Alert Fatigue
ELI5 — The Vibe Check
Alert fatigue is when you get so many monitoring alerts that you stop reading them. Your phone buzzes 50 times a day with warnings that are 'normal.' So when a REAL emergency alert fires, you ignore it too — because it looks exactly like the other 49 false alarms. It's the developer version of 'The Boy Who Cried Wolf.' The solution isn't fewer monitors — it's better thresholds.
Real Talk
Alert fatigue occurs when monitoring systems generate excessive alerts — many of which are false positives, duplicates, or low-severity — causing engineers to become desensitized and miss critical incidents. It's a leading contributor to increased incident response times and is particularly dangerous during on-call rotations. Combating it requires alert tuning, deduplication, severity tiering, and regular alert hygiene reviews.
When You'll Hear This
"We get 200 alerts a day — pure alert fatigue. Nobody reads them." / "After the outage, we realized alert fatigue caused a 30-minute delay in response."
