summary

Starts at the Kubernetes API level with concrete tools like k9s and web UIs (Headlamp, Lens replacements) and demos kubectl debug attaching a shell into a distroless container; covers cluster metrics with Prometheus & Grafana; compares pod-sidecar service meshes that capture request/latency flows versus node-level capture using eBPF (Hubble/Cilium) to reduce agent count; drills into application traces and JVM auto- and javaagent instrumentation using OpenTelemetry, with live demos of traces, JVM metrics and SQL spans.
