If you want something more of a web service you could install SNMP
from ports and use Cacti (also from ports). See http://www.cacti.net/
for a quick glance at what you'll get.

thanks to all for your suggestions. i looked into the tools but
unfortunately none was simple enough so that its output could be easily
parsed and used as a superkaramba sensor. finally i came across
"ifstat" (also from ports) which seems to be what i was looking for,
but nevertheless thanks for your help :)

I hope I am not stealing the thread by asking an additional question. Thanks to this thread I discovered :) systat -ifstat and other switches. Does such data like below survive reboots?
