# Metrics Server

Metrics Server provides the Kubernetes Metrics API for live resource usage,
including `kubectl top` and future HPA/VPA resource metrics.

It is intentionally small and not scraped by Prometheus. Prometheus/Grafana
remain the source for historical dashboards and alerting.

Talos kubelets use serving certificates that are not trusted by metrics-server
unless kubelet server certificate rotation and CSR approval are configured.
This deployment uses `--kubelet-insecure-tls` so it works with the current
Talos configuration.

After syncing, verify:

```bash
kubectl -n kube-system get deploy metrics-server
kubectl get apiservice v1beta1.metrics.k8s.io
kubectl top nodes
kubectl top pods -n litellm
```
