It all depends on your requirements:
- what sort of questions would you like your solution to be able to answer? (can you give us a few?)
- what monitoring infrastructure do you already have? (SNMP, for example, could be rather useful here)
- how much level of ad-hoc reporting do you require?
- you mentioned "incoming and outgoing network speeds", which doesn't necessarily refer to any web-specific analysis; is this what you meant?
Plenty of tools out there: ntop may be a good starting point.

Netflow and SNMP would be my first points of call if I wanted something more.... infrastructural.
For ad-hoc use of TCP sessions, with a top-like experience, I would just break out tcptrack (there are RPMs available, but doesn't appear to be a Centos package)
