Intelligent way to apply MANY service dependancys?

[Ray Ward]

Hi, I have been using Nagios for a long time but have just switched to
Nagios v2.0b3 and I'm re-working my config files a little bit. A large
portion of my monitoring is done via the NRPE plugins. And a large portion
of the NRPE checks are common across all of the machines. So my structure is
as follows
I have all of the Sun servers in a hostgroup SUN-Servers, I have
definitions for about 8 common NRPE checks that are assigned to the
SUN-Servers hostgroup. So far so good, with very little in the way of
definitions I have 100's of checks defined. Now to my problem, I would like
to define a service dependancy for all NRPE services to be dependant on one
check_nrpe_daemon check. So when the daemon is down I don't receive multiple
alerts for every NRPE check. So I'd like to get the equivalent of this:

define servicedependency{
	dependent_host_name             DBDEV
	dependent_service_description   / Root Slice
	host_name                       DBDEV
	service_description             Check NRPE
	inherits_parent                 1
	execution_failure_criteria      o,w,u,c,p
	notification_failure_criteria   o,w,u,c,p
}

For every common NRPE service for every host in the SUN-Servers group. Now
if I use the SUN-Servers hostgroup in the servicedependency definition it
makes every NRPE service dependant on EVERY host's NRPE Daemon
this
obviously isn't what I want. The best solution I have to this problem is to
NOT send notifications for UNKNOWN service checks for every NRPE check
except the daemon check. But I'd like to know if there's a better way to
apply service dependany's in this situation. Thanks in advance for any help.

PS. Below I've included the relevant entries for one host/NRPE check
definitions.

Ray,
