--------------------------------------
Summary: Capture stats for dagrun schedule delay for
adhoc/nonschduled task
Key: AIRFLOW-4596
URL: https://issues.apache.org/jira/browse/AIRFLOW-4596
Project: Apache Airflow
Issue Type: New Feature
Components: models
Affects Versions: 1.10.3
Reporter: Himanshu Garg
Assignee: Himanshu Garg
With respect to the metric we are capturing in airflow version v1-10 -
https://github.com/apache/airflow/blob/v1-10-stable/docs/metrics.rst. The Timer
merics `dagrun.schedule_delay.<dag_id>` `Seconds of delay between the scheduled
DagRun start date and the actual DagRun start date`
we are capturig the delay of only schduled Dags.
But we can also include delay in the adhoc/non-scheduled Dags by capturing the
difference between `start_date` in `dag_run` table and `start_date` in
`task_instance` table keeping the `dag_id` and `excecution` date as the
cardinality for performing join.
