WMI (PE016) CPU Load and PageFile usage sensors.



Hi This two sensor have error.

The WMI query does not return any results. The reason might be an issue with the host's WMI system. For more information, see https://kb.paessler.com/en/topic/1093. (code: PE016)

When i connect by wbemtest to WMI and run query all is OK

SELECT Name,Timestamp_Sys100NS, PercentProcessorTime
FROM Win32_PerfRawData_PerfOS_Processor
WHERE Name <> '_Total'

cpu pagefile pe016

Hi there,

The WMI query came back empty while PRTG expected a result. This indicates that there is a problem with the host's WMI system. For further suggestions what to do, see I have tried a lot of things to fix my WMI. What else can I try to avoid reinstalling Windows?.
