Interesting observation…VM Processor %Processor time is consistently double that of the Perfmon native Processor % Processor Time counter

What do you think accounts for the difference, VMKernel overhead,CPU Ready or something else?

While it gives people the same feel with the tools they know of in a guest, the limitation you point out are a result of the fact that it is difficult to provide a heterogeneous solution within the guest. So from a performance management perspective, it may be better off to approach it in a top down fashion and go to the guest only if absolutely needed. And for most of the times, an overall performance number from outside the guest would suffice IMO.

Nice overview of the new Perfmon integration.

I suspect that the typical admin of any hypervisor platform does not fully understand the implications of in-guest monitoring.

Reinforces the point that there is more to “managing physical and virtual” than just treating VMs like physical boxes.
