+## 🔗 Integration
+
+This observability stack is part of a larger ecosystem:
+
+- Ced’s HomeLab → Infrastructure layer
+- Ced’s Observability Stack → Metrics + monitoring layer
+- Ced’s NOC → Visualization and operations layer
+
+Data flows from monitored systems into Prometheus, is visualized in Grafana, and feeds Ced’s NOC dashboard for real-time system visibility.
+
+---
+
+## 🧪 Verification
+
+To verify the system is working correctly:
+
+### Prometheus Targets
+
+- Navigate to: http://localhost:9090/targets
+- Confirm all targets show UP
+
+---
+
+### Node Exporter
+
+bash curl http://<node-ip>:9100/metrics 
+
+---
+
+### Service Health Check
+
+bash python3 scripts/service-health-check.py 
+
+---
+
+### Grafana
+
+- Confirm dashboards display real-time metrics
+- Verify data source connection to Prometheus
+- Check for active alerts
+
+---
+
+### Alert Testing
+
+- Stop a service or node temporarily
+- Confirm alert triggers in Prometheus
+- Confirm alert appears in Grafana
