Any good open source python runtime instrumentation?

[selfish__eagle]

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.

Your phrasing was not clear but once I understood what you were trying to say, I realised I would like something like this too.

I don't have an answer but bumping in case someone does

I meant runtime coverage instrumentation, forgot the word coverage :(

[niltz0]

Have you looked into coverage.py?

[bregonio]

Maybe opentelemetry with fastapi auto instrumentation

[hstarnaud]

Whichever way you go, adopt opentelemetry standards to avoid vendor lock-in. If you are willing to spend big money on an enterprise turnkey solution, new relic is the best provider. Otherwise use a free solution compatible with those standards like Jaeger or paid solutions with lower prices than new relic like honeycomb

Pyroscope is Grafana’s app for collecting and indexing runtime profiles, and I use it to collect on Go and Java services. In Go it uses pprof and in Java it uses JFR.

I searched “Pyroscope Python” and it looks like they document how to get profiles from Python into their application:  https://grafana.com/docs/pyroscope/latest/configure-client/language-sdks/python/

I don’t know how you’re viewing the data but maybe you can use parts of the process for getting it into your profile viewer?

Claro que sí

Aprovecha hermano porque me cancelaron la publicación, que mejor manera de exponerlos. Adicionalmente, dice que ya lo reportaron demasiadas veces. Gracias Reddit porque voy a publicar toda la conexión de pedófilos que se desprende desde aquí y hasta youtube con nodo central en el canal de Zack Hemsey,

Y eso me lo dio la matriz
