Group Incidents to Reduce Noise | All Quiet Payload Mapping Guide
Quick answer
Grouping in All Quiet payload mapping merges alerts that share the same attribute value, such as a cluster ID, into one incident so on-call engineers get a single notification instead of a storm of duplicates. The Grouping Window limits how long grouping stays active so new issues are not hidden inside older grouped incidents.

Alert fatigue hits hardest when one root cause triggers dozens of notifications. Grouping inside payload mapping keeps your on-call workflow focused without hiding new production issues — and implementing robust incident management software ensures that engineering teams see one actionable incident instead of a flood of duplicates.
When grouping helps
Separate incidents such as "High API Latency" and "Database Connection Timeout" may share the same cluster identifier even though they arrive as distinct alerts. Grouping merges them so engineers receive one notification while still seeing every payload in the incident details.
Enable grouping in 3 steps
- Map a shared field such as
cluster_idto a Cluster attribute in payload mapping. - Enable the Grouped column for that attribute and save the integration.
- Re-trigger related alerts and confirm they appear under one grouped incident.
Grouping behavior reference
| Setting | Function | Example outcome |
|---|---|---|
| Grouped attribute | Matches open incidents on the same value | Production-East alerts merge |
| Severity inheritance | Uses highest sub-incident severity | Critical child keeps parent Critical |
| Grouping Window | Limits how long grouping stays active | 3,600 seconds = 1 hour window |
| After window expires | Creates a fresh incident for new issues | New cluster alert after 2 hours stays visible |
Use the Grouping Window deliberately
Without a time limit, a new issue hours later could attach to an old grouped incident and never trigger a fresh notification. Set the Grouping Window in seconds so only alerts within that interval merge, for example 3,600 for one hour.
Key takeaways
- Grouping reduces duplicate notifications while preserving every payload inside one incident.
- Severity follows the highest sub-incident so critical signals are never downgraded.
- Grouping Window prevents unrelated later alerts from disappearing into stale incidents.

Frequently asked questions
What does the Grouped column do in payload mapping?
When Grouped is enabled on an attribute, new payloads with the same value attach to an existing open incident instead of creating a new one.
How is severity calculated for grouped incidents?
The grouped incident uses the highest severity among its sub-incidents so critical signals are never downgraded.
Why do I need a Grouping Window?
The Grouping Window prevents unrelated alerts hours later from being merged into an old incident, which would hide new production issues.
