Improve Monitoring and Observability for Kubernetes with OSS Tools
summary
A five‑microservice financial demo runs 500 Postman iterations and shows real‑time logs, metrics and traces: Loki for logs collects app and node logs into Grafana, revealing a burst that includes a reported 44 error; Prometheus + Grafana come from the kube‑prometheus‑stack Helm chart with ServiceMonitor CRDs for metrics; Jaeger tracing captures multi‑span calls. OpenTelemetry ties everything together with Java auto‑instrumentation and the demo dashboards and traces all work live.
