Better Disk Monitoring with Ganglia

The default disk monitoring module for Ganglia (moddisk.so) is pretty stupid, since it simply sums up the free disk space on all of your disks and presents it in a single graph. Frankly, this just doesn’t tell you much, so I wrote a more useful replacement:

This module reads a list of mounted file systems from a file (probably /proc/mounts) and creates a metric for each one, allowing you to graph disk usage for each file system separately. Enjoy!

Update: It appears that multidisk.py does the same thing, and is probably already included with your distribution. Oops! ;-)
