Summary
This chapter comprehensively explored observability in modern software systems, emphasizing the importance of deep visibility across distributed architectures. You learned about the three pillars of observability—logs, metrics, and traces—and how they contribute to system performance monitoring and troubleshooting. The chapter also explained how to implement observability using tools such as ELK for centralized logging, Micrometer, OpenTelemetry for metrics, and Zipkin for distributed tracing.
In addition, the chapter introduced advanced topics such as APM with New Relic. It demonstrated how to integrate it to provide a complete view of application performance in a distributed environment, from logs to traces.
This chapter’s theoretical concepts and practical implication strategies provided insights into enhancing observability in distributed systems to improve application reliability and performance.
In Chapter 12, Testing, we will introduce and...
