<p>I installed Istio 1.6, using <em><strong>istioctl install --set profile=demo</strong></em>.
But I could only couple of metrics related to Kubernetes nodes. I can see configuration related Kubernetes Node:</p>
<pre><code>kubernetes_sd_configs:
  - role: node   relabel_configs:
  - action: labelmap
    regex: __meta_kubernetes_node_label_(.+)
  - target_label: __address__
    replacement: kubernetes.default.svc:443
  - source_labels: [__meta_kubernetes_node_name]
    regex: (.+)
    target_label: __metrics_path__
    replacement: /api/v1/nodes/${1}/proxy/metrics
</code></pre>
<p>Do I need to install node exporter daemonset?</p>
<p>Thanks</p>

<p>You must have missed some step. I reproduced and it is looking good on my end.
<br></p>
<p><strong>Double check this steps:</strong></p>
<p>Verify that the Prometheus service is running in the cluster:</p>
<pre><code>$ kubectl -n istio-system get svc prometheus
</code></pre>
<p>Launch the Prometheus UI</p>
<pre><code>istioctl dashboard prometheus
</code></pre>
<p>Execute a Prometheus query(click <kbd>Execute</kbd>  ). E.g.:</p>
<pre><code>istio_requests_total
</code></pre>
<p>Generate some traffic against the product page:</p>
<pre><code>export INGRESS_HOST=$(minikube ip)
export INGRESS_PORT=$(kubectl -n istio-system get service istio-ingressgateway -o jsonpath='{.spec.ports[?(@.name==&quot;http2&quot;)].nodePort}')
export GATEWAY_URL=$INGRESS_HOST:$INGRESS_PORT

curl http://$GATEWAY_URL/productpage
</code></pre>
<hr />
<p><strong>Edit:</strong> for node metrics</p>
<p>Yes, you are right: node exporter is not included.<br />
Fastest way to add it manually is using Helm(literally one line after helm is prepared):</p>
<pre><code>// Install helm
curl -L https://git.io/get_helm.sh | bash

// Install tiller
helm init

// Deploy node-exporter
helm install stable/prometheus-node-exporter

// Launch prometheus
istioctl dashboard prometheus

// Or even better, grafana
istioctl dashboard grafana
</code></pre>
<p>If you are using grafana, you can import dashboard ID: 11074 for a fancy display of the data gathered from node exporter:</p>
