Server Application Monitor

Cause

The issue is caused when the following Windows Management Instruments (WMI) class is missing:

Win32_PerfRawData_PerfProc_Process

Resolution

Resolution 1:

Restart the WMI service.

Resolution 2:

Reregister PerfMonCounters and WMI classes:

Open an elevated CMD
Reregister the PerfMonCounters and WMI Classes.
1. Open an elevated CMD window on the target system.
2. Go to the following directory:
  cd c:\windows\sysWOW64\
  or
  cd c:\windows\system32
3. Type the following commands (first one for PerfCounters, second cmd for WMI classes):
```
lodctr /R
wmiadap.exe /f
```

If the WMI class is still missing, ensure that the following value is set to zero and not a value of one. Value of one means the performance counter class will be disabled and Orion poller will be unable to poll the server.
```
KEY: “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\PerfProc\Performance”
Field: “Disable Performance Counters”
Value: 0
```

If the entry is found and the value set to 1, set it to 0 and reboot the system.

You may also need to rebuild the performance counters. For information and instructions for rebuilding performance counters, see this Microsoft KB Article for Windows 2008 : (© 2018 Microsoft, available at https://support.microsoft.com, obtained on December 22, 2018).
