summary

SIG Instrumentation defines Kubernetes metrics and logging interfaces, maintains kube-state-metrics (large-cluster optimizations) and the metrics-server used by kubectl top, and specifies resource/custom/external metrics APIs with adapter shims. A recent metrics overhaul deprecates old counters in 1.14 and removes them in 1.15; the Kubernetes mixin dashboards were updated to reduce breakage. Ongoing work adds static analysis to validate new metrics, evaluates a watch-enabled metrics API, explores structured logging, and plans trace instrumentation.
