How to make icinga2 to alarm only 10min+ downtime?

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.
