What happened?

I’ve recently migrated from StatsD to OpenTelemetry and am now sending metrics to Splunk Observability.

However, I’ve noticed that some metrics are now missing after this change, such as operator_successes, operator_failures, and some custom metrics that I used to see when using StatsD with the Python stats package in my DAGs.

The common factor among the missing metrics is that their descriptions in the Airflow documentation mention “Metric with xyz tagging.” I’m not sure if this is relevant.

What you think should happen instead?

All metrics, including operator_successes, operator_failures, and custom metrics, should be available as they were with StatsD.

How to reproduce

• Migrate from StatsD to OpenTelemetry.
• Send metrics to Splunk Observability.
• Observe the missing metrics such as operator_successes, operator_failures, and custom metrics.
