Operational Remediation Reports

Saturation Relief Remediation Report

Compare queue depth against soft and hard limits and pick a saturation relief action.

saturation selector The queue depth is the only selector that changes between report variants.
relief action Crossing the soft limit sheds load and crossing the hard limit pauses intake.
