Hi! I have Pants running in my CI pipeline for a long time now and in a repo which is quite big. I'm at a point now where I want to be able to instrument Pants with telemetry (traces) to find inefficiencies like dependency bottlenecks / hot-spots and slow steps so I could optimize the pipeline. Is there a way to do it today natively, with a plug-in, or by parsing Pants' logs/dump? If not, does it seam feasible for me to work on such a plugin / upstream patch? (any pointers?) Thanks! 🙂

Toolchain (RIP) had this feature, and that repo is now open-sourced: https://github.com/toolchainlabs/toolchain-oss
I don’t think you could use that out of the box without running a whole lot of server stuff, but you could reuse parts of that code, or at least derive inspiration from it, with an eye to upstreaming it into the pants repo
@fast-nail-55400 and @witty-crayon-22786 know more about the details, I think
What were you thinking of for visualizing the traces?
I believe we had a semi-manual way to dump traces out of Pants and load them into the zipkin UI, for example, but my memory is hazy

I'm thinking about something like Grafana Traces or Honeycomb using OpenTelemetry.
And thanks, I'll take a look 🙂 (sad though that Toolchain didn't 🚀)

Coo, so FWIW the necessary data can be exposed via plugin (and the Toolchain plugin captured it), so hopefully that will be a good starting point
Feel free to copy/change/modify that code with an eye to upstreaming it

I recently wrote an OpenTelemtry plugin for Pants.

Thanks, @happy-kitchen-89482! @fast-nail-55400, are you teasing me he? XD Can you please share more details? 🙃 (or in a PM if you are waiting with a great reveal?)
