I could try running tcpdump or wireshark, but that's going to generate a lot of data and I'm not sure how to go about filtering it.
Not necesarily, you just need to look at the packets for 0 and 30, I think this is definitely THE way to go about it. http://www.wireshark.org/docs/wsug_html_chunked/AppToolstcpdump.html
In addition jnettop could be helpful as well.
