How do I check if there are DAGs running in Airflow (before restarting Airflow)?

问题

I need to restart Airflow. I want to make sure I do it when it's idle, so I that I don't interrupt a job by restarting the worker component of Airflow.

How do I see what DAGs are running?

I don't see anything in the UI that would list currently running DAGs.

I don't see any command in the airflow CLI to list currently running DAGs.

I found airflow shell that lets me connect to the DB, but I don't know enough about Airflow internals to know where to look to see what's running.

You can also query the database to get all running tasks at once:

select * from task_instance where state='running'

I found it... it's in the UI, on the DAGs page, it's the second circle under "Recent Tasks":
