🚦 Smart Intersection MQTT + InfluxDB + Grafana Integration

COMPLETE IMPLEMENTATION SUMMARY

Based on my analysis of the qt_app_pyside1 project, I've implemented a comprehensive hybrid desktop + services architecture that adds professional-grade monitoring and analytics capabilities.

---

✅ WHAT HAS BEEN IMPLEMENTED

1. Service Infrastructure

• ✅ MQTT Broker (Mosquitto) - Real-time event streaming
• ✅ InfluxDB v2 - Time series database for metrics
• ✅ Grafana - Professional dashboards and visualization
• ✅ Docker Compose - Easy containerized deployment
• ✅ Windows Services - Native installation support

2. Desktop Application Integration

• ✅ Enhanced Smart Intersection Controller - MQTT/InfluxDB publishing
• ✅ Service Status Widget - Real-time service monitoring
• ✅ Async MQTT Publisher - Non-blocking event publishing
• ✅ InfluxDB Writer - Time series data storage
• ✅ Health Monitoring - Service availability checking

3. Configuration System

• ✅ Service Configuration - Centralized service settings
• ✅ MQTT Topics Schema - Structured event definitions
• ✅ Grafana Datasources - Pre-configured connections
• ✅ Dashboard Templates - Ready-to-use analytics views

4. Automation & Setup

• ✅ Automated Setup Script - One-click installation
• ✅ Startup/Shutdown Scripts - Service management
• ✅ Health Checks - Service availability testing
• ✅ Graceful Degradation - Works without services

📋 STEP-BY-STEP IMPLEMENTATION GUIDE

Phase 1: Install Required Dependencies

# Install Python packages
cd qt_app_pyside1
pip install -r requirements.txt

# New packages added:
# - paho-mqtt==1.6.1          # MQTT client
# - influxdb-client==1.43.0   # InfluxDB v2 client  
# - grafana-api==1.0.3        # Grafana API client
# - aiohttp==3.9.1            # Async HTTP
# - asyncio-mqtt==0.13.0      # Async MQTT

Phase 2: Setup Services (Choose One Method)

Method A: Docker Compose (Recommended)

# Start all services
cd services/docker
docker-compose up -d

# Services will be available at:
# - MQTT: localhost:1883
# - InfluxDB: localhost:8086  
# - Grafana: localhost:3000

Method B: Automated Setup

# Run the setup script
cd services/scripts
python setup_services.py

# Follow the interactive setup process
# Downloads and configures all services automatically

Method C: Manual Installation

1. Download Software:

   • Mosquitto: https://mosquitto.org/download/
   • InfluxDB: https://portal.influxdata.com/downloads/
   • Grafana: https://grafana.com/grafana/download?platform=windows

2. Install & Configure:

   • Follow individual installation guides
   • Copy configuration files from services/ directories

Phase 3: Start Services

# Use provided startup script
cd services/scripts
start_services.bat

# Or manually start each service
# Mosquitto: C:\Program Files\mosquitto\mosquitto.exe -c mosquitto.conf
# InfluxDB: C:\InfluxDB\influxd.exe --config config.yml  
# Grafana: C:\Grafana\bin\grafana-server.exe

Phase 4: Configure Desktop Application

The desktop app will automatically:

• ✅ Detect running services
• ✅ Connect to MQTT broker
• ✅ Initialize InfluxDB connection
• ✅ Show service status in UI
• ✅ Publish real-time events
• ✅ Store metrics in time series database

🔧 SERVICE CONFIGURATION

MQTT Topics Structure

{
  "smartintersection/detection": "Real-time object detection",
  "smartintersection/violations": "Traffic violations",  
  "smartintersection/performance": "System metrics",
  "smartintersection/traffic/flow": "Traffic flow data",
  "smartintersection/safety/pedestrian": "Safety events",
  "smartintersection/roi/events": "ROI-based events",
  "smartintersection/system/health": "System status"
}

InfluxDB Measurements

performance         # FPS, GPU usage, processing time
detection_events    # Object counts, confidence levels
violation_events    # Traffic violations by type
traffic_flow        # Vehicle counts, speeds, congestion
roi_events          # Region-based analytics
system_health       # Overall system status

Grafana Dashboards

• 📊 Real-time Monitoring - Live traffic analytics
• ⚡ Performance Metrics - System health and FPS

📊 RESOURCE USAGE

Service	RAM Usage	CPU Usage	Disk Space
Mosquitto	5-10 MB	<1%	50 MB
InfluxDB	50-100 MB	2-5%	200 MB + data
Grafana	100-150 MB	1-3%	300 MB
Total	200-300 MB	3-8%	550 MB

🚀 QUICK START

1. Start Services (2 minutes)

cd qt_app_pyside1/services/scripts
start_services.bat

2. Launch Desktop App (1 minute)

cd qt_app_pyside1
python main.py

3. Access Dashboards (30 seconds)

• Grafana: http://localhost:3000 (admin/admin)
• InfluxDB: http://localhost:8086
• Service Status: Check desktop app "Services" tab

---

🛠️ TROUBLESHOOTING

Common Issues:

1. Services not starting:

   • Check Windows Firewall settings
   • Run startup script as Administrator
   • Verify port availability (1883, 8086, 3000)

2. Desktop app can't connect:

   • Ensure services are running (netstat -an | findstr :1883)
   • Check service configuration files
   • Review service logs in services/logs/

3. Grafana dashboards empty:

   • Wait 2-3 minutes for data to populate
   • Check InfluxDB connection in Grafana
   • Verify MQTT messages are being published

Service Health Check:

# Test service ports
telnet localhost 1883  # MQTT
telnet localhost 8086  # InfluxDB  
telnet localhost 3000  # Grafana
