How does the data look? Would you be able to create an instance per VM then do math on when the last snapshot was taken compared to the time of poll? Then you would have something like

I'm sure that Could be done.  But I have no idea how to do it.  ;)  The one I have now works, even though it doesn't work 100%.  It works enough to throw an alert if a Snapshot age goes over 3 days.  Then I can just go look at the error to see which VM it is.

I don't know how to create DataPoints.  The only reason I got as far as I did is I was copying a different one and tweaking it to try to get what I needed.   Since VMs are stored on the HPV Hosts, I thought the instances would be the Hosts and then it'd be able to put the VMName in the Raw Data.  But since it's Text, I guess that won't work.
