That would explain a lot of the scheduling weirdness, maybe all of it. :-) > Is anyone else seeing weird things in the scheduling of checks? I don't have a good sense of what is wrong but, it's definitely not the way it was under Nagios 1.0 (or the way it should be). I've been watching the scheduling queue on our Nagios 3 box for a week or so, here's a list of what I've seen: > Under Nagios 3.0.6: > - host checks staying at the top of the queue for a long time (over an hour sometimes) even when they have a timeout set at 30 seconds > Under Nagios 3.1.6 > - host check showing up unexpectedly in the scheduling queue, this morning when I looked at the queue the top event was about 15 minutes behind the current time but things were moving along okay, when I last checked there was a host check at the top of the queue with a next check time from 4 days ago. > - We had a host go down yesterday (Sunday) but we did not get alerted. When I looked at it in Nagios I noticed the host check was in an OKAY state and the 'last check' value for it was from 12 days ago (6/17/2009)! > - Host checks don't seem to be getting stuck in the queue like they were under 3.0.6, at least not for as long > I'm going to submit a ticket to tracker.nagios.org but would like to have more empirical evidence of the problem first, all I have so far are symptoms, no good data points (logs, errors, etc.). Is anyone else seeing this type of behavior? > Nagios 3.1.2 (also had trouble with 3.0.6) > RHEL 5 64 bit </BODY></HTML>
