I must be blind but I can't seem to find a way to report on thin provisioned VMs. I am looking to generate a report of what the virtual size of the VMDK is and how much VMFS space it is currently consuming. I can find lots on i/o performance, but very little on space consumption.
That's what the Current Size (GB) metric does while the allocated size is Provisioned Space for VM (GB). You can use these metrics to build that report, or just clone an existing view which has them, edit it, and drop it into a new/existing report.
