Odd vCentre issue – Not seeing any performance data
Just thought I would share this little oddity that I found on one of our ESXi hosts the other day. It’s a 5.1 host by the way…
I noticed that two of our host were warning of high CPU usage which was not the norm. Looking a little bit closer I noticed that DRS had been busy moving VMs and had left one node devoid of VMs bar a couple of low use servers.
Again, it seemed odd as there was evidence in the logs that a host had failed. Then I noticed this on the summary screen.
No performance data at all! How odd, I continued my digging.
The next thing that I noticed was that none of the VMs were showing any stats. I should add that the VM below that is showing stats was vMotioned from a working host. Odd that its stats show up ok.
I fixed this issue by a simple management agent restart. I must confess that I didnt have time to get down and dirty with the hosts logs to see if there was a cause. But what I can say is that I have noticed we have to restart the management agents more often since running 5.1. Has anyone else seen that?
