I don't get notification of services unavailability even with hot check disabled, because Nagios does a host check directly after it find a service unavailable. > I personally haven't decided if I will enable host checks.

Not additional if you replace the ping check by the hostcheck Is the impact of enabling hostchecks vs ping service only a status of UNREACHABLE instead of DOWN for child hosts ? -- L.B. ------------------------------------------------------------------------- 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
