Hi all,

We're running tests on our Apache CloudStack (4.19.1.2) environment where
our hypervisors are running KVM. We've noticed that when we pull the plug
on a hypervisor, it can take ACS up to an hour(!) before it finally notices
that the hypervisor is down and changes the state to DOWN and in the
meantime, it considers the VM's that were running on it still available.
This leads us to two questions:
1) which variables need to be tweaked to make ACS notice something like
this in just a couple of minutes instead of more than an hour?
2) why are these values so high? An hour before ACS defines an agent
offline seems very long.

Kind regards,

Jeroen Kleijer
