Unstable Results by Using WMI Sensor



I am experiencing the unstable results from WMI sensors especially for Disk Free sensor. The result of Disk Free was up and down from time to time (e.g. 80% -> 0% and 0% -> 80%). I am wondering if the issue is caused by WoW64 bug because the PRTG probe server is Windows 2008 R2 64-bit. Any one could help?

It's very probably NOT the Wow64 bug because this returns incorrect values permanently. We've been reported sporadical 0 values from WMI's disk class but haven't been able to determine the cause and/or a remedy for this behavior.

However, as usual, we're very interested in solutions for such problems - so if anyone knows anything please feel free to contact us at support.paessler.com

Kind regards,
