Hi everyone, Over the last couple of weeks I've been learning about Cockpit internals, and hacked together a little proof-of-concept page listing and playing back user sessions recorded with tlog [1]. Here is a little demo of it I recorded: https://youtu.be/BPiqFKvW0q4 And here's the code: https://github.com/Scribery/cockpit/tree/hacking/pkg/session_recording The POC has absolutely minimal functionality and is not pretty, but it proves we can record sessions to systemd journal, and list them and play them back. Tlog-rec-session (a part of tlog) logs a recording as a series of messages, with several extra journal fields attached to allow for filtering all or specific recorded sessions from the rest of the journal log. Cockpit goes through journal extracting all tlog messages to collate a session list. When asked to playback a session, it starts tlog-play (another part of tlog) on the host, specifying how to extract session messages, connects it to a terminal emulator in the browser, and lets it play. Next, me and Kyrill are going to work on verifying we can implement the rest of the required core functionality [2] with this approach, learn more about Cockpit, and prepare a design as required by Cockpit team [3]. We will also see if we can make this into an out-of-tree package for Cockpit. We would appreciate any comments you might have, be it on the architecture, the code, or the way you think it should look! Thank you.
