Monitor Network Usage With Download Monitor

 

Download Monitor is an application developed for the Ubuntu Apps Showdown, useful for computers with a limited Internet plan.

The application displays the monthly, daily and hourly amount of data transferred over the network and it can warn you using desktop notifications when you're about to exceed the usage quota, which you can set from its preferences.

Download Monitor integrates nicely with Unity by using dynamic quicklists so you can see the network usage with a click and also, there's an Unity Launcher progress bar which displays the used / remaining usage quota:

Once the Ubuntu Apps Showdown is over, Download Monitor will be available in the Ubuntu Software Center but if you want to install it already, you can use the following commands:

sudo add-apt-repository ppa:duncanjdavis/download-monitor-submit
sudo apt-get update
sudo apt-get install download-monitor

For other Linux distributions, you can get Download Monitor via Launchpad.
