@cypherpepe Thank you for the contribution. Could you squash the commits into one?

Hi! @ripatel-fd , thank you for the feedback!
I made the changes directly through the GitHub web interface without cloning the repository to my local machine. If squashing the commits is critical, please let me know — I will address this and perform the necessary steps locally.

Hi, I noticed that you changed book/api/metrics-generated.md. That file is autogenerated from src/disco/metrics.xml, so the changes should be made there.

@ptaffet-jump done

Can you rebase, fix the conflict, run python gen_metrics.py, then squash the commits? Otherwise it looks great!
