I've actually checked Nagios 4 now, and it appears we don't do this there.
I didn't test it all that thoroughly (and I probably should), but it's
friday and I'm two beers past my best-before-thinking hour, so I'll just
refrain from trying it further today.

What you propose sounds acceptable.  In the meantime  I need to be careful
about reloading nagios :).  Once I get it in that state, I have to disable
use_retained_scheduling_info and then do a full restart.

This should be pretty easily fixed by just adding a check reaping event
before initializing the event queue and skipping all checks that have
already been scheduled.

I'll have to add a check for it in 4.x. Since we keep workers between
reloads, the same thing can easily happen there.

That means we'll reschedule all checks like normal when we're starting,
but if a check result comes in when a new check is already scheduled,
we'll remove the old event and reschedule a new one according to the
retry interval. I'd suggest doing something similar in the 3.4.x
branch, but I'm not sure I can commit to that one without doing a new
svn clone, and that takes at least a day.

Mark; Would that be acceptable to you?

Oh, and good catch :)

I think I found the issue.  If I happen to send a reload (HUP) to nagios
while a service check is in progress (fairly easy since my service check is
rather long lived), the reloaded nagios doesn't seem to know about that
service check and so I'll end up with another being scheduled as well as
the original on its schedule.  Create a dummy service check that just
sleeps for 30 seconds or something and issue a reload while it is running
and see if your nagios instance will start another sequence of service
checks.

There isn't a second nagios instance.  While I was watching the pollers
spawn, they all led back to the same master nagios instance.

Re: [Nagios-users] service checks running too often

2012-12-13 Thread Mark Keisler 
I understand that nagios dynamically adjusts service check times, but the
puzzling thing is that there is a check that runs every 5 minutes but then
an extra or two in between.  And yes, the web interface shows the next
service check as 5 mins out and yet another runs before that time hits.

Re: [Nagios-users] service checks running too often

2012-12-13 Thread Mike Guthrie 
Although some of those start times do seem close together, it's 
important to know that the check_interval in Nagios is not necessarily a 
hard number. Nagios is continually adjusting and recalculating the check 
schedule, so if you need a check to run on a hard 5mn schedule, you 
might be better off using cron, and then pushing the result to Nagios 
passively.


With that said, access the service details for this service. When new 
results come in does the scheduler set the Next Check 5mn out as expected?

[Nagios-users] service checks running too often

2012-12-13 Thread Mark Keisler 
I'm running Nagios 3.4.1 on RHEL6. I have an issue where I have a poller
(service check) that is running too often and I am not sure why. I have
"service_check_timeout=180" because I had trouble with the poller running
long. Relevant settings for the service check:

check_period24x7
max_check_attempts  1
normal_check_interval   5
retry_check_interval5

I also set up a tracking logger in the poller to record "timestamp PID
started by PPID : Poll [Start|End] of poller"
