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.
