2. Metric Analysis:

   • User selects a specific metric
   • Views detailed breakdown and historical data
   • Applies filters (date range, team, project)
   • Exports or shares findings

3. Alert Configuration:

   • User accesses alert settings
   • Defines metric thresholds
   • Selects notification method (email, Slack, etc.)
   • Sets up recurring or one-time alerts

Technical Specifications

8. Configure automated backups for database and critical data
9. Implement auto-scaling based on load metrics
10. Set up a content delivery network (CDN) for static assets

Design Rationale

The Codebase Metrics Dashboard is designed with scalability, performance, and user experience in mind. React is chosen for its component-based architecture, allowing for reusable and maintainable UI elements. Node.js and Express provide a lightweight and efficient backend, while PostgreSQL offers robust data storage for complex metrics relationships.

The microservices architecture allows for independent scaling of different components, such as data collection and processing. Redis is used for caching and real-time updates to ensure responsiveness even with large datasets.

The customizable dashboard approach caters to different user roles and preferences, enhancing the tool's versatility. Integration with popular development tools ensures broad applicability across various development environments.

Security is prioritized through role-based access control and secure API design. The deployment strategy focuses on reliability and ease of updates, utilizing modern DevOps practices for continuous delivery and monitoring.
