NagiosXI core and database in separate servers

[grayloglearn]

Hi Team,

I got frequent question like how we can make separate the nagios in different servers such as core in one server and database in one servers.Can someone help how to separate the both.

And how we can make load balancing between both nagiosxi servers for more checks. If you have any document could you please share this too.

Hello @grayloglearn,

If you'd like to offload your database, please see the step-by-step guide below.

And how we can make load balancing between both nagiosxi servers for more checks. If you have any document could you please share this too.

As far as load balancing for more checks, you can either setup passive checks ( requires less resources than active checks) or offload processing to Mod-Gearman workers ( the downside being added complexity ).

Take a look at the documentation and let us know if you have any specific questions.

Hi Team,

Thanks for the reply, As we know that we are installing the database in separate server , I just want to know how about core how we can skip the mariadb installation while we installing the nagiosxi in centos7. Then only we can install the core in separate server right?

Can you tell us how to go install core in separate server.

You need to let it install the database when you first install Nagios XI because you are going to need it to follow the instructions here
Nagios XI Offloading MySQL to Remote Server

Once you have the DB successfully offloaded you can stop the DB service on the Nagios XI server.

This document was awesome. In a single steps without problem i have enabled it. I am getting the same error as ping: local error: Message too long, mtu=1500

How to resolve this, I have not done any nic bonding. Could you please suggest.

What command is being run for that output?

It seems like this is unrelated to the database servers and should probably be in a different thread
