I have recently enabled dfs replication on a folder from within a mount point and now my sensor will error stating "Query returned "capacity = 0". Can not process data (code: PE088)".

The sensor is monitoring free disk space, via a wmi volume sensor. The folder is on a mount point, not logical disk on a windows 2012 R2 server.

I have other sensors setup exactly the same way and the sensor was working. How can I get this to work again?

Hi,

Thank you very much for your KB-Post. Please use our WMI Tester, run it on the PRTG Host (or host of the Remote Probe) and scan against this particular target, with the following query: Select DeviceID, FreeSpace,Capacity FROM Win32_Volume WHERE DeviceID LIKE '<deviceid>'

Please replace the deviceid-placeholder with the according device ID, copied from the settings of the according sensor in PRTG, and please post the result of the WMI Tester.

best regards.

Below please find the result for the entire volume, as you can see the last one returns with no capacity details. Capacity;DeviceID;FreeSpace 366997504;

If the WMI System already sends no capacity information, you can only try to repair the WMI on the target: The Repair List for WMI problems
