I wanted to clear my concept of infrastructure monitoring. Today, I noticed that one of the servers went offline at 10:30 AM and came back at 10:54 AM.
In the hosts' dashboard, one was grayed-out and other was active.
The downtime/offline time was 24 minutes but we can see that the offline time of the unavailable host keeps increasing even though the server is available.
Also, there is no connectivity on the graph between offline and uptime with the unavailable time.

If you have new host not old one back active this means that agent was reinstalled all even host recreated. We have the same issue with AWS deployments where hosts are destroyed and started again. Right now there is no option for linking them for continuous data set.
Data are missing because during blank there was no monitoring at all.
