Cause

The issue occurs if the UNIX/Linux monitoring resource pool is deleted

How to solve it!

To resolve the issue, follow these steps:

  1. Create a resource pool for UNIX/Linux monitoring. Give the new pool a different name than the name of the deleted resource pool.
  2. Add the management servers that perform UNIX/Linux monitoring to the new resource pool.
  3. Configure the UNIX/Linux Run As accounts to be distributed by the new resource pool. To do this, follow these steps:
    • In the Operations console, go to Administration Run As Configuration > UNIX/Linux Accounts.
    • For each account, follow these steps:
      – Right-click the account, and then select Properties.
      –  On the Distribution Security page of the UNIX/Linux Run As Accounts Wizard, select More Secure.
      –  In Selected computers and resource pools, select Add.
      –  Select Search by resource pool name, and then select Search.
      –  Select the new resource pool that is created in step 1, select Add, and then select OK.
  4. Run the following PowerShell cmdlet to retrieve the managed UNIX and Linux computers:
    Get-SCXAgent
  5. Verify that the agents that are associated with the deleted resource pool still exist and that the relationship remains.
  6. Run the following command to change the managing resource pool to the one that is created in step 1:

    $SCXPool = Get-SCOMResourcePool -DisplayName "<New Resource Pool Name>"
    Get-SCXAgent | Set-SCXResourcePool -ResourcePool $SCXPool

Resolution

To fix this issue, try the following steps in the given order:

  1. Install the Operations Manager agent by running the following command at an elevated command prompt:

    msiexec.exe /i MOMAgent.msi NOAPM=1

    If the issue persists, go to step 2.

  2. Determine whether the following full registry subkeys exist:HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\HealthService\Performance

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MOMConnector\Performance

    If the issue persists, go to step 3.

  3. Use a tool such as Process Monitor or Process Explorer to determine whether Perfh009.dat is locked by another process. If Perfh009.dat is locked, stop the other process, and then reinstall the operations Manager agent.If Perfh009.dat isn’t locked or if the issue persists, go to step 4.
  4. Rebuild the performance counter library, and then reinstall the Operations Manager agent.
