a customer reports problems with statistics of virtual machines on one of his four ESX 4.1.0 (260247) Hosts. The Statistics show the VMs up and running, turned on, status "normal", they show the diskspace, but they dont show up host-cpu, host-mem and guest-mem (these values are all zero). This Problem has appeared some days ago and didnt go away by itself (so its no temporarily issue).
The problem shows up when connecting w/ vSphere Client to both - the Server, and the single ESX Server.
Any recommendations on where to dig what the problem might be causing?
Perhaps restart the management agent?
service mgmt-vmware restart
Do the VMs show with stats if moved to one of the other hosts?
