WMI Class Reference for Dynamics CRM Performance Counters

Hello,

I am trying to monitor a MS Dynamics CRM 2013 instance using the Performance Counters provided. 

I will be writing VB Script to collect the performance counter data via WMI. 

I couldn't find out the WMI class reference the Dynamics CRM 2013 performance counters.  

What I meant was, some thing similar to the 'Windows Server Cluster' Object and Performance counter class, as given below.

Regards,

Krishna.
