I'm not receiving collection data from most of our VMware environment.When I go into vmExplorer all I see all the legacy ESX 3.5 hosts, but they only show very basic info in summary and resources. No data is populated in any of the perfmonce counters below that. None of the other hosts or clusters show up.
Permission issue at datacenter level.
If using domain user group, make sure the user has read-only permission above the datacenter level.
