[Nagios-users] high latency

Yeah, for giggles I went back further through the archives last night
and found stuff back to 2.x series, and not much has seemed to help.  I
killed some of my mis-behaving active checks, and that dropped to about
20 seconds, then went up to about 35-50.  So while that's better, I have
A LOT more hosts and service checks to add, and am afraid it'll go nuts
when I dump more on.  I think I've tried about all the config options I
could find and some helped, some didn't seem to, but  there should be
plenty of horsepower on the machine to run this much faster so not sure
why it's not.

dan 

there were a couple of discussions on the list that dealt with latency
issues .

Have you tried looking at the list archives about the topic ?

I've been watching my latency graphs, and showing 2000 seconds for some
service and host checks.  What I don't understand is I still have idle
time on the CPU, (quad processor) so I'm curious if the server isn't in
trouble, why am I seeing such high latency?  Or maybe I misunderstand
how latency is calculated?  I do have 9 service checks that are failing
on about 700 hosts if that matters at all.  Trying to tweak the
performance to the max on this so any insight welcome.

 

Thanks,

Dan
