You could use Adventnet's Opmanager
(http://manageengine.adventnet.com/products/opmanager/index.html). Using SNMP (or SNMP/WMI for
Windows) you can get a graph based on the intefaces traffic. I have used it for about a year now and
am extremely pleased with it
(goodbye Nagios). 

There are actually a lot of other tools out there, the key being that the endpoints have either snmp
or WMI. Too bad that m0n0wall
doesn't work with their Firewall Analyzer. I use that with my PIX and get a lot more detailed output
on each indiviual device.
