## 🎯 Usage

### Access Monitoring Dashboard
1. Navigate to `http://localhost:5000/monitoring` or `/monitoring` in the app
2. View overall health summary for all services
3. Click on a service card or tab to see detailed metrics
4. Select an environment to filter metrics
5. Click "Collect Metrics" to gather fresh data

### Collect Metrics
```bash
# Via API
POST /api/monitoring/environments/workload-azure-eastus/collect

# Via UI
1. Select environment
2. Click "Collect Metrics" button
```

### View Service Metrics
```bash
# Besu
GET /api/monitoring/besu?environment=workload-azure-eastus

# Cacti
GET /api/monitoring/cacti?environment=workload-azure-eastus

# Firefly
GET /api/monitoring/firefly?environment=workload-azure-eastus

# Chainlink CCIP
GET /api/monitoring/chainlink-ccip?environment=workload-azure-eastus
```

## 🔌 Integration Points

### Current Implementation
- Simulated metrics (ready for Prometheus integration)
- Database storage for historical data
- Real-time WebSocket updates
- Health status calculation

### Future Integration
- **Prometheus**: Replace simulated metrics with actual Prometheus queries
- **Grafana**: Export dashboards
- **AlertManager**: Set up alerting rules
- **Custom Metrics**: Add service-specific custom metrics

## 📊 Metrics Storage

All metrics are stored in the `service_monitoring` table:
- Service name and type
- Metric name and value
- Status (healthy/degraded/unhealthy)
- Timestamp
- Environment
- Metadata (JSON)

## 🎨 UI Features

- **Health Overview Cards**: Quick status view
- **Service Tabs**: Easy navigation between services
- **Metric Cards**: Individual metric display with status indicators
- **Environment Filter**: Filter by environment
- **Real-time Updates**: Live metric updates
- **Auto-refresh**: Automatic data refresh every 30 seconds

## 🔄 Next Steps (Future Enhancements)

- [ ] Prometheus integration (replace simulated metrics)
- [ ] Grafana dashboards export
- [ ] Alert rules and thresholds
- [ ] Historical trend analysis
- [ ] Custom metric queries
- [ ] Service-specific dashboards
- [ ] Export metrics to CSV/JSON
- [ ] Metric comparison across environments
