<p>I have a Kubernetes 1.9.11 cluster on baremetal machines running Coreos 1576.5.0.</p>

<p>Recently I deployed a Glusterfs 4.1.7 cluster, managed by Heketi 8, and created a lot of PVCs to be used by some statfulset applications. The problem is, I can't get metrics about these PVCs through Kublet's 10250 port:</p>

<pre><code>curl -k https://aa05:10250/metrics 2&gt;/dev/null | grep kubelet_volume_stats | wc -l
0
</code></pre>

<p>So, how can I get these metrics?</p>

<p>Any hints will be appreciated.</p>

<p>It looks like kubelet is implementing metrics for volumes in <a href="https://github.com/kubernetes/kubernetes/blob/release-1.9/pkg/kubelet/metrics/metrics.go" rel="nofollow noreferrer">release-1.9.x</a>,but their naming is quite different from what you are grepping for. Try to grep for <code>volume_stats</code>.</p>
