SIG Instrumentation Introduction and Deep Dive

summary
SIG Instrumentation covers concrete work: it migrates Kubernetes to structured logging (kubelet moved in 1.21) with CI static checks to block non‑JSON logs and logging sanitization moving from alpha toward beta in 1.23. Control plane tracing is alpha with a 1% sampling demo using OpenTelemetry collector sidecars sending spans to Jaeger. Metrics work includes kube‑state‑metrics, the metric server and Prometheus adapter now under the SIG, a metric stability framework that freezes label schemas, and a metrics cardinality enforcement tool that bounds runtime label values via a restart flag.
