We recently discovered that we had a cluster of hosts (VMware) that was not reporting any sort of utilization data to VMAN even though all of the other hosts in managed by the same VMAN server were reporting data. We didn't discover this until after the hosts were patched and rebooted (causing issues) and we went to look. The data was being collected post reboot, but nothing before.
Request: Provide a way to determine if a resource (host, cluster, etc.) has not reported data to the DB within a specific period of time. As per support there is currently no way to build this alert right now.
