Healthy – green check mark

The agent is running normally.

Critical – red check mark

There is a problem on the agent.

Unknown – gray agent. The check mark and agent name are grayed out.

The health service watcher on the RMS that is watching the health service on the monitored computer is not receiving heartbeats from the agent anymore.  It had been receiving them previously (and it was reported as healthy), but now it is not. This also means that the management servers are no longer receiving any information from the agent at all.

The computer running the agent might be down, or there might be connectivity issues. You can find more information on the Health Service Watcher view.

Unknown – green circle with no check mark
