<p>POD consist: <code>my-app-container</code> and <code>envoy (istio-proxy)</code> container</p>
<p>I want to get <code>cpu_usage</code> of <code>envoy-container</code> from <code>may-app-container</code>.</p>
<p>Info from: <code>http://localhost:1500/stats</code> and <code>http://localhost:1500/stats/prometheus</code> doesn't contain <code>CPU_usage</code>.</p>
<p>Thanks</p>

<p>Below are 2 ways I could find to get the information about istio-proxy cpu usage.</p>
