Alert fatigue occurs when on-call engineers or operations teams are overwhelmed by the volume, frequency, or noisiness of alerts, causing them to become desensitized and slower to respond — or to ignore alerts entirely. It is one of the most common and dangerous problems in incident management.
The primary causes of alert fatigue include misconfigured thresholds that trigger too many false positives, duplicate alerts from multiple monitoring systems for the same issue, non-actionable alerts that don't require human intervention, and lack of alert prioritization (treating everything as critical).
To combat alert fatigue, teams should regularly review and tune alert thresholds, consolidate alerts to avoid duplicates, ensure every alert is actionable (if it doesn't require action, it shouldn't be an alert), implement severity levels to prioritize response, and use suppression rules during known maintenance windows. Hyperping's alert configuration and escalation policies help teams maintain a high signal-to-noise ratio.
