Alert level
Also called alert limit
アラートレベルarāto reberu
An internal level, below the action level, that signals a departure from normal conditions while results are still acceptable. Exceeding it calls for closer attention, such as reviewing trends and possible causes, but not necessarily corrective action. Alert levels are usually based on historical monitoring data. Repeated alert-level results are commonly treated as an adverse trend that needs investigation, so read a site's escalation rules, not just its limits.
