Anybody using WMI to read GSX perfmon data?

Google says there's not much activity with the WMI interface but here goes.

I am trying to read root/cimv2:Win32_Perf[*]Data_VMware_VMware over WBEM/WMI and am being told that there are no instances available (sometimes reported as if the class itself does not exist, even while I'm staring at it). Yet the instances show up fine from inside perfmon itself, even when queried from remote systems.

Here is an example, using wbemcli via openpegasus wmi proxy. First query is "get class", second query is "enumerate instances of class":

\[ root# ] wbemcli gc -nl 'http://w2k3ee.labs.ntrg.com:5988/rhino/root/cimv2:Win32_PerfRawData_VMware_VMware'

I'm a real WMI newbie. Other queries to other perf objects (like physical disk and such) work just fine so I'm kind of stumped. Anybody got any ideas here?

PerfRawData and PerfFormattedData have the same behavior

update:[/b] I reset all the relevant permissions, and rebuilt the WMI plugin registry (using wmiadap /c and /f), so all obvious fixes to what might be a security related problem have been tossed.

However, when examining the logs, I see that there are some errors which indicate that the wrong class is being queried so frankly I am starting to wonder if the VMware vmperfmon.dll is broken.

Errors 80041010 and 80041002 seem to be related to misspelled object names. If the DLL is using bad names then that might explain the problem.

Just guessing here. Very odd problem.
