We graph the results but not after every check. I use the performance output
to pool it to a file first .

another possibility, do you use addon to do task after "every" checking?
for example, update RRD files for performance graphing, sometimes that
should increase the checking latency.

Hello All.
I would like to get an advice with nagios latency issue.
In nagios 3.0.6 with RHEL 4, would there be a possibility
that service check latency hikes even though the sar or iostat
usage is not in relatively high load usage? (I am planning to upgrade to v
3.2.3 soon.)

If they're very deep, it's possible. Otherwise it really shouldn't matter
all that much. It will ofcourse add *some* load, but it shouldn't be enough
to cause latency.

Latency increases much more quickly for us without epn as execution
times are noticably longer per check.

I too struggle with them and I'm running on lightly-loaded physical hardware.
We have 2 servers doing the checks sending back to a central server. Both

Sorry for confusion on that..I added 9 checks to *each* host, and
there's about 700 hosts. No, it's all the nagios daemon itself (nagios

We have semi dailoy updates to our pollers and with epn that means

Not using SNMP for any of the checks, and most are passive checks. For
the few active checks we are probably going to be using dnx.
Embeded perl is interesting though, I hadn't tried that, thought

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
Could it be that the more service check I move off the main Nagios
server an on to the tested hosts to run via NRPE , that the Latency will
increase ?

I am having a problem with very high latency on my main nagios server

I recompiled the core with the embedded perl and that helped for a
