Network Monitoring Advice

[duff-man]

Hi All,

We currently use Nagios Core 4 and NSClient ++ to monitor our primary network, we would like to extend this to another network based on the diagram attached. The network is not directly accessible from the Nagios host and all data must be proxied through a host in a DMZ.

I have looked at MNTOS but am not keen on the interface; I have also had a look at NSCA but am not sure if this is the only feasible option (using passive checks to pass the check_nt commands between Nagios and the hosts to be monitored) or if there is a better method out there. -- not sure if active checks would be better?

At the moment purchasing Nagios Fusion is not an option.

Many Thanks!

My favorite option for a setup like this would be to use mod_gearman to distribute the checks appropriately.

Using mod_gearman, you would define a hostgroup for your second location - call it LocationB. You would stand up a linux box at your remote site with mod_gearman installed, and configure it to handle all checks for LocationB.

This means that any time Nagios Core (your primary server) would process a check for a host belonging to the 'LocationB' hostgroup, the check would instead be handled by the remote mod_gearman worker.

Does that sound like a solution that might work for you? You can read further about mod_gearman here: https://labs.consol.de/nagios/mod-gearman/

Just having a read of this and this seems like something I will need to implement soon. Thanks jolson for the heads up.
