Historical running VMs count

I was looking into creating a simple historical report of running VMs in a cluster....and I realized that there is no such counter, when running get-stattype -entity (get-cluster mycluster), I get the vmotion counts, register/unregister, poweredon/off but no running VMs. Has anyone tried to run a script to that effect?

The amount of VMs, in different states, in a cluster can be found using the vmop metrics.

For example

Get-Stat -Entity (Get-Cluster MyCluster) -Stat vmop.numPowerOn.latest -MaxSamples 1

LucD, thanks, I actually was looking at your post http://www.lucd.info/2009/12/30/powercli-vsphere-statistics-part-1-the-basics/  when trying . The vmop.numpoweron.latest reports the total number of poweron operations , not the number of running VMs at a given time, it seems.

Yes, you are absolutely right, that is the number of powerons that occurred.

Afaik there is no metric to give you the historical number of VMs in cluster.

Sorry about the confusion.
