Health API Implementation - June 21, 2025

Summary

Implemented comprehensive health monitoring APIs for all SuData scrapers to enable dashboard monitoring and system health tracking.

Changes Made

🆕 New Files Created

  1. apps/tiktok-scraper/health_api.py - Health monitoring API for TikTok scraper
  2. apps/youtube-scraper/health_api.py - Health monitoring API for YouTube scraper

🔧 Modified Files

  1. apps/telegram-scraper/README.md - Updated health monitoring documentation
  2. apps/tiktok-scraper/README.md - Added comprehensive health API documentation
  3. apps/youtube-scraper/README.md - Added health API monitoring section
  4. README.md - Updated main project monitoring documentation

📡 Health API Endpoints

Each scraper now provides:

  • GET /health - Basic service health status
  • GET /health/detailed - Detailed statistics and metrics
  • GET / - Service information and available endpoints

🚀 Service Ports

Service Port Health API Status
Telegram Scraper 3005 ✅ Working
TikTok Scraper 3000 ✅ Working
YouTube Scraper 3001 ✅ Available
Refinery Service 3004 ✅ Available
Dashboard 3003 ✅ Monitoring all services

📊 Health API Features

Each health endpoint provides comprehensive monitoring data:

  • Service Status: healthy/error/stopped
  • Statistics:
    • Monitored channels/streamers count
    • Recent output files (last 24 hours)
    • Recent error count from logs
    • File details (size, modification time, age)
  • Service Info: Version, uptime, configuration

🎯 Dashboard Integration

Updated dashboard service status monitoring:

  • 🟢 Green: Service running and healthy
  • 🟡 Amber: Service status unknown (health endpoint unavailable)
  • 🔴 Red: Service error or health check failed
  • ⚪ Gray: Service stopped

🔧 Technical Implementation

  1. FastAPI Framework: Used for all health APIs for consistency
  2. Structured Logging: Implemented with structlog for better monitoring
  3. Error Handling: Graceful handling of missing dependencies
  4. Statistics Calculation: Real-time file and log analysis
  5. JSON Response Format: Standardized response structure across all services

🧪 Testing

  • ✅ Telegram scraper health API tested and working
  • ✅ TikTok scraper health API tested and working
  • ✅ Dashboard integration verified and working
  • ✅ Service status monitoring updated and functional

📝 Documentation

  • ✅ Individual scraper README files updated with detailed health API documentation
  • ✅ Main project README updated with comprehensive monitoring section
  • ✅ Health endpoint examples and usage instructions provided
  • ✅ Dashboard integration documentation added

Impact

This implementation provides:

  1. Complete System Visibility: Dashboard can now monitor all services in real-time
  2. Automated Health Monitoring: No more manual service checking required
  3. Standardized Monitoring: Consistent health API across all services
  4. Better Debugging: Detailed statistics help identify issues quickly
  5. Production Readiness: Proper health checks for deployment monitoring

Next Steps

  1. Start YouTube scraper health API server: python health_api.py
  2. Verify all services show as healthy in dashboard
  3. Monitor system health through dashboard interface
  4. Use health endpoints for automated monitoring and alerting
