I am trying to collect as much information as possible from a running Cardano node. Is there a way we can log the messages/packets exchanged between nodes in the Cardano P2P network?

Thank you.

  • Can you give us more information? Which platform are you running on? How did you install cardano-node? As a service(systemd) or in another way? Do you need all cardano-node logs or just part of it?

  • Hi, thank you for your response. I set up the cardano-node using the NIX package manager. I wanted to set it up as a service but could not find the documentation on how to do so. I would like to collect as much data as possible. Commented May 5, 2022 at 20:50
  • Hi, maybe this link could help you, what you need to do is to create a script to start the node and then create a service and enable it, let me know if you need help on setting things up coincashew.com/coins/overview-ada/… After that, you can check logs using "journalctl" command

  • Thank You @Nic_T2H, I will check out the steps. It seems to be a promising way to go about it. Doing this with NIX can get messy. The service will surely be the cleaner solution. Commented May 10, 2022 at 21:53
  • Good, let me know if you need help :-)

Do you really want packet level information?

If so, search the internet for network tools like 'wireshark' or 'tcpdump' and log IP/port traffic that is of interest.

If you want application level messages you can set your node logging to debug instead of the default info to get a heap more information from your node. This change will require a restart of your node.

  • Hi, thank you for your response. I changed the log file to debug and enabled logging for all the application level P2P mini-protocols. With regards to the packet level information, I wanted to collect the block information that is exchanged from specific peers along with their addresses. Wireshark/TCP dump traffic does not collect readable data. I assume the connections are encrypted. Commented May 5, 2022 at 20:48
  • I think TCP is used directly and that the connections aren't encrypted. Deserializing the raw packets will of course be a major hassle Commented Aug 24, 2022 at 20:16
