OpenTelemetry metrics are not getting sent

[nazarii-koblai]

Official Helm Chart version

1.15.0 (latest released)

Apache Airflow version

2.9.3

Kubernetes Version

1.28.9

Helm Chart configuration

config:
  metrics:
    otel_on: 'True'
    otel_host: opentelemetrycollector-service.observability
    otel_port: '4318'
    otel_prefix: 'airflow'
    otel_debugging_on: 'True'

Docker Image customizations

Yes, I did extend official airflow image with some additional dependencies and minor UI changes.

What happened

After applying values.yaml configuration I don't see any either logs about metrics or calls to the OTEL collector.

What you think should happen instead

Logs about metrics should be shown and those metrics should be sent to OTEL collector.

How to reproduce

Try to change airflow.cfg or use env variables to setup OpenTelemetry metrics.

Anything else
