title: How to reset MySQL performance reports?
body: <p>I'm trying to use the MySQL performance reports to try and find what is bottlenecking my read and write performance under special situations and It's cluttered up with loads of old statistics regarding other queries to my tables.</p>
  
  <p>I want to clear all the performance data so I can get a fresh look.</p>
  
  <p>The <code>Clear Event Tables</code> button doesn't actually seem to clear anything.</p>
  
  <p>How do I do this?</p>
