I'm looking for tools to monitor network traffic. I'm not looking for a protocol analyzer (sniffer). I already have what I need for packet decodes. (TCPdump, Ethereal, etc.) What I want is something that will give me a protocol breakdown. For example, I already have tools to tell me that traffic levels on a given network are at 20%. I want to get a graph of the breakdown of that traffic. How much of it is http? How much ftp? How much something else?

Any suggestions?
