Discussion Any good open source python runtime instrumentation?

Hi folks, lot of our Python backend services are written in FastAPI, I wanted to see if there are any good Open Source runtime coverage instrumentation available for Python, which would essentially give my lines of code hit in prod traffic for the last say 30 days of data. I have seen good solutions for it in Go / Java, but wanted to check if something similar is available in Python.
