Inconsistent last_dag_run_state in web ui in Airflow 3

[m-fariz-a]

Previously, I am using Airflow 2.10. After upgrading to Airflow 3, I figured that the stat summary for last_dag_run_state is not correct. I am not really sure why this is happen, but upgrading to latest airflow 3 didn't solve the problem.

I checked airflow metadata and found that there were 3 dag failed today, but only one that has not been rerun successfully.

That's not the same for success state. At the current screen capture (video and image), the dag queued status came from a dag that was running with max_active_runs=1 (it has multiple queue trigger run).

Is this a bug or just me misunderstanding the purpose of last_dag_run_state in Airflow UI?

I just upgraded the Airflow image to 3.1.0, and there are some changes:

• There are only three stats at the top: Queued Dags has been removed from the top stats but still appear in history section, which I think makes sense.
• Failed Dags now shows the correct number of failed DAGs.
• Running Dags only counts DAGs that are running on schedule, while the history section shows DAGs scheduled by assets and by timetable.
