nagios master slave configuration

[pkrk]

Hi,

I would like to install nagios in 1 server and have 2 other servers, as slaves from the master.

Do you know how can i do that?
is there some tutorial?

It depends on what you mean by a slave. Can you expand on what you are trying to do?

I pretend to do Master server in one server,
then having two slaves server , 1 for linux hosts and 1 for windows hosts

Most master/slave setups I've seen are using passive checks to pass [slave check results] up to the master server. The setup will require some Nagios knowledge, is non-trivial, and doesn't have nice neat HowToForge style step-by-step instructions (to my knowledge).

Refer to the "Federated Monitoring" section of this document for pretty pictures and high-level overviews:

Some more resources on passive checks:

NRDP is a very common tool used in such setups:

In this setup, the "master" Nagios XI server acts as a bucket of sorts to collect all the results from the slave Nagios Core and Nagios XI machines.

Thanks @mcapra!

@pkrk, did you have any additional questions?

[pkrk]

what about Mod-Gearman ?

or other load balancer solution with 2 nodes of nagios sharing the load?

Mod gearman is possible as well, here is a doc on utilizing that
