If some of the monitored servers is down, ISPConfig Monitor shows that but seems to not notice when I get it back to running. I have to stop ISPConfig monitor and start it again to see the current situation. Docs say there is one minute delay for the monitor, but I have left monitor running and it seems never to notice server should be green now. ISPConfig monitor version 2.1.2 (latest from Android Store). on Android 4.4.3.
