I’m trying to speed up the time Nagios is taking to “converge” on a problem host.
I’m using the “execution_failure_criteria” feature (in both the service dependency definition and host dependency definition) to prevent service/host checks occuring on hosts where the parent host is down. I’m doing this in order to avoid Nagios checking for services/hosts that would not be available.
This is working great - in that it is correctly preventing unnecessary service checks from taking place and the problem host is being identified quicker.
However, because the check never takes place, the child service (and host) are always marked “OK”. It would be nice to be able to mark these as “unreachable” as soon as the parent host becomes unavailable, as indeed does happen - eventually - when all the child services/hosts are checked.
Anyone else doing or trying this kind of thing? (Running Nagios 2.0b3 by the way).
Thanks in advance.
