Alert Fatigue

Desensitization of responders caused by too many, too noisy, or non-actionable alerts, leading to missed real incidents.

Definition

Alert fatigue is reduced by alerting on symptoms tied to SLOs, routing by severity, deduplicating and grouping alerts, and deleting alerts that never require action.

Example

An on-call engineer ignores a real outage page after receiving 200 flapping CPU alerts that night.

Exam tip

The fix is fewer, actionable, SLO-based alerts, not adding more responders.
