I am thinking about moving from nagios to icinga. the main issue I have with most monitoring/alert tools:
We have a Render-Farm (CGI). So when there are “jobs” lots of hosts are supposed to be “up” with there services avaible. If there are no jobs the sames hosts should be down and only that is a “ok” state.
In nagios I always had a dashboard with e.g.: 163 “RED”-Hosts with state “Down”. I only managed to supress alert emails depending on the job list (by setting the maintenance flag). Two did not shut down due to some problems (mostly ACPI) and where green and one should be “up” and was not.
So I realy need to set dynamically what is “OK” and what not. Can ICINGA do that?
