Can anyone recommend anything? I tend to cut my own BPF-based tools as needed to measure particular types of traffic, but that's not a very scalable approach. There are commercial products, such as NAI's Sniffer tool (I think it can read playback from pcap output), which claim to be able to help with that sort of analysis, but I've never really used them. For a "first cut" visualization of currently active network connections, tools such as ntop, trafshow, tcpstat, etc, can actually provide surprising amounts of insight.
