logfire.instrument_*() methods

[alexmojaki]

e.g. logfire.instrument_sqlalchemy() instead of from opentelemetry.instrumentation.sqlalchemy import SQLAlchemyInstrumentor; SQLAlchemyInstrumentor().instrument(). Same for all integrations documented in https://docs.pydantic.dev/logfire/integrations/#opentelemetry-integrations.

Remaining methods to add:

• logfire.instrument_flask()
• logfire.instrument_starlette()
• logfire.instrument_aiohttp()
• logfire.instrument_sqlalchemy()
• logfire.instrument_pymongo()
• logfire.instrument_redis()
• logfire.instrument_celery()
• logfire.instrument_asgi_middleware()
• logfire.instrument_wsgi_middleware()
• logfire.instrument_logging_handler()
• logfire.instrument_loguru_handler()
• logfire.instrument_structlog_processor()

I'm not sure about the names of the last 5. It is important that they're methods of logfire objects rather than classes imported from logfire. It would be nice for everything to start with instrument_ but instrument_logging_handler sounds like it's instrumenting a logging handler, rather than returning a handler that 'instruments logging'.

@Kludex I'm going to start working on the first 6, please do the other half.

[alexmojaki]

@Kludex I think we should have logfire.instrument_loguru() which calls logger.add(**logfire.loguru_handler()). That makes the naming less weird and should be easier for users, avoiding problems like #228. logfire.loguru_handler() can be kept for compatibility but not recommended.

[Kludex]

Is this done? @alexmojaki

[alexmojaki]

No because I did half and I asked you to do the other half.

About the ASGI and WSGI, I'm not sure if it makes sense to create those methods.

Maybe wrapping them, and providing a logfire.InstrumentASGIMiddleware and logfire.InstrumentWSGIMiddleware makes more sense. wdyt @alexmojaki ?

[alexmojaki]

They need to be methods so that you can use them with different logfire objects that have different configs.

We could maybe just call them instrument_asgi/wsgi. Then the docs would suggest app = instrument_asgi(app) which doesn't look weird. It's only 'middleware' in the context of higher level frameworks which choose that terminology. For example the starlette OTEL instrumentation has app.add_middleware(OpenTelemetryMiddleware, ...). But we don't really have to call it that.
