Any supported version of the cdm probe installed on a support Windows server.
The cdm probe fetches performance objects for Processor, Memory and System directly on Windows servers (Windows perfmon utility). If the probe is not able to retrieve the values of these counters, QoS metrics cannot be collected.
Reset all the performance counters by executing the following command on your Windows server in a cmd prompt window:
Reboot the Windows Server to take effect
Also via regedit, take note of:
In this key, there could be a Disable Performance Counters value that is set to 1. You may have to reset that value to 0, and then Deactivate and Activate the cdm probe
