I'd suggest logging to sqlite to provide later replays and speed estimations at keypoints. It might be nice to also add some cascading signature of the timestamps for tamper evidence (ex: merkle tree)

Usecase: storing timestamped proof of execution, automating metrics history

User story: "after feature X got implemented, deployment became twice as slow as we can see from the viddy logs".



ttyrec[1] would be an alternative format that's been around for a while.

Would be an interesting feature to see here for recording, and can then be played back/analysed by various other tools.

I didn't know that format. Actually, I'm looking for the solution to record and review that later. It might be fit.

Thank you!
