How do I make a simple counter, that show how many of my hosts are down?
We are running heartbeat.
I'd think it was simple to make this, but I can't figure it out.
How do I make a simple counter that show how many of the lastest pings to hosts have returned "down"?
Or can I make a treemap or Donut or something, so I can also know which hosts those are.
This is probably really obvious, but I can't figure out how to make this. Seems like a common use-case.
EDIT: I just checked the server that is down, via Discover, and Heartbeat just stops checking the server when it dies? Then what is the point of Heartbeat? How do I then check if my servers are up or down? I thought that was the whole idea behind Heartbeat? Have I misunderstood something?
