+
+## Alert Details
+
+**Status:** **FIRING** | *api-gateway* service is experiencing high CPU usage. ~~resolved~~ previously.
+
+Alert triggered because ` + "`cpu_usage_percent`" + ` exceeded threshold ` + "`90`" + `.
+
+[View Alert in SigNoz](https://signoz.example.com/alerts/123) | [View Logs](https://signoz.example.com/logs?service=api-gateway) | [View Traces](https://signoz.example.com/traces?service=api-gateway)

+## Alert Labels
+
+| Label    | Value       |
+| -------- | ----------- |
+| service  | api-gateway |
+| instance | pod-5a8b3c  |
+| severity | critical    |
+| region   | us-east-1   |
+
+## Remediation Steps
+
+1. Check current CPU usage on the pod
+2. Review recent deployments for regressions
+3. Scale horizontally if load-related
+    1. Increase replica count
+    2. Verify HPA configuration
+
+## Affected Services

+## Incident Checklist
+
+- [x] Alert acknowledged
+- [x] On-call notified
+- [ ] Root cause identified
+- [ ] Fix deployed
+
+## Alert Rule Description
+
+> This alert fires when CPU usage exceeds 90% for more than 5 minutes on any pod in the api-gateway service.
