What is the exactly RUM do?
<p>I read a document from <a href="https://newrelic.com/docs/features/how-does-real-user-monitoring-work" rel="nofollow">https://newrelic.com/docs/features/how-does-real-user-monitoring-work</a> 
And in this code:</p>

<pre><code>&lt;script type="text/javascript"&gt;
  if (!NREUMQ.f) NREUMQ.f=function() {
   NREUMQ.push(["load",new Date().getTime()]);
   var e=document.createElement("script");
   e.type="text/javascript";e.async=true;e.src="https://d7p9czrvs14ne.cloudfront.net/11/eum/rum.js";
   document.body.appendChild(e);
   if(NREUMQ.a)NREUMQ.a();
 };
 if(window.onload!==NREUMQ.f){NREUMQ.a=window.onload;window.onload=NREUMQ.f;};
 NREUMQ.push(["nrf2","beacon-1.newrelic.com","api-key",appID,"cV5eEkBfCF1WRBgECFZEQwNAbwVBQ1peAgdGWF8IQR8LR1ZEQQgDRQ==",6,707, new Date().getTime()]);
 &lt;/script&gt;
</code></pre>
