Sometimes it happens that the cpu and memory usage of individual ESXi 5.0 hosts will not be available in the vCenter:
Solution (respectivaly a workaround):
In this case a restart of the management agents will help to solve the problem.
Just login to the console and press F2 “Customize System/View Logs” to switch to “System Customizaton”:
Now select “Troubleshooting Options” and then “Restart Management Agents”:
It lasts about a minute till the data will be presented in the vCenter as usual.
Thx for this post! After an update from vCenter 5.1 to 5.5 the vCenter-VM and several other VMs stopped reporting performance data and the Real-time-option was missing in the “Performance-Advanced” menu.
After reading this post, I realized that one host had the issue described above. “Restart Management Agents” solved the Problem.
Thanks.
Will this process effects normal working of VMS on Host
