I have some problems understanding how does flapping of icinga2 works.
I found only 3 lines in the documentation about it.
I added the enable_flapping = true line to my host. Then i've been switching it on/off 10 times waiting for icinga to go from DOWN to UP (hard states) but the host state is not flapping. I guest that's because i need to set up flapping_threshold. But what is that? What i suppose to put there? Number of state changes before making the host flapping? What does that threshold represents? I think that part must be explained a little bit better.
