Alerts & Notifications

    How do I route and suppress alerts from a rule?

    Every rule has a routing block: pick channels, set quiet hours, dedupe windows, and escalation paths so noisy rules never wake the wrong person.

    Quick answer#

    Inside each rule, open Routing to pick channels (email, Slack, webhook, SMS), set Quiet hours, choose a Dedupe window (default 15 min), and add an Escalation step if the alert is not acknowledged.

    Routing options#

  1. Channels — one or many; overrides global defaults for this rule
  2. Quiet hours — timezone-aware; alerts queue and fire when quiet ends
  3. Dedupe window — suppresses identical fires within N minutes
  4. Escalation — re-fire to a secondary channel after X min unacked
  5. Auto-resolve notice — send a "recovered" ping when the condition clears
  6. Where to find it in Lemwatch#

    Settings → Alerts → Rules → (pick rule) → Routing.

    How to tame a noisy rule#

  7. Widen the for duration on the condition (e.g. 2 min → 10 min).
  8. Raise the dedupe window to 30–60 min.
  9. Move low-severity channels behind an escalation step.
  10. Enable Quiet hours for overnight windows.
  11. If still noisy, add an AND condition to require a corroborating signal.
  12. FAQ#

    Do suppressions apply to auto-resolve messages?#

    Quiet hours delay them; dedupe does not. Recovery pings always send once.

    Can I route different severities to different channels?#

    Yes — clone the rule per severity and route each separately.
