I want to know the status of dag whether it is running or failure or success. I am triggering dag through CL argument airflow trigger and after the execution of job, I want to know the status of the run. I couldn't find any way.
I tried airflow dag_state but it is giving none. What should I do if there are more than one runs in a day to get status of latest run through command line argument or through python code.
You can use list_dag_runs command with the CLI to list the dag runs for a given dag ID. The information returned includes the state of each run.
You can also retrieve the information via python code a few different ways. One such way that I've used in the past is the 'find' method in airflow.models.dagrun.DagRun
An example with python3 on how to get the state of dag_runs via DagRun.find():
dag_id = 'fake_dag_id'
dag_runs = DagRun.find(dag_id=dag_id)
for dag_run in dag_runs:
print(dag_run.state)
