Monitoring via WMI: Common Problems and Solution Guide
PRTG users often complain about problems and errors when monitoring their systems with PRTG’s Windows Management Instrumentation (WMI) sensors. However, if you encounter issues with WMI sensors, please keep in mind that in most cases WMI errors are the result of a not properly working WMI configuration or WMI installation.
In order to get your WMI monitoring working (again), also in case of single sensor errors, please follow this guide:

2. Check the WMI Connection
If your system meets the requirements as given in the article above and WMI monitoring still does not work, test the connectivity and availability of the corresponding WMI counters. Run our WMI Tester on the same machine that's running the PRTG probe that has the malfunctioning WMI sensors:
