I finally decided on a network monitoring solution for the campus. I decided to go with Zenoss since it handled auto discovery pretty well and the stack installer was really easy. I also tried zabbix and cacti. Zabbix has an installer script that is also wonderfull. I think Zabbix came in second for me.
I also got a Snort IDS setup on a monitor (span) port as well as NTOP. It’s been running for less than 24 hours and it’s already given me a good look at how much junk there is going accross the open wireless network and student networks. Thank god for 802.1x and vlan assignments. 🙂
I’ll probably scale it back to just the employee network and lab computers since we are not allowed to lock out student computers.
