<p>The <code>procstats</code> tool is used to analyze application memory usage over time (versus at a
particular snapshot in time, like <code>meminfo</code>). Its state dump displays statistics about every application’s runtime,
proportional set size (PSS) and unique set size (USS).</p>
<h2 id=input>Input</h2>
<p>To get application memory usage stats for the last three hours, in
human-readable form, run the following command:</p>
<pre class="devsite-terminal devsite-click-to-copy">
adb shell dumpsys procstats --hours 3
</pre>
<h2 id=output>Output</h2>
<p>As can be seen in the example below, percentages display what percentage of
time the application was running, while the numbers following show PSS and USS
as minPSS-avgPSS-maxPSS/minUSS-avgUSS-maxUSS over samples.</p>
