Cacti: http://www.cacti.net will do total bandwidth charts
with snmp.  You can watch the switch ports or run snmp on
all the machines or both.  However it does not break down
the application usage.  If you can bridge all the traffic
onto one port on your switch, ntop (http://www.ntop.org)
will provide a breakdown by port, although if you have a
lot of traffic it may have trouble keeping up.  It is a
handy tool that makes it easy to spot virues and people
running peer-to-peer file xfer but I don't completely trust
it.
