Binary package “nload” in ubuntu trusty

realtime console network usage monitor

 Nload is a console application which monitors network traffic and bandwidth
 usage in real time. It displays the total amount of data that has been
 transfered over a network device since the last reboot, the current bandwidth
 usage, and the minimum, maximum, and average bandwidth usage measured
 since it started.
 If the user wants, it is also able to display two bars, similar to progress
 bars, presenting the current load graphically. Support for displaying several
 devices simultaneously is included.
