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
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.

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

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.
We use rhel 5.x, so the perl is 5.8.8.
We have semi dailoy updates to our pollers

How do you mean that you're losing capacity? Does latency start to creep

Over what period of time?
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

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.
