    AI alert noise reduction

    Suppresses flapping alerts, deduplicates simultaneous incidents, and silences known-noise patterns — cuts alert volume by 50–80% for most teams.

    Quick answer#

    Three layers: (1) confirmation gates before an alert fires, (2) dedupe of simultaneous incidents on the same root domain / provider, (3) learned suppression of recurring known-noise patterns.

    How each layer works#

  1. Confirmation gates: an outage must fail N consecutive checks across ≥2 regions before we page you
  2. Dedupe: 30 incidents on cloudfront.net → 1 grouped incident with 30 affected sites
  3. Learned noise: if you ack the same pattern 3+ times, we suggest auto-suppressing it
  4. Where to find it in Lemwatch#

    Settings → Alerts → Noise reduction.

    How to tune#

  5. Start with defaults — safe for most teams.
  6. If you page an on-call human, raise the confirmation threshold.
  7. Review "Suggested suppressions" weekly and accept the safe ones.
  8. FAQ#

    Will I miss a real outage?#

    Confirmation adds ~60s median. Hysteresis prevents oscillation. Real outages are never suppressed — only flapping is.

    Can I disable noise reduction?#

    Yes, per rule — but you'll pay for it in pager fatigue.
