Some time in the past, i came across a siple tool that showed live in a 1sec interval, in human readable format, the bandwidth utilization seperated per tc class on your linux server. Unfortunately, i don't remember the name of this tool, and i did not find anything similar. Maybe you know a command line tool that can produce this kind of output ?
I managed to find the tool i was referring to in my initial post. I wanted to make a reference, if anyone else needs it in the future:
it's the monitor_tc.pl script
