How to publish DAG status metrics to Logfire

Install airflow-priority[logfire] and obtain a write token for the destination Logfire project:

[priority.logfire]
token = YOUR_WRITE_TOKEN
metric = airflow.priority
threshold = 2

Restart Airflow components and trigger a failing P1/P2 test DAG. Find the airflow.priority.p1.failed or airflow.priority.p2.failed gauge in Logfire. Configure an external alert on a positive failure sample with a window suited to the workflow’s cadence.

Keep metric names aligned with the configured metric prefix. The state suffix is success, not succeeded. See the metric reference for defaults and the limitations of process-local status adjustments.
