SCOM Rebuilding performance counters

A colleague of mine came across a situation where SCOM performance reports were not working due to corrupt performance counters on a particular server. This situation can be easily resolved by rebuilding the performance counters using the lengthly procedure outlined at http://support.microsoft.com/kb/300956/en-us

Sympton:

Event 10102:

In PerfDataSource, could not resolve counter LogicalDisk, Free Megabytes, C:. Module will be unloaded.

  • One or more workflows were affected by this.     

 

The short version:

On the affected server open an elevated command prompt

Navigate to c:\windows\system32

Type lodctr /R and press enter

 

Shortly you should see the following message:

Info: Successfully rebuilt performance counter setting from system backup store.
