the link represents a good thought process and helpful info for CPU waste, but I still don't see anything that would indicate what virtual disk waste in vCOps actually is. I have a VM with an 80GB disk. There is right now 20GB of data on it.
I go to operations -> All metrics and select a virtual machine. Then I go to:
Waste -> Disk Space ->Total
How did that figure get calculated with what mathematical formula?
