Nagios Support Forum

I have been trying to understand the actual mechanics of flap detection. I know that this is based on the percent of time that the service goes up and down. But what time window is used? Can this be tuned? I cannot seem to find this explanation in the documentation.

Someone has got to know where this information is. Anyone?

Check your nagios/etc/nagios.cfg file for the settings:
I don't know for sure if those units are are minutes, or what exactly they're expecting, but that'd probably be the config to edit.
