I'm trying to get CPU utilization on a Windows Server 2008 system. This should be easy, and I have dozens of other servers on which the WMI CPU sensor works just fine.
I have one particular machine however from which I cannot get any results. I discovered the performance counters were corrupted on the server and rebuilt them. I can now successfully query WMI and get CPU utilization via the WMI Tester and via a third party WMI utility. However, when I use the WMI CPU sensor in PRTG, either with the normal or alternate query, I do not get any results. (Sensor is Up and OK, but no data is received.)
I have also tried a custom WMI query - which likewise works in the WMI Tester - but does not work within the application itself.
Any suggestions would be appreciated.
