I have the problem that the connection between the host running icinga2, and between the actually checked server machines, is a little bit... non-deterministic.
Thus, sometimes - every day for some minutes, in an unpredictable time - all the hosts and services seem went down by the icinga.
I don't want it. I think the best solution to work around this problem, if I could somehow set up a minimal downtime length, for example, 10 minutes.
Alarms should be created only if a downtime is longer as this value.
The obvious side-effect (alarms get this delay + lack of monitoring for the short network downtime) is not a problem for me.
