Hardcoded Opentelemetry SERVICE_NAME

[nicolasge]

Apache Airflow version

2.10.1

If "Other Airflow 2 version" selected, which one?

No response

What happened?

When enabled the OTEL in Airflow, the OTEL_SERVICE_NAME is hardcoded to "Airflow". Based on https://opentelemetry.io/docs/languages/sdk-configuration/general/ users should be able to overwrite this to any value via environment variable OTEL_SERVICE_NAME.

Bug line: resource = Resource(attributes={SERVICE_NAME: "Airflow"})

What you think should happen instead?

If user specified OTEL_SERVICE_NAME via environment, airflow use should this value instead of hardcoded value which is "Airflow"

How to reproduce

During the installation, inject an extra environment OTEL_SERVICE_NAME and set the value to a value not equal to Airflow

Apparently otel configuration already have service_name configuration, I duplicate it to the metrics section and apply it on the service name.

Let me know what you think on the PR
