host event notifications

[Robert.Lattanzi at fitchratings.com]

hello all-
      i have about 50 network devices that i am monitoring. each one is
configured as a host, with the check_command defined as check-host-alive.
in addition, i have a ping of each device defined as a service, with
event_handler enabled and set to "networkdevice-notify-by-epager", a custom
script which dials a skytel paging server and sends directly to our pagers.
the event handler works from the command line (as user nagios) and i get no
complaints from nagios at startup about incorrect or nonexistent commands.
      my first question is, is the ping service necessary? it doesn't seem
as if it is. all i want to know is if each of the network thingies is up.
check-host-alive should suffice, no?
      second, and more pressing, is that when testing all of this against a
"fake" IP address (sure to return a CRITICAL error), neither my host event
handler nor the service event handler gets triggered. The host shows up as
CRITICAL in the UI, but nothing else happens. Moreover, I see the event
handler for the host being called in nagios.log, but that's where it ends.
Below are config file snippets. Thanks in advance, Robert
