Microservice pattern: Exception tracking

Description

The Exception Tracking design pattern in microservices architecture involves the centralized handling and logging of exceptions that occur across different services. This pattern is essential for monitoring, debugging, and maintaining the health of a distributed system by providing a unified view of errors and their origins.

Main Elements of the Pattern:

1. Centralized Exception Logger: A dedicated service or tool that aggregates and stores exception data from various microservices.
2. Exception Handling Middleware: Middleware components in each microservice that catch and forward exceptions to the centralized logger.
3. Correlation ID: Unique identifiers that help trace the flow of requests and corresponding exceptions across multiple services.
4. Alerting and Monitoring: Integration with monitoring tools to alert the development and operations teams about critical issues in real-time.
5. Dashboard: A user interface that provides insights and analytics on exceptions, including frequency, severity, and potential impact.

Acceptance Criteria

• Implement a centralized exception logger service that aggregates exception data from all microservices.
• Develop middleware components for each microservice to catch and forward exceptions to the centralized logger.
• Implement correlation IDs to trace the flow of requests and exceptions across microservices.
• Integrate the centralized logger with monitoring and alerting tools to notify the team of critical issues.
• Create a dashboard to visualize and analyze exception data, providing insights on frequency, severity, and impact.

The issue names no repository files, tests, or entry points, so first inspect the project structure and existing microservice or logging patterns. Compare the proposed centralized logger, middleware, correlation IDs, monitoring integration, and dashboard with the repository's scope. Done means all five acceptance criteria are implemented and verified across the relevant services.
