How Fatigue Sets In

  • • Too many alerts cause important alerts to be missed
  • • Each missed incident tends to add reactive alerts
  • • The extra noise feeds the next round of ignored alerts

Prevention Strategies

  • • Threshold adjustment: do not set overly sensitive thresholds
  • • Alert grouping and inhibition: bundle related alerts, suppress child alerts
  • • Review precision and user impact; send non-urgent work to tickets
