Log Broadband Use (Three.ie)

Mobile broadband is often the best we have and is mostly reliable and fast enough - however over quota charges are horrendous. It is important to keep track of usage and remaining data allowance. There is no automatic way to do this on Linux, especially on a network used by multiple machines.

Three provides a web interface to latest data but it isn't always convenient and doesn't record a usage history - essential for tracking down extraordinary usage problems.

This simple script presents a solution, accessing the data from my.three.ie - storing the quota remaining in /var/log/threebroadband.log. Add it to /etc/cron.hourly as "threebroadband". I like to use Wanda-the-Fish on the Gnome panel to be able to quickly check on usage (add the custom command "tac /var/log/threebroadband.log" to the preferences instead of "fortune").

#!/bin/bash
# Check Three.ie broadband limit remaining.
# See /var/log/threebroadband.log for results (or add Wanda-the-Fish to the Gnome panel with the custom command "tac /var/log/threebroadband.log"
# Run automatically ever hour by adding to /etc/cron.hourly as threebroadband
