bandwidth monitoring (4 algorithms) alerting and graphing
This script monitors your bandwidth usage 4 ways: * local: total monthly bandwidth usage estimate based on data from /proc/net/dev over the last three hours
month: total monthly bandwidth usage estimate based on linode xml over the current month
period: total monthly bandwidth usage estimate based on linode xml over the last three hours
used: actual total bandwidth used this month, from linode xml If any of these goes over a threshold (percentage of your quota) specified by you, it emails you. All calculated rates are logged as gigabytes per month.
The url lists three files:
linodebw.pl - perl script, you need to edit three variables at the top.
linodebw.png - example output from my linode
linodebw.gnuplot - config file to graph the data with gnuplot, you'll need to edit the output and log paths.
I would appreciate feedback.

Update:
Google searching turned up a previously created script by the same name, but since it appears to have vanished I re-used the name.
