Missing notifications?

Then just turn a server off and wait a bit...  ;-)  You could also create a
fake host, one with an unpingable IP address.

As for how much time it takes to notify once the host/service becomes
unresponsive, these three definitions (outside of any separate escalation
policies) will dictate how fast the first alert will go out:

  max_check_attempts
  normal_check_interval
  retry_check_interval

In your case, you'd probably want to set max_check to '2' and normal and
retry to '1'.  In this case, assuming "interval_length=60", the host (or
service) would be checked every minute.  When the host becomes
unreachable/down, the host would then be rechecked once, one minute after it
first becomes unreachable/down.  If it was still down, the state would then
become 'hard' and an alert sent.  Total time before alert was sent could be
anywhere from 61 seconds to two minutes, depending on when the host is first
checked after it goes down.

You really need to read the object definitions in the Nagios documentation.
