Best way to nail down ports and protocols used between subnets

hello, what are some ways to accomplish this? looking to verify the protocols and ports that are used between a dmz and internal network off of a cisco asa 5525. i've done a couple packet captures on the asa but the 33mb buffer fills up in about 30min so its not a great representation of all the traffic.. should I be looking into something like port mirroring?

I did just find out that asa captures can be saved as pcaps and then viewed in wireshark which is nice.
