Download Monitor is a simple application which can be used to monitor the amount of data downloaded and uploaded over a network. It displays an easy-to-read graph in monthly, daily, and hourly basis. When you launch this application, you'll see an overview of recent data usage. The overview page tells you about the download, upload, and total usage for the last hour, the last day, the last month, and since monitoring started. If the overview shows zeros for everything, it means you have just installed Download Monitor and there is no data yet.

Viewing detailed bandwidth usage
You can view detailed bandwidth usage monthly, daily, or hourly by selecting the relevant toolbar button or selecting the relevant item from the View menu.

There are 3 horizontal bars: green representing uploaded data, red representing downloaded data and blue representing total transferred data. The vertical bars show the usage quotas you have set.

Setting Quotas
You can also set the quotas and get notified when your bandwidth reach the quotas. Simply open Edit > Preferences and set the quota as you wish:

Download Monitor can be installed on Ubuntu easily by typing the following command:
  • sudo add-apt-repository ppa:duncanjdavis/download-monitor-submit
  • sudo apt-get update
  • sudo apt-get install download-monitor

Enjoy :)
