Hi Chris - can you show me what the report looks like in vCOPS, I'll see if we have anything similar - thanks Danny 
So there is a report in vmware's operations manager called vm guest capacity usage.  I need to somehow dupicate this.  Foglight does not seem to have a vm capacity trending report, just a esxi, cluster and datastore capacity trending.  i need a vm guest capacity trending report.  i am using 6.7.  not sure if something like this added to 7.  i know i can probably try and build a custom report to mimic this but would prefer a canned....
