## Integration Guidelines
|
||
|
||
### Minimal Integration
|
||
|
||
```python
|
||
from src.monitoring import SystemMonitor, WebDashboard
|
||
|
||
# Create monitor
|
||
monitor = SystemMonitor(update_rate_hz=10.0)
|
||
|
||
# Create dashboard
|
||
dashboard = WebDashboard(port=5000)
|
||
dashboard.set_system_monitor(monitor)
|
||
|
||
# Start monitoring
|
||
monitor.start()
|
||
dashboard.start(blocking=False)
|
||
```
|
||
|
||
### Full Integration
|
||
|
||
```python
|
||
from src.monitoring import (
|
||
SystemMonitor, DataValidator, AlertManager,
|
||
WebDashboard, create_default_rules
|
||
)
|
||
|
||
# Create all components
|
||
monitor = SystemMonitor(update_rate_hz=10.0, num_cameras=20)
|
||
validator = DataValidator()
|
||
alert_mgr = AlertManager(enable_auto_diagnostics=True)
|
||
dashboard = WebDashboard(port=5000)
|
||
|
||
# Configure alerts
|
||
alert_mgr.configure_email(...)
|
||
for rule in create_default_rules():
|
||
alert_mgr.add_rule(rule)
|
||
|
||
# Link components
|
||
monitor.set_camera_manager(camera_mgr)
|
||
monitor.set_tracker(tracker)
|
||
alert_mgr.set_system_monitor(monitor)
|
||
dashboard.set_system_monitor(monitor)
|
||
dashboard.set_alert_manager(alert_mgr)
|
||
dashboard.set_validator(validator)
|
||
|
||
# Start all services
|
||
monitor.start()
|
||
dashboard.start(blocking=False)
|
||
|
||
# Main processing loop
|
||
while True:
|
||
# Process frame
|
||
result = validator.validate_detection(detection)
|
||
if not result.passed:
|
||
# Handle validation failure
|
||
pass
|
||
|
||
# Check alert rules periodically
|
||
alert_mgr.check_rules(monitor.get_summary())
|
||
```
|
||
|
||
## Security Considerations
|
||
|
||
### Web Dashboard
|
||
- No authentication by default (add reverse proxy)
|
||
- Listen on localhost only for production
|
||
- Use HTTPS with proper certificates
|
||
- Rate limit API endpoints
|
||
- Sanitize all inputs
|
||
|
||
### Alert Notifications
|
||
- Store credentials securely (environment variables)
|
||
- Use app passwords for email
|
||
- Validate webhook URLs
|
||
- Encrypt sensitive data in transit
|
||
- Log all notification attempts
|
||
|
||
## Future Enhancements
|
||
|
||
### Planned Features
|
||
1. Machine learning-based anomaly detection
|
||
2. Predictive maintenance alerts
|
||
3. Historical trend analysis
|
||
4. Mobile app interface
|
||
5. Distributed monitoring across nodes
|
||
6. Advanced 3D visualization
|
||
7. Performance profiling tools
|
||
8. Automated remediation actions
|
||
|
||
### Scalability Improvements
|
||
1. Time-series database integration (InfluxDB)
|
||
2. Message queue for alerts (RabbitMQ)
|
||
3. Distributed tracing (OpenTelemetry)
|
||
4. Container orchestration (Kubernetes)
|
||
5. Load balancing for dashboard
|
||
|
||
## Conclusion
