fierzone Spring Boot Observability
Priority: P0
Implementation Guidelines
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).
Structured Logging
- Format: Use JSON logging (
logstash-logback-encoder) in production. - MDC: Use MDC for contextual info (userId, tenantId).
- Output: Log to stdout only. Let container handle shipping.
Actuator
- Security: Secure
/actuator/**with Admin role. - Probes: Enable K8s Liveness/Readiness probes.
Anti-Patterns
- System.out:
**No System.out**: Use Slf4j. - Public Actuator:
**No Open Actuator**: Secure endpoints. - Custom Tracing:
**No DIY Tracing**: Use Micrometer.
