Playing with Cacti

So I’m looking to play with some monitoring software to figure out why, every once in a while, I get laggy spots when connecting to my server from work.

The latest toy I’m playing with is Cacti.

Here’s what I’m planning on monitoring (partially because it’s useful, partially because it’s fun):

link (Linksys router running dd-wrt)
* bandwidth on external IP
* bandwidth on each port
* wireless bandwidth used
* memory used
* processor used
* uptime

Unicron (server)
* bandwidth used
* memory used
* processor used
* load avg
* spam stats
* apache trafic
* IRC users
* ssh users
* bind traffic
* uptime

Draccus (server)
* bandwidth used
* memory used
* load avg
* processor used
* ssh users
* uptime

Any other suggestions on what to monitor, or which templates to use?
