Observability Beyond the three pillars with Spring

on YouTube ↗58m

" summary

Concrete claim: having logs metrics and traces is not enough — real observability needs meaningful outputs, quick ad hoc questions, and context propagation. Uses Spring Boot + Actuator, Micrometer (counters/gauges/timers), Logbook for payload logs, Zipkin/Brave or Prometheus backends, and OpenTelemetry support; demos include metrics showing 99.999th percentile latency to flag a slow DB call revealed by tracing. Announces Micrometer Tracing migration from Sleuth for Spring Boot 3 and shows the info endpoint shows build commit and JVM/container mismatches for debugging.
