### Description On a dag's page in the web UI, show an indicator when the scheduling of tasks is being affected by limits on parallelism, concurrency, or a pool limit. The indicator should be relatively unobtrusive, as being affected by these things is not an error. I think it should also link to the appropriate section of the documentation describing the configuration element. ### Use case/motivation A frequent question I hear is "why isn't my task running?" The first check is parallelism, concurrency, and pools. This is tedious and unintuitive for many people, especially because there is a whole matrix of these controls. Having a UI indication come up, clearly indicate which configuration element is impacting the dag scheduling and having a link to the description in the documentation would be very helpful in directing less experienced folks to be able to answer this question on their own. ### Related issues Might be better fit with AIP-38 ### Are you willing to submit a PR? - [ ] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
