Deduplicate Noisy Alerts Into a Single Incident

Cut alert fatigue — group related alerts from the same root cause into one incident instead of paging engineers repeatedly.

  1. 1

    Ingest Alerts

    Add a Webhook node receiving each raw alert with its service and signature.

  2. 2

    Group Related Alerts

    Add a Code node with Redis matching alerts to an existing open incident by service and time window.

  3. 3

    Create or Update the Incident

    Add a PagerDuty node opening a new incident or appending to the matching one.

  4. 4

    Resolve When Clear

    Add a step closing the incident once alerts stop for a cool-down period.

  5. 5

    Activate and Test

    Activate the workflow and fire several related alerts. Confirm they collapse into one incident.

Frequently asked questions

How wide should the grouping window be?

Wide enough to catch the same outage's alerts, narrow enough not to merge unrelated issues — tune per service.

Won't I miss a second real issue?

Group by service and signature so a genuinely different failure still opens its own incident.
