Description

Is your feature request related to a problem?

I use python auto instrumentation for my FastAPI application.

I want to do zero code insert for opentelemetry like this docs

The log and trace were perfectly send to opentelemetry collector by following instrumentation in kubernetes:

apiVersion: opentelemetry.io/v1alpha1
kind: Instrumentation
metadata:
  name: opentelemetry-instrumentation
  namespace: opentelemetry-operator-system
spec:
  defaults: {}
  exporter:
    endpoint: http://opentelemetry-collector.open-telemetry.svc.cluster.local:4318
  propagators:
    - tracecontext
    - baggage
  python:
    env:
      - name: OTEL_PYTHON_LOGGING_AUTO_INSTRUMENTATION_ENABLED
        value: 'true'      
    image: >-
      ghcr.io/open-telemetry/opentelemetry-operator/autoinstrumentation-python:0.50b0
    resourceRequirements:
      limits:
        cpu: 500m
        memory: 64Mi
      requests:
        cpu: 50m
        memory: 64Mi
    volumeClaimTemplate:
      metadata: {}
      spec:
        resources: {}
  resource: {}
  sampler:
    argument: '1'
    type: parentbased_traceidratio

If I specified OTEL_PYTHON_LOGGING_AUTO_INSTRUMENTATION_ENABLED to true, the log which use logging will be send to opentelemetry collector, but disappear in console.

How can I send the log to opentelemetry and print in console by logging using python auto instrumentation?

If possible, I want to maintain the concept of zero code. I don't want to change the application code.

thanks

Describe the solution you'd like

I can use variable or something that I can send logging log to console and opentelemetry collector

Research direction

Start with the Python zero-code instrumentation documentation linked in the issue and the Kubernetes Instrumentation manifest, focusing on OTEL_PYTHON_LOGGING_AUTO_INSTRUMENTATION_ENABLED. Determine whether configuration can preserve console output while exporting logs to the collector without application changes; done means logs appear in both destinations.
