Hi, very new to this ecosystem. I am struggling to get a basic fastapi instrumentation up with the automatic instrumentation command, even a basic console export is not working, here is the command I supplied:
opentelemetry-instrument --traces_exporter console --metrics_exporter console $APP_CMD
The $APP_CMD is just using uvicorn to run the app without hot reload as advised.

What does the $APP_CMD look like? Multiple workers are not supported (yet) by opentelemetry.

No just one teeny tiny worker
uvicorn main:app --app-dir /my_service --host 0.0.0.0 --port 3000

it should work, are no spans being written to console when you send requests to this app?

Yeah, none
Might sound silly but is there something I need to add to the app itself ? Like instrument_app by importing the sdk

That’s not really needed, can you share a simple reproducible app?

I actually run it in docker, maybe if you reckon the config is fine so far, Ill probably tear down the whole thing rebuild it to see if it persists and if it does, will I share reproducible app?
