I've installed Nagios on all 3 of my Ubuntu 12.04 Servers. I monitor them from my Ubuntu 12.04 Desktop (or any computer with a browser). But in order to monitor all 3 of them I have to open 3 browser windows with http://<ipaddress1>/nagios - http://<ipaddress2>/nagios - http://<ipaddress3>/nagios. I tested out NRPE with another system and got it running on the 'monitored' Nagios machine. But when I look at the browser page it only shows my localhost. Not the 'monitored' machine as well.
For my set up here is there a way to monitor servers 1-3 on the same Nagios browser page on my desktop? I keep getting routed back to NRPE but it seems more like I'm just getting access to whether or not NRPE is installed on the remote machine...rather than actual data feedback from the remote machines. I hope that explains it well...I want to be able to monitor 3 servers running Nagios on one browser from my desktop using the convention http://<ipaddress 1-3>/nagios.
