The WMIDIAG tool runs a diagnostic test against a system's WMI configuration and working status, reports any errors, and explains the configuration settings. The WMIDIAG tool is available from the Microsoft website. The download is an exe file that will extract 3 files. Run the wmidiag.vbs script to start the diagnostics scan. If you receive a warning about “Your Default scripting engine is WSCRIPT.EXE”, it may appear that’s not happening, but the scan will still run in the background. After it’s completed scanning it will automatically open a text file with the results.
If you scroll through the file, you’ll see a lot of information about the state of your system, and various performance counters used by WMI. It’s fairly common to see a few ERRORS/WARNINGS in the log, especially for things like “(WBEM_E_NOT_FOUND) Object cannot be found.” At the end of text file you’ll see the overall status for your system. This will either be:
...
- SUCCESS: WMIDiag determined that WMI works CORRECTLY.
- ERROR: WMIDiag detected issues that could prevent WMI to work properly!. Check 'C:\\USERS\\USERNAME\\APPDATA\\LOCAL\\TEMP\\WMIDIAG-V2.1_WIN7_.CLI.SP1.64_CSS-USER_2012.10.16_12.52.59.LOG' for details.
...
If you see the status asking you to check the other log file, check that, as it will contain additional details about your system’s WMI performance.
...
After running the tool, review the configuration for indications of conditions that will prevent up.time from communicating with the WMI system. If errors are reported, as a first troubleshooting step, you should try refreshing the performance counters with the below commands. As they will fix most of the common WMI issues that interfere with up.time’s ability to gather performance metrics.
