I am using Centos 4.0 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. -- Les Mikesell lesmikesell at gmail.com
