How to decode Aeron network data captures with Wireshark


You want to debug Aeron at the network level and have the Aeron protocol network packets decoded within Wireshark.


Capture the network traffic of interest using your tool of choice (Wireshark, tcpdump etc) in the Wireshark format.

Then, within Wireshark, enable the aeron_udp protocol:

Aeron Wireshark protocol


Aeron Wireshark output


The Wireshark protocol only shows the bottom level Aeron Transport Protocol. Protocols built on top of this - such as that used by Aeron Archive and Aeron Cluster - are not decoded.
