Description
Motivation¶
The job queue can increase because a worker stops taking on new jobs due to high load. This results in job age alerts and users wondering why jobs are not being run for multiple days.
See #179816#note-9 for instance.
Neither job details nor workers reveal anything about how the load would affect a job being picked up or queued longer.
Suggestions¶
- Show a note in the worker details, such as **The average load (28.32 23.48 22.95) is exceeding the configured threshold of 16. The worker will temporarily not accept new jobs until the load is lower again.
- Show a note in the job details, like All available workers are currently under high load
- The worker should actually show as Unavailable with a note in the ? button.
- It is unclear if that was true in the original cases.
- Looking at the workers table it was found that between opening the page and looking at workers the status became Idle. Maybe the status changes very quickly.

Does this have to be high prio?
I considered it High because it's relevant to understanding why jobs were queuing up. Tho it is up for debate if someone people find it easy enough to identify those jobs.
