Well anyone can do it easily with go bench and benchstat these days, exported to @prometheus.io or sheet graphing.

Maybe you meant benchmark.vitess.io ?

Common painful thing.

But I think we found epic solution, available from next @prometheus.io version, who knows!

I've just updated all of my Prometheus monitoring trainings at training.promlabs.com to Prometheus v3 and also updated most other component versions (Alertmanager, exporters, Prometheus Operator, SDKs, ...) to keep things fresh.

Check out the trainings if you want to learn @prometheus.io :)

We see more and more questions/responses on GitHub issues on OSS projects clearly generated with the help of GenAI - very generic, asking kind of unrelated questions.

Quite hard to judge what part contributor exactly does not understand and how to help.

Do you experience similar? Any tips? (:

Thanks! Yea this is really generous from Go side, hope users realise that (:
