Monitoring and Observability
Monitoring and observability are fundamental to ensuring that RESTful services operate reliably, efficiently, and securely. In distributed systems, where requests often pass through multiple services and components, having proper observability practices in place is critical. Without them, diagnosing performance bottlenecks, identifying the root causes of errors, and optimizing service behavior becomes incredibly challenging.
In this chapter, we will guide you through the essential practices and tools needed to achieve effective observability for RESTful services. We will begin by discussing logging best practices, explaining how structured logging and correlation IDs can simplify troubleshooting. We will then delve into distributed tracing, demonstrating how trace information such as traceId, spanId, and parentSpanId helps map the lifecycle of a request as it flows across multiple services.
We will introduce Micrometer Tracing, a powerful observability...
