Hello,

I have rebooted our PRTG server after our Internet connection was done because of maintenance. Now PRTG shows me an error at one of our Citrix servers. Sensor: CPU Processor Queue Length Message: Class(es) not found: "Win32_PerfRawData_PerfOS_System"

What can I do to resolve this problem?

Hello Joost,

Please use the WMI Testing Tool from your PRTG server to scan against the target device with the Processor query below the advanced tab. Do you get any results?

Best regards
