Description
Describe your environment
Python 3.10.12
Steps to reproduce
Using the code here, but with a logging.info rather than logging.warning: https://github.com/kuza55/pants_debug_otel/blob/main/src/no_configuration.py
I would expect setting OTEL_PYTHON_LOG_LEVEL=INFO to let me see info logs
What is the expected behavior?
I would expect to use the OTEL_PYTHON_LOG_LEVEL env variable mentioned in the docs to let me see info logs.
What is the actual behavior?
Environment variable has no impact
Additional context
Calling LoggingInstrumentor().instrument(set_logging_format=True, log_level="INFO") can resolve this, but is not compatible with auto-instrumentation, even when the auto-instrumentation env variable is set to false:
$ OTEL_PYTHON_LOGGING_AUTO_INSTRUMENTATION_ENABLED=false opentelemetry-instrument python3 no_configuration.py
Attempting to instrument while already instrumented

Research direction
Start with the auto-instrumentation path exercised by opentelemetry-instrument and compare it with LoggingInstrumentor().instrument(set_logging_format=True, log_level="INFO"). Reproduce the behavior using no_configuration.py and OTEL_PYTHON_LOG_LEVEL=INFO; done means INFO logs are captured through auto-instrumentation without triggering the already-instrumented warning.
