Nagios Support Forum

I'm fairly new to using Nagios Core, but I have successfully setup my nagios monitoring server, and from following the quickstart guide within the documentation, I have successfully got 1 server at a remote site up and running fine using the NSClient++. The problem lies with the fact that 1 client I am wanting to setup active monitoring for, have 7 servers, all behind 1 IP. From what I understand of NSClient++ you can only monitor the server that it is installed on to and not others within the domain.

What would be the best solution to be able to monitor all 7 servers with different sets of service/process that I would like to monitor?

Thanks in advance.

You have a few options available to you.

1. Install SNMP tools on those servers and passively monitor instead.

2. A neat little feature (or a way to make your monitoring infrastructure a nightmare to manage depending on who you ask) of NRPE, one of the NSClient++ components, is the ability to use one host as a relay/proxy for others.

If you look for the heading # REMOTE NRPE PROXY COMMANDS in NSC.ini there's an example... unfortunately I don't have any of my own as I've never attempted to set it up. That said, it's pretty straight forward anyway
