In Airflow a Directed Acyclic Graph ( DAG) is a model of the tasks you wish to run defined in Python. The model is organized in such a way that clearly represents the dependencies among the tasks. For example, task B and C should both run only after task A has finished. A DAG constructs a model of the workflow and the tasks that should run.Start by grabbing the task_ids and state of the task you're interested in with a db call. SELECT task_id, state FROM task_instance WHERE dag_id = '<dag_id_attrib>' AND execution_date = '<execution_date_attrib>' AND task_id = '<task_to_check>' That should give you the state (and name, for reference) of the task you're trying to monitor.In the Task name field, enter a name for the task, for example, greeting-task.
