I got a sample of code up at http://hvdkooij.xs4all.nl/stats/ which you
may want to look into.
You need to get 3 variables to get the actual size + usages.
1 being the unit size
2 being the number of units for the device (partition)
3 being the number of allocated units for the device
Total size = 1 * 2
Used = 1 * 3
This is easily discovered by doing an snmpwalk over a device and dropping
the results in a file. Studying this file has shown me al the nice options
I can monitor.
All email sent to me is bound to the rules described on my homepage.

Don't meddle in the affairs of sysadmins,
for they are subtle and quick to anger.
