We have some flapping services. These change rapidly from “OK” -> “Warning” or “OK” -> “Error” and then back again. Every of these changes generates one mail. About 500 Mails a day. Too much.
Any idea how to prevent services (or hosts) sending such mail if they are changing state just every few minutes? Can this be done automatically? Making check_mk detect flapping services and then suppressing any mail if states change or even better: automatically changing deadlines mails are generated?
Delay service notifications, 10 minutes
Delay host notifications, 9 minutes

You can do both: disable flapping for hosts or services or you can even prevent flapping events from sending notifications.
Personally, to cut down on noise, I prefer to disable flapping for specific hots/services that are problematic.
There is a whole section dedicated to this type of stuff (enable/disable flapping detection for hosts/services, Notified events for hosts/services etc);

WATO → Monitoring Configuration → Notifications
Whole section? I could find “Notifications Configuration”, but not “Monitoring Configuration”. Within “Notifications Configuration” there is nothing except “Trottle Notifications” to configure. And this, I’ve already tried, does not help in any way.
