title: How do I reduce the severity of NotFoundHttpException?
body: <p>I want to be alerted when bad things happen in my Symfony2 app. Right now I just look for <code>ERROR</code> in the logs. Unfortunately, "HTTP 404 - file not found" (NotFoundHttpException) gets logged as an error, as does "HTTP 403 - forbidden" (AccessDeniedHttpException).</p>
  
  <p>This doesn't warrant an error; at the most these should be warnings. How can I make these log at a less severe level?</p>
  
  <p>Example error:</p>
  
  <pre><code>[2012-07-02 16:58:21] request.ERROR: Symfony\Component\HttpKernel\Exception\NotFoundHttpException: No route found for "GET /foo" (uncaught exception) at /home/user/Symfony2_v2.0.12/vendor/symfony/src/Symfony/Bundle/FrameworkBundle/EventListener/RouterListener.php line 83 [] []
  </code></pre>
