Hey all, was wondering if anyone knows about any well known tools/libraries to process and analyze pants' workunit logs. I'm trying to print some stats around cache hits/misses and execution times by parsing them, and thought I'd ask before delving in too deep. Thank you very much in advance. 🙂

I think @fresh-mechanic-68429 and @curved-manchester-66006 had some PoCs for converting workunits to various tracing backends (honeycomb, otel respectively), but I don't think either of them were public :(

I finally converted mine to otel (from honeycomb). Has been useful very helpful for us, I still hope to opensource it at some point. But if you're interesting in doing it on your own, checkout the

WorkunitLoggerCallback

I'd definitely be interested in using it if you open sourced it in whatever state it's in

Thank you both 🙏 😄
