Hi all,
my nagios installation has currently 400+ hosts and around 1400 checks.
As the server load grows, delays are appearing.
Is any way to move a part of active checks to a second nagios server?
And in that case how will these two nagios servers exchange data?
If this is feasible can you poin

Hi,
I have a Nagios 3.2.3 box on an Ubuntu server 11.04 with about 930 hosts
and 28500 services. For each host, I have 5 passive checks mapped on
SNMP Traps. In order to secure those checks, I set up a freshness checks
using check_dummy and a freshness threshold of 15min, as I normally
receive
When I run the following command, to check running it against the nagios
user:
su nagios -s /bin/bash -c "./check_snmp_ibm_imm.sh -H 172.29.13.16 -C
4H2KZNpX -T voltage"
I do get correct output:
Planar 3.3V = 3250
Planar 5V = 4900
Planar 12V = 11880
Planar VBAT = 2920
|Voltage1=3250 Voltag
Take a look at mod_gearman for distributing the checks:

See the documentation on distributed monitoring .
Also check out check_mk and mod_gearman.

What's the spec of your nagios server?
We're checking (around) 500 hosts, 4500 active, 5000 passive service with
Nagios 3.4.1 in a CentOS 5.8 VM with 2GB RAM, 4 vCPUs, without problems with
the help of check_mk /mk_livestatus (http://mathias-kettner.de/check_mk.html)
Also using pnp4nagios and r
Doesn't it depend on how often you're performing the checks too? 1000 checks
every 10 seconds is harder than 10,000 checks every hour.
We have 589 hosts/3619 service on a 2 cpu 2.8GHz xeon with 1GB of ram, which
does other things too. The machine is about 8-10 years old.
The checks are schedule
I think mod_gearman is what you're looking for:
http://labs.consol.de/lang/en/nagios/mod-gearman/
Also 1400 checks is not that huge of a setup. You can also specify
check_interval for certain checks which don't need to be executed every now
and then (e.g. Disk Space Utilization, HDD Smart Status o

Hi,
I suggest to review your installation. Try with the large installation
tweaks http://nagios.sourceforge.net/docs/3_0/largeinstalltweaks.html.
Then, check whether you need all your checks at 5 mins or you can move
some of them to 10 mins pace.
Then, review your check plugins: Perl plugins eat
Also, you might want to find out the performance of your service checks.
The nagios profiler is a very good tool to find execution time of
individual services.

Great advice. Funny you should mention status.dat in ramdisk as we have
hit a hiccup this morning which has meant we have lost comments and
downtimes.
We had moved status.dat to a ramdisk as recommended for large installations

Hi,
You are right., open files IS a major concern I forgot to mention. A quick and
dirty method to solve it is to raise the number of open files putting ulimit
command folllowed by a high value in The Nagios startup script.
ulimit -a will tell The current system wirde ulimit value.
Lucky you,
