Maybe make a new view with top 10 lists of cpu , mem etc and then use filters to chop it down to only your ESX boxes by say name or vendor possibly.
Good suggestion - I just made one with the VENDOR filter and it looks great.
I wonder if another could be made for just GUESTS systems? Any thoughts on that one?
I do have a Custom Node Property I guess I could use - I don't know the FILTER syntax just yet...
