๐ก kube-state-metrics (KSM) Architectural Overview (Executive Summary)
kube-state-metrics (KSM) is a simple service that listens to the Kubernetes API server and generates metrics about the state of the objects (Deployments, Nodes, Pods, PVs, etc.) in Prometheus exposition format.
Unlike node-exporter (host CPU/memory metrics) or cAdvisor (container runtime resource usage), KSM focuses on orchestration object health, desired spec vs current status, condition flags, and replica counts.
๐๏ธ kube-state-metrics Data Flow & Scraping Architecture
KSM runs as a single cluster-wide Deployment (or with an HA replica) utilizing the official client-go Reflector/Informer caches to stream state metrics with zero API server load overhead.
