Observability
Metrics and logs both surface in Grafana, keeping dashboards and log queries in one place.
Metrics
kube-prometheus-stack runs in the prometheus namespace (ArgoCD-managed). Prometheus scrapes all nodes, pods, and control plane components. Grafana has dashboards for cluster overview, node resources, Longhorn, ArgoCD, and Traefik.
Node Exporter is deployed via Ansible on every VM including docker-host11 and the edge VPS, so coverage isn't limited to what's inside Kubernetes.
Goldilocks and VPA run alongside and analyze actual resource usage to suggest better request/limit values.
Alertmanager routes alerts to Ntfy via a custom webhook bridge.
Logs
Loki runs in the loki namespace (single-node, filesystem storage). Promtail runs as a DaemonSet and ships pod logs from every cluster node to Loki. Logs are queryable in Grafana alongside metrics.
