Wmi Service Sensor shows Pagefile usage - even though the pagefile is disabled



Wmi Service Sensor shows Pagefile usage - even though the pagefile is disabled

I do not understand why the service sensor gives these numbers back for running processes. I have confirmed that the pagefile is disabled in windows and the file itself (pagefile.sys) does not exist on the machine.

So what exactly is this number representing?

Hello rsd,

Thank you very much for your contact.

Please allow us to review the WMI results provided by the device that you want to monitor. For this we'll need you to download our latest WMI Tester, run it on the host of the PRTG Probe (Local Probe or the Remote Probe) that has the affected sensor.

Please configure the Domain, Computer name / IP address as well as user and password in the "Basic" tab of the monitored host accordingly. Afterwards, open the "Advanced" tab and select the "Custom" query option. Please use the following WMI query and provide me the result of the tester:
SELECT percentusage FROM Win32_PerfFormattedData_PerfOS_PagingFile WHERE Name='_Total' Thank you very much in advance.
