<p>A few questions:</p>
<ul>
<li>What format is this? I know it isn't JSON.</li>
<li>Can I use jq to parse/filter this data? I would like to get all metrics on the <code>coredns</code> container:</li>
</ul>

<p>You could convert your file to JSON using <a href="https://github.com/prometheus/prom2json" rel="nofollow noreferrer">https://github.com/prometheus/prom2json</a></p>
<p>Then it's jq all the way down, if you wish.  E.g. with your input:</p>
<pre><code>prom2json sample.prom | jq '
  .[] | .metrics |= map(select(.labels.container==&quot;coredns&quot;) )'
</code></pre>
<p>yields</p>
<pre><code>{
