Cluster-side: - Deploy kube-state-metrics (kube-system) for cluster-state series. - Deploy node-exporter DaemonSet on all 7 nodes via the new monitoring ns (privileged PSS, hostNetwork, read-only host mounts). - Both managed by ArgoCD apps under home/cluster/argocd/apps/. Prometheus-side: - Replace direct pod-IP scraping (which can't reach the 10.244.0.0/16 pod network from outside the cluster) with API-server-proxy scraping for both Services and Pods. Now one target per pod, all healthy. - Extend external Prometheus RBAC with services/proxy + pods/proxy. Grafana-side: - Add file-based dashboard provisioner; ship 5 standard dashboards (Node Exporter Full, k8s cluster-via-prometheus, k8s all-in-one, k8s monitoring, Prometheus 2.0 overview). prom.w5isp.com:3000 now shows live data for all 7 cluster nodes plus the prom host itself.
