build/buy a ethertap, (or use a hub) in the ip stream you need to
monitor.
add in a box running ipfm (debian package available)
this gives you traffic/ip in a list updated as often as you want/need
i picked 5 minutes to match my other graphs
then run rrdtool on that list to build the graphs per/ip
and make a nice web page to present the lot.
ethertap from netoptics:
