There are several tools that will collect interface traffic data via 
SNMP and record it so you can graph, show high/low/average values over a 
time span, etc.  Cacti (in the epel repo) is probably the easiest to set 
up, OpenNMS (http://www.opennms.org) probably the most complete.  These 
could also get their data from a port on a managed switch or router if 
that makes it easier to show the connections you need to split out.
