 ==============================
 
 By default the profile stores the collected data in files in the ``%kernel.cache_dir%/profiler/`` directory.
-You can control the storage being used through the ``dsn``, ``username``,
-``password`` and ``lifetime`` options. For example, the following configuration
-uses MySQL as the storage for the profiler with a lifetime of one hour:
-
-.. configuration-block::
-
-    .. code-block:: yaml
-
-        # app/config/config.yml
-        framework:
-            profiler:
-                dsn:      'mysql:host=localhost;dbname=%database_name%'
-                username: '%database_user%'
-                password: '%database_password%'
-                lifetime: 3600

-The :doc:`HttpKernel component </components/http_kernel/introduction>` currently
-supports the following profiler storage drivers:
-
-* file
-* sqlite
-* mysql
-* mongodb
-* memcache
-* memcached
-* redis
+You can control the storage by implementing the ``Symfony\Component\HttpKernel\Profiler\ProfilerStorageInterface`` in 
+your own service and override the ``profiler.storage`` service.
