Release with confidence: Observability for microservices
summary
Demo shows a Kubernetes-hosted Spring Pet Clinic microservices stack (with added Kafka) instrumented by an Instana agent daemonset deployed via Helm that byte-instruments JVMs and collects traces metrics and logs without code changes. Distributed traces use distributed tracing headers to build request-scoped Gantt charts tying slow DB queries to the get-owners endpoint. Deploying a pagination fix reduces P99 latency from about 9,800 ms to ~3,319 ms, confirming the change works in the demo. request-scoped aggregation
