I love the idea of having metrics for things like "how long are people spending waiting on builds".

You mention that you're trying to get data from existing tools rather than requiring self-reporting. What are you using to track time spent on local builds?

I'm currently building a service to speed up both local and CI builds. I'd love to talk with you more; my email is in my profile.

For time spent on local builds, we expose a tracing-like API where you can tag the build id, start and end events, as well as connect it back to the right team. This custom event gets joined with everything else. I'll reach out to you on your email!

This is super cool. We know way more about Docker than we should now, but it seems like you could instrument local Docker for some teams.
