title: Why container memory usage is doubled in cAdvisor metrics?
body: <p>I tested those queries. The first query was half the value of the second query:</p>
  <p><code>sum(container_memory_working_set_bytes{image!=&quot;&quot;,name=~&quot;^k8s_.*&quot;,pod=~&quot;$pod&quot;}) by (pod)</code></p>
  <p>and</p>
  <p><code>sum (container_memory_working_set_bytes{pod=~&quot;$pod&quot;}) by (pod)</code></p>
  <p>Why is writing <code>image! = &quot;&quot;, name = ~ &quot;^ k8s_. *&quot;</code> Halving the value?</p>
