<p>I have configured the Node Exporter in Kubernetes and start monitoring using Prometheus, But in Prometheus all servers are showing as down with the error below:</p>

<blockquote>
  <p>Get <a href="http://10.7.17.11:9100/metrics" rel="nofollow noreferrer">http://10.7.17.11:9100/metrics</a>: dial tcp 10.7.17.11:9100:
  getsockopt: connection timed out</p>
</blockquote>

<p>Can anyone help why it is showing down ?</p>

<p>Make sure firewall is not blocking port 9100. 
Try to curl this URL from other nodes and from the prometheus pod</p>
