| workqueue_adds_total | Counter | Total number of adds handled by workqueue. |
| workqueue_queue_duration_seconds | Histogram | How long in seconds an item stays in workqueue before being requested. |
| workqueue_work_duration_seconds | Histogram | How long in seconds processing an item from workqueue takes. |
| workqueue_unfinished_work_seconds | Gauge | How many seconds of work has been done that is in progress and hasn’t been observed by work_duration. Large values indicate stuck threads. One can deduce the number of stuck threads by observing the rate at which this increases. |
