title: How to read output of varnishtop?
body: <p>Using varnish-cache, I am running <code>varnishtop -c -i RxURL</code> to show number of client requests from the cache. The output looks somewhat like this:</p>
  
  <pre><code>list length 40                                                                                                                                                    
  
     121.76 RxURL          /some/path/to/file
     105.17 RxURL          /some/other/file
      42.91 RxURL          /and/another
      14.61 RxURL          /yet/another
      14.59 RxURL          /etc
      13.63 RxURL          /etc/etc
  </code></pre>
  
  <p>What do the numbers <code>121.76</code>, <code>105.17</code> etc. stand for?</p>
  
  <p>They are increasing when first issuing <code>varnishtop</code>, but then they tend to stabilize, so I tend to believe the represent number of hits per specific timeframe. Is that so, and what is the timeframe?</p>
  
  <p>This is not explained in the <code>man page</code>. Thank you for any assistance!</p>
  
  <p><strong>Edit</strong>: varnish version is <code>2.1</code></p>
