I notice the Fusion Pro product page shows CPU/memory/etc. stats at the bottom of an ESXi server:
And the help, too, suggests this feature:
"You can view the power state, CPU use, and disk space use of a server or the configuration information of a remote virtual machine by selecting it in the Fusion interface."
"Select a server to view the CPU use, memory use, and available storage.
The CPU use, memory use, and available storage appears at the bottom of the interface."
However, I never see that bottom pane. I do see Snapshot/Configuration File/Hardware Compatibility on individual machines, but nothing on the server, whether I connect to a vCenter or directly to ESXi, in both cases 5.5.
