.. index:: pair: Monolog; Configuration reference Logging Configuration Reference (MonologBundle) =============================================== The MonologBundle integrates the Monolog :doc:`logging ` library in Symfony applications. All these options are configured under the ``monolog`` key in your application configuration. .. code-block:: terminal # displays the default config values defined by Symfony $ php bin/console config:dump-reference monolog # displays the actual config values used by your application $ php bin/console debug:config monolog .. note:: When using XML, you must use the ``http://symfony.com/schema/dic/monolog`` namespace and the related XSD schema is available at: ``https://symfony.com/schema/dic/monolog/monolog-1.0.xsd`` .. tip:: For a full list of handler types and related configuration options, see `Monolog Configuration`_. .. note:: When the profiler is enabled, a handler is added to store the logs' messages in the profiler. The profiler uses the name "debug" so it is reserved and cannot be used in the configuration. .. _`Monolog Configuration`: https://github.com/symfony/monolog-bundle/blob/master/DependencyInjection/Configuration.php
