Performance issue may occur in a large scale environment.

Question

Performance Dashboard graphing may take some time if there is a huge data in SiteScope (SiteScope daily logs)

  • SiteScope server may take a long time to start up in a huge environment
  • Monitor runs are skipped in a large scale SiteScope enviornment
  • Answer

    It is recommended to increase the heap memory assigned to SiteScope.
    On Windows
    Perform the following steps to increase the heap memory assigned to SiteScope :

    1. Traverse to the following location to access registry key:

      HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SiteScope\serviceParam
    2. Double-click on the key, which is present on the right side of the Registry Editor window.
    3. Update the default value:
      Default value: -Xmx512m -Xms512m

      If you have 8GB of RAM on the SiteScope machine, you can assign 50% of the total memory to Xmx and half of its value to Xms. For example, update the value as below:

      -Xmx4096m -Xms2048m
    4. Alternatively, when you run SiteScope as a process, make the above change in the go.bat file available in the following location:
      <SiteScope>\bin\go.bat
    5. Restart SiteScope after making the change.

    On Linux

    1. Traverse to the following location:

      /opt/HP/SiteScope/bin/start-monitor

    2. Update the default value in the file start-monitor
      Default value: -Xmx512m -Xms512m

      If you have 8GB of RAM on the SiteScope machine, you can assign 50% of the total memory to Xmx and half of its value to Xms. For example, update the value as below:

      -Xmx4096m -Xms2048m
    3. Alternatively, when you run SiteScope as a process, make the above change in the go.sh file available in the following location:
      /opt/HP/SiteScope/bin/go.sh
    4. Restart SiteScope after making the change.
