I have a need to set up a capture for 24 hours and what I am interested in keeping is just the information in the Statistics | Conversations | TCP or UDP tabs, just interested in what IPs are talking to each other and what ports were used. There will be a lot of data if I try to keep all of the packets, is there a way to just have the capture running, retain the conversation information, and not save the data?

Wireshark and tshark keep state information in memory and are not the best tools for monitoring long-term. Especially if you are only interested in conversation statistics.

Have a look at ntop, which exactly does what you want :-)

Tshark[a command line equivalent of wireshark] might be one of the solutions. With that You can give the duration of the capture.You can set the capture filter for tcp || udp.You can retrieve the fields you want at the end by using -Tfileds option.
