Centralize 3 Nagios Core on 1 Nagios XI

[asamir69]

Hello everybody,

In my company we use nagios core for monitoring our network. We want to purchase the Nagios XI but we wants to make a not ordinarily configuration.

We want to integrate three Nagios core in one Nagios XI. Each Nagios Core will check actively and monitor its equipment and the notification will be sent by each nagios core for his equipment’s of monitoring.

We don’t want that the notification is provided by the nagios XI
We only want the Nagios XI to centralize the administration of these three Nagios core on Nagios XI and also centralize graphs of the three Nagios core.

Here is a diagram we want to do:

I contact the sales nagios which confirm me that is possible to do. He explains me that will be easy by using 4 nagios XI (no budget to buy 4 nagios XI) and that we can do with 1 nagios XI and 3 nagios Core but its not documented.

Does anyone know how to do this please?

Could you clarify this request? What type of administrative tasks are you looking to perform from XI?

and also centralize graphs of the three Nagios core.

This is very possible. You would configure outbound checks on your core boxes using nsca and a global event handler. This will push the checkresults to XI where they will be rolled into RRD for performance data and will allow reports to be be run against the aggregation.

Thanks for the response.

We want to use the Nagios XI only for administration of the 3 nagios Core and get get graphs and report of the 3 nagios.

The centralize administration; mean for me that we can add the 3 Nagios Core on the Nagios XI. And then by the web interface of the Nagios XI add host check and service check on the Nagios Core we want.

The notification will be done by each Nagios Core.

Could you please tell me how to configure the outbound checks?

Nagios XI wasn't designed to configure remote Nagios Core machines, but it can have the results of their checks sent to it. You would want to look into something like Puppet or Chef to manage the remote Core configs.
