 A _process_ is also considered "saturated" when its top-level `worker_concurrency` flow metric approaches the _cumulative_ `pipeline.workers` across _all_ pipelines, and similarly can be addressed by tuning the <<pipeline-stats,individual pipelines>> that are saturated.

-This is a unitless metric that indicates the percentage of available worker time being used by all plugins in a given pipeline (`duration` / (`uptime` * `pipeline.workers`).

-A _pipeline_ is considered "saturated" when its `worker_utilization` flow metric approaches 100, because it indicates that all of its workers are being kept busy.
-This is typically an indication of either downstream back-pressure or insufficient resources allocated to the pipeline.
-Tuning a saturated pipeline to have more workers can often work to increase that pipeline's throughput and decrease back-pressure to its queue, unless the pipeline is experiencing back-pressure from its outputs.

-Tuning a starved pipeline to have fewer workers can help it to consume less memory and CPU, freeing up resources for other pipelines.

 | queue_backpressure |
 This is a unitless metric representing the cumulative time spent by all inputs blocked pushing events into their pipeline's queue, relative to wall-clock time (`queue_push_duration_in_millis` / millisecond).
 It is typically most useful when looking at the stats for an <<pipeline-stats,individual pipeline>>.

 NOTE: The size of a PQ on disk includes both unacknowledged events and previously-acknowledged events from pages that contain one or more unprocessed events.
       This means it grows gradually as individual events are added, but shrinks in large chunks each time a whole page of processed events is reclaimed (read more: <<garbage-collection, PQ disk garbage collection>>).
