I’ve been searching for some simple tools to monitor my internet connection for some time, and finally I’ve found a few tools that do the trick.
If you’re looking for a console application to give you a quick heads up on the transfer speeds across a network interface have a look for ifstatus (not to be confused with the ifplugd suite) .
If you’re looking for something to log and display network statistics checkout vnStat
Minor niggle: both these programs needed compiling and required additional dependencies which I recall were GD, for the graph creator of vnStat (vnstati) and curl for the console interface of ifstatus.
If you have any other suggestions, queries or points, please leave a comment!
