Spring Boot Observability

Priority: P0 (CRITICAL)

Implementation Workflow

1. Add tracing and metrics dependencies to pom.xml
2. Configure application.yaml for tracing, actuator, and log correlation
3. Add structured logging with MDC context
4. Verify with curl localhost:8080/actuator/prometheus and check trace IDs in logs

Enable Distributed Tracing

• Correlation IDs: Enable trace/span ID injection.
• Propagation: Propagate context across threads (@Async) and clients.
• OpenTelemetry: Use OTel bridge (micrometer-tracing-bridge-otel).

See implementation examples for application.yaml tracing configuration and actuator exposure.

Configure Structured Logging
