Playing with Cacti

By Jesse Morgan | April 12, 2007

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?

    Personally I always like to see disk utilization, disk space used/free space.

    Not that familiar with Cacti but if you can get it to be where you send your SNMP traps it should be able to alert you on things like errors on the NIC, hard drive failure in a RAID array etc.
    Sorry can’t be much more helpful than that, it has been a long time since I worked with Cacti.

    yup- I was just trying to add disk utilization- instead I ended up ripping out half of the default templates so I could learn how to better do it myself.

    It does have full snmp support as well as being able to fire off perl scripts and parse returned data.
