WMI Query works in tester, not in PRTG

Hi -

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.

Thanks, James

Dear James,

technically the Tester and PRTG are the same, therefore it might be worth a try running the PRTG Probe Service under the same account as you ran the Tester under. Does this help?

best regards.

I'm not sure I follow you. The Probe Service runs as Local System. I'm running the WMI Tester on the PRTG server, targeting the problem server, while logged on as a domain admin. The PRTG application uses domain admin credentials to query our Windows servers.

Is there any sort of log I can review on the PRTG installation to see what if any data was received by WMI?

Thanks, James

I am having the same problem. The PRTG server is not part of the domain, but I have domain credentials. From the PRTG server, they WMI Tester works fine, buy I have sensors that occasionally do not respond.

So the sensors work every now and then? Or do they fail all the time?
