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.
