I am having this issue with my Vmware server. I can get hardware status when I log into the Vspear client to the VM Server itself, but when I log into the VMWare VCenter server and check hardware status I get this message
"No new host data available, data will be updated in 5 minutes." When I hit update I get a little popup that says "Host sensor data is not updated. The Query Service is not available or was restarted, please retry"
I have tried this "kb.vmware.com/kb/2011871"
and no luck as it describes a windows version of vcenter server. I am using the Vcenter appliance as a VM on my server.
also this, kb.vmware.com/kb/2015838
I currently have a VMware server ESXi 5.0 r1 , with Vcenter Appliance Version: 220.127.116.1194 Build 920217
Both VM servers are Dell R510's
