Nagios Support Forum

Hi,

I have several servers (hosts) in a local network and I want to monitor them with a server (supervisor) which is not in the local network. For some reasons the communications can only be from the hosts to the supervisor. Is it possible to use Nagios for the monitoring ? I tried to use snmp traps but when the supervisor received the traps they all had the same ip (the ip router) and I couldn't know which host was in trouble.

I read the Nagios documentation but I'm struggling to find how to monitor my servers, it seems every solutions need communication in both ways (between the supervisor and the hosts).

How can I proceed ? Is Nagios helpful in my case ?

Thank you.

You can utilize NCPA and a passive monitoring strategy
(The target on local domain will send to the external server)

This will require that you have NRDP enabled and properly configured on your Nagios server.?

Thank you for your answer, i'm using NRDP and it's working well.
