Flapping VMWare Tools detection


I have a strange behavior with the detection of VMWare Tools. Check_MK displays state change alerts frequently detecting VMWare Tools.

The VMWare Tools is installed on all machines, so I don’t know the reason for these messages. Has anyone happened something similar?

These alerts are from the same host

Thank you

This is not a problem with the agent - this is a real problem in your VMWare environment.
The host or the vCenter don’t know the right status of your VM’s. Better said it cannot communicate correctly with your VM’s.
There are many possible reasons. Like VM is only configured with 1 CPU and a single process is blocking the parallel execution of some processes. High load on the VM in general.
You find many more on the net.

Thanks Andreas-doehler, I will follow your advice and search within VMWare
