[jira] [Commented] (AIRFLOW-5647) Airflow UI should also display dag_concurrency reached

    [ https://issues.apache.org/jira/browse/AIRFLOW-5647?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17051242#comment-17051242 ]

-----------------------------------------

Hi Mentors,
By tracking the dag_concurrency count from the airflow config and update the blocker to pass another field in the payload can help us to resolve the issue.

It will be great if someone can confirm it?

> Currently, in the main view, the schedule column box is highlighted in red if the max. number of DAG runs is achieved. In this case no more DAG runs can be started until a DAG run completes.
> I think it should also display in red when the dag_concurrency (i.e. max concurrent tasks) is achieved. In this case also, no more tasks can be started until a task completes. However there is currently nothing in the UI showing that (currently running 1.10.5).
