title: Application performance management for PHP application
body: <p>I am looking for an application performance management for PHP (see <a href="http://en.wikipedia.org/wiki/Application_performance_management" rel="nofollow">http://en.wikipedia.org/wiki/Application_performance_management</a>)</p>
  
  <p>This tool could be plugged to any PHP application in production, and can collect/display statistic about PHP execution time, network time, db query time for each request. For each indicator, I would like to see the min, max and average value.</p>
  
  <p>All these statistics would be available in real time and also for the past.</p>
  
  <p>Is there any existing tool which can do that? Suggestion for any tools (free or not) are welcome.</p>
