I am looking for some help creating a report of all my virtual machines and the change in size of data on the drives of each vm.  I have looked at several of the canned reports that are available but it appears as though the weekly growth is based on an average of the last three months.

The VM's created report tells me that there were some new VMs created in the last week but it doesn't show me the names of the machines and that is something that I would like to know

Any help is greatly appreciated.  Thanks.
