Try check_cluster. Check_cluster aggregates the status of individual ESX
hosts. The clusters here have three or four ESX hosts each. If one ESX host
in the cluster is offline, my check_cluster returns a warning. If all but one
are offline, I have it return a critical. At that point, the engineers have
more important things to worry about than individual guests.
I have a fake "host" for each cluster whose check_host_alive is the
check_cluster command. The guest VMs on each cluster have the fake host set as
their parent. The guests can move around all they want and I don't have to
change anything.
When the engineers change the clusters by adding or removing ESX hosts, all I
have to do is add or remove one ESX host check and update the check_cluster
command. I don't have to edit the list of parents for all the guest VMs, which
is important, because we have more than a thousand of them.
