sessions and reduce database size. To delete records in the performance database: 1. From the Systems Insight Manager console toolbar, select Options>Performance Management Pack Options>Manual Log Purge. 2. Select the checkbox next to the server or network storage enclosure for which to delete logged data. 3. Select to delete data older than a specified number of days or a specified date. NOTE: Data acquired for the current date of the analysis server cannot be deleted. 4. Click Delete Selected Data to remove the data from the performance database. PMP maintenance 59
  60. 60. Appendix A Sample CSV file PMP enables you to generate many reports, and each user can have a different set of requirements. Therefore, PMP supplies all of the performance information gathered in a file that can be read by many desktop-reporting tools, including Microsoft Excel. The following figure depicts a summary report generated in CSV file format and displayed in Microsoft Excel.
