Time until notification

Wondering how I configure Nagios to notify me quicker than default? Have a default install, and if I take a host off the network, it takes Nagios 12 mins to notify me.
Have tried playing with checks settings, number of checks, etc but can’t find how to get it to notify me sooner…

Thanks, John.

retry_check_interval multiplied by the number of retries… is the minimum time it can take… reduce the retries… or the retry interval… don’t go to 1 and 1 as it would get probably a lot of false positives.

Thanks for that.
Slowly working it out… :smiley:
