Nagios Service Check Suppression


Nagios: How to suppress notifications when host goes down.

There are two ways to avoid extra notifications of services when host goes down.

1. Configure ping (use check-host-alive) as the host check, when the host is unreachable, the notifications for the services will not be sent.

2. Can have service dependency configuration file like this,
define servicedependency {
hostgroup_name all_servers
service_description ping check
dependent_hostgroup_name all_servers
dependent_service_description *
execution_failure_criteria w,c
notification_failure_criteria w,u,c

Problem: This should be built into the very core of the software! I assumed it had been. I've learned otherwise.
