+**MySQL**
+```
+Host: 127.0.0.1
+Port: 3306
+Database: test
+Username: root
+Password: 123456
+```
+

+Host: 127.0.0.1 or 192.168.1.6
+Port: 6379
+Password: (none)
+```
+
+### Monitoring System
+
+The complete monitoring stack is deployed via Docker Compose in the `monitoring/` directory.
+
+**Quick Start:**
+```bash
+cd bigscreen/monitoring
+docker-compose up -d
+```
+
+**Key Endpoints:**
+- Grafana dashboards: http://localhost:3001 (admin/admin123)
+- Prometheus queries: http://localhost:9091/graph
+- Prometheus targets: http://localhost:9091/targets
+- Alertmanager: http://localhost:9094/#/alerts
+- Application metrics: http://localhost:5225/metrics
+
+**Documentation:**
+- Full monitoring setup guide: `bigscreen/monitoring/README.md`
+- Includes Prometheus, Loki, Grafana, Alertmanager
+- Pre-configured dashboards for health data, API performance, alerts
+- 15+ alert rules for application and system monitoring
+
+### Port Mappings (Avoiding Conflicts)
+
+The monitoring system uses non-standard ports to avoid conflicts:
+- Prometheus: 9091 (not 9090 - conflicts with OrbStack)
+- Alertmanager: 9094 (not 9093 - conflicts with ClashX)
+- Node Exporter: 9101 (not 9100 - conflicts with OrbStack)
+- Grafana: 3001 (standard)
+- Loki: 3100 (standard)
+
+### Security Notes
+
+⚠️ **IMPORTANT**: These are development/testing credentials
+- **Production**: Change all default passwords before deployment
+- **Grafana**: Change admin password on first login
+- **MySQL**: Create dedicated app user with limited privileges
+- **Redis**: Enable password authentication for production
+- **Network**: Keep monitoring services on internal network only
+
