  • Pushgateway: Support for short-lived jobs like pipeline stages

Application Enhancements

  • Metrics Endpoint: Added /metrics endpoint to Flask application
  • Prometheus Client: Integrated Prometheus client library for metric collection
  • Request Metrics: Tracking of HTTP requests, durations, and response codes
  • Rate Limit Metrics: Monitoring of rate limiting events and remaining capacity
  • Application Info Metrics: Uptime, version, and general app information

CI/CD Pipeline Enhancements

  • Pipeline Metrics: Track build durations, success rates, and stage performance
  • Jenkins Prometheus Plugin: Jenkins metrics exposure via Prometheus plugin
  • Metrics Collection Functions: Added utility functions to record pipeline metrics
  • Build Status Monitoring: Real-time monitoring of pipeline execution

Dashboards & Visualization

  • Flask Application Dashboard: Real-time monitoring of application performance
  • Jenkins Pipeline Dashboard: Pipeline execution statistics and trends

  • Updated README with monitoring capabilities
  • Added dashboard usage instructions
  • Included metrics testing and validation guides

Upgrade Instructions

  1. Pull the latest code with git pull origin main
  2. Run make all to recreate Docker services with monitoring components
  3. Access Prometheus at http://localhost:9090
  4. Access Grafana at http://localhost:3000 (default credentials: admin/admin)
  5. Run the monitoring test script: bash srcs/requirements/Scripts/test_monitoring.sh
