You're almost there! Left you some comments to trim a bit what's not used in RMT.

lgtm 👍

I'm not really sure what is the scope. The metric export now most information, I hope this is fine.

How I reviewed this merge request:

• Checked the code changes make sense to me
• Ran the branch and checked /metrics is populated (also in error case)

As always, if you think I missed something I should test, please let me know!🚀

cheers,
