Hi,

Symfony documentation says only 500 pages are profiled if only_exception is set.

But it's wrong. All exceptions are stored, it don't take status_code in consideration to profile and i would like to know if it's a valid use case (btw i'll make a pr on symfony-docs) or a bug.

If it's a bug i can make a PR to fix it.

In this method

https://github.com/symfony/symfony/blob/master/src/Symfony/Component/HttpKernel/EventListener/ProfilerListener.php#L89 we could check for $event->getResponse()->getStatusCode() and store only 5xx

OR

To stay BC, introduce a status_codes into framework.profiler configuration.
