PercentIdleTime value is empty in WMI

[guest1]

Am trying to get the processor idle value from windows XP machine(remote) using Win32_PerfRawData_PerfOS_Processor wmi object.

The Idle value is correct for all processors but is not retrieved for "_Total" instance. How can i get the idle time?

Guide me.

Does the data show up in the windows performance counters? If not, then you probably need to rebuild the wmi repository. wmiadap /f

Yes, the data(Idle Time) shows up in windows performance counters. But when i test with wbemtest the value (Idle Time) is shown null.

I got confused because performance counter shows the value but i couldn't get using wmi object.

Guide me.

Thanks.
