I misremembered. I thought there was a network monitoring solution in the huge 12.0 appliance library. I'm sorry if I'm missing it. I've been looking for something to monitor and management the ridiculous number of servers running in our laboratory. Some are mad science; others are kind of vital.
Observium is an autodiscovering PHP/MySQL/SNMP based network monitoring which includes support for a wide range of network hardware and operating systems including Cisco, Linux, FreeBSD, Juniper, Brocade, Foundry, HP and many more.
It's distributed via svn; installation is a breeze (there's an additionaly note for squeeze). I'm imagining a patch solution for it, and it's not really overtaxing me. It's a standard lamp patch. The cypto-inithooks are no longer so crypto. So a turnkey solution for the web app is just a matter of being able to create and admin user in the sql file and then setting a proper password for it on first boot.
The installation instructions are here for Ubuntu and Debian5/6 are here: http://www.observium.org/wiki/Ubuntu_SVN_Installation. In all honesty the install directions are so good I don't suppose there's a need for build notes.
Anyone have experience with observium?
