Nagios Server Redundancy Design

Post by gamal »

Dear All,

1- if we are going to Design Nagios Server with Redundancy,"Active-passive" Nagios servers,can you provide me with Docs for that ?

2- do we need centralized remote probes, to collect monitoring data and sent it to the Nagios server.

BR,

Not really -- those docs don't exist. Nagios XI has some limited high availability documentation:

I've done hot/cold setups in my lab environment with Chef, the nagios cookbook, and some clever wrapper cookbooks. You could architect a similar system around foreman if you already had the config distribution figured out (via etcd perhaps?).

You have the option to distribute your "probes" and collect them in a central Nagios Core location via passive checks.

Unless I'm misunderstanding the question, a "need" for such a setup would depend on the topology of the network on which the hosts reside more than anything. If your single Nagios Core server can reach all the hosts, it can execute active checks against those hosts directly and you can just as well centralize the probes.
