Summary
In this chapter, we explored the core components and best practices for achieving effective monitoring and observability in RESTful services. Beginning with logging, we discussed the importance of structured logging for API troubleshooting, log levels to indicate severity, and correlation IDs to link requests across services. By implementing these logging practices centrally, such as with a filter in Spring Boot, we ensured consistent and secure logging across the application.
We then introduced distributed tracing, explaining how traceId, spanId, and parentSpanId create a parent-child relationship among services, allowing developers to track the journey of requests through a system.
Micrometer Tracing was covered as a key tool in Spring Boot 3.x for enabling and managing distributed tracing. It automatically instruments Spring Boot applications, capturing trace and span information for each request.
Micrometer Tracing integrates with multiple exporters, including...
