is it possible to monitor a second network with Nagios? I have a box running as a router being monitored by Nagios, both ethernet ports are being watched.
Nagios is on 192.168.x.x The box I am monitoring is on 192.168.x.x and 10.10.x.x, I have both Ethernet ports being monitored but now I want to monitor a router on 10.10.x.x?
Can the NAGIOS box talk to the router on 10.10.x.x through the other router? If so, then yes, you can monitor it. You would want to set it up so that the first router is a parent to the second as well. I’m assuming that the first router is routing some traffic from 192.168.x.x to 10.10.x.x and that you could allow traffic from the NAGIOS box to pass.
