Please provide details
- Windows on target systems? Service Pack? UAC enabled?
- WMI service = WmiApSrv.exe process?
- high CPU = 5%? 20%? 90%?
- what exactly WMI queries you are using?
- how many WMI test items per system? test interval?

its a domain environment using all windows 2k8 R2 std service pack 1.
process name is wmiprvse.exe taking 50% cpu.
process name is wmiprvse.exe*32 taking 50% cpu.

after some investigation we found that TOP process (dominant process) and free physical memory alerts (wmi protocol) are the culprit. when we have disabled this specific alert, cpu gets normal.

High CPU =80 % and 90 %

we are facing issue only on two servers.

2cpu tests and 1 top process cpu and 1 top process memory
Test interval are 1mins and 2mins
