Tiny Networkinterface Monitor (TNM) was written to practice bash scripting. It's analyzing any interface usage (I used it for my DSL connection) . I generates a pseudo graphical representation of the receive and send usage in % of the interface bandwidth an usage in KBs .

 

Download the script from here in a local directory and customize it to the local environment. The parameters to customized are marked in the script.

Adapt the following parameters:
 
1) max transmission speed in KB/s
2) max receiving speed in KB/s
3) Measurement interval in seconds
4) Scrren width in number of chars
 
Invocation without a parameter or any parameter. If a parameter was passed th max xmit and rcv speed is not used to calculate the bandwidth.
