<p>I have installed Docker v1.13 and Kubernetes with Kubeadm v1.6. Then I installed Web UI (Dashboard). I can access it but its missing CPU/Memory usage graphs... Why could this happen? </p>

<p>For me the usage graphs worked once I installed <a href="https://github.com/kubernetes/heapster" rel="nofollow noreferrer">heapster</a> as an addon. Heapster requires an influxdb as data sink for the metric storage. Luckily you can deploy all those easily in k8s with the following definitions in the <code>kube-system</code> namespace (tested it with k8s <a href="https://github.com/kubernetes/kubernetes/releases/tag/v1.4.6" rel="nofollow noreferrer">1.4.6</a>): </p>
