To have nagios wait 15 minutes before doing anything at all, put this in
your service definition or template:

max_check_attempts              5
normal_check_interval           5
retry_check_interval            3

The service will need to be down for 5 checks at 3 minute intervals
resulting in an approximate 15 minute delay before notification goes
out. You can also to it with escalations, just set your
first_notification to whichever contact attempt matches your timing you
want based on your notification_interval defined for your service.
