They may be displayed as CRITICAL, and they are, but no alerts are sent for them. > there is a need to designate a specific dependency check for > services and then it will only "learn" > of the down status . > > Is there a way to tell nagios that once a server is down - not to > check the services assigned to > this server ? to me it seems like this Not really. Nagios is primarily a service monitor and services are central to it's check logic. If a service reports a non-OK state, Nagios will check the status of the host. If the host reports a non-OK state, notifications for services are suppressed but will continue to be checked. The service checks are necessary because Nagios uses them to determine when the host has recovered. Bear in mind that the normal and recommended operation of nagios is without regularly scheduled active host checks. In such a configuration, a host recovery would never be noticed if service checks were disabled. > So once the host is down/unknown/pending , all the services on the > server are not checked and do not > send alerts . Nagios automagically suppresses alerts for services on down/ unreachable hosts already. No special configuration is necessary other than a host check_command that works correctly. Pending status means that no services on the host have been checked yet. No special action necessary there. -- Marc ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Nagios-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
