Large scale installation

[Randal, Phil]

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 rrdcached and ramdisk for checkresults.

Large installation config tweaks, and tuning the check result reaper frequency all help even out the load.

Cheers,

Phil

Subject: [Nagios-users] Large scale installation

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 point me to some documentation?

Thank you
