Hi Everyone,
I was wondering if anyone has had a chance to run the event profiler on the=
ir system and see what comes up?
The reason I ask is that after running the event profiler for a while here,=
I've noticed, that at least on my setup, upwards of 70% of the time is spe=
nt in the reaper.
Admittedly this could be due to a misconfiguration on my part, but changing=
the service reaper frequency from 3 to 15 made things worse.
My Used/High/Total Check Result Buffers: are 264 / 622 / 4096 respectively.
My avg time per event for the reaper is 3.26 seconds it went up to 10 secon=
ds when the frequency was set to 15.
My hunch is it probably would have been longer but there is the reaper bail=
out after a certain amount of time.
However I'm using DNX and DNX writes directly to the circular results buffe=
r, so the question is...
What are the odds this is a problem with lock contention, or is there a mor=
e likely candidate.
Also I'd like to extend the event profiling metrics to find out for sure wh=
at's consuming all thing time, but before I do I was hoping someone more ve=
rsed in the internals of Nagios could point me in the direction of what wou=
ld be some good next things to measure.
Even so, if someone could please run the event profiler on their system and=
see if your getting similar results that would be a HUGE help.
Thanks in advance!
Sincerely,
Steve
