Graphing CPU temperature in OS X with Munin

Last week I made a plugin for Munin to collect the temperature of my Macbook’s CPU, hard drive, and GPU, for no real reason other than I thought it would be need to see how they change over time, and because graphs are irresistible.

The plugin is on github. It requires a free app called Temperature Monitor to be installed so the temperature values can be collected in a script (I could not find any way built into OS X to collect the data from the command-line, like you would read /proc on Linux).
