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,
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
(we monitoring 3390 hosts with 18748 services from one server, latenci
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.

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

I think mod_gearman is what you're looking for:

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

Take a look at mod_gearman for distributing the checks:

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

I do get correct output:
Planar 3.3V = 3250
Planar 5V = 4900
Planar 12V = 11880
Planar VBAT = 2920

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

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
