wmi 64/32 bits



I have a probe installed on a Windows Server 2008 64-bit. If I run the following commands:

Case 1 - 64 bits C:\windows\system32\wbem\wmic path Win32_PerfRawData_EVAPMEXT_HPEVAPhysicalDiskGroup get Result: Ok, Works well.

Case 2 - 32 bits C:\Windows\SysWOW64\wbem\wmic path Win32_PerfRawData_EVAPMEXT_HPEVAPhysicalDiskGroup get

Result: ERROR, Description = Invalid class

Case 3 - PRTG In PRTG (and wmitester) the error is similar to the second case. 80041010: The specified class is not valid.

This probe was working fine on a Windows Server 2003 32-bit system. How to solve the problem as PRTG?

Please try browsing the WMI available WMI classes using wbemtest to check that the class exists.

You can run do so by executing the command wbemtest.exe which is pre installed on the machine wbemtest.exe | connect | connect | Enum Classes | recursive | OK Is the class available for browsing (the root\cimV2 namespace)?

Are you running the query against the machine the probe is installed on or against a other machine?
