@javiereguiluz Thanks for adding this :). I think we should move this to a whole new section - with a header like How to Rotate your Log Files so it can be easily found. OR, make a new, very-short cookbook entry (to be even easier to find).

Thanks!

the special ``rotating_file`` handler defined by Monolog. This handler creates
a new log file every day and can also remove old files automatically. To use
it, just set the ``type`` option of your handler to ``rotating_file``:

.. code-block:: yaml

# app/config/config_dev.yml
monolog:
handlers:
main:
type: rotating_file # <-- this value is usually 'stream'
path: %kernel.logs_dir%/%kernel.environment%.log
level: debug

<?xml version="1.0" charset="UTF-8" ?>
<container xmlns=''http://symfony.com/schema/dic/services"
    xmlns:monolog="http://symfony.com/schema/dic/monolog">

    <monolog:config>
        <monolog:handler name="main"
            type="rotating_file"
            path="%kernel.logs_dir%/%kernel.environment%.log"
            level="debug"
        />
    </monolog:config>
</container>
// app/config/config_dev.php
$container->loadFromExtension('monolog', array(
    'handlers' => array(
        'main' => array(
            'type'  => 'rotating_file',
            'path'  => '%kernel.logs_dir%/%kernel.environment%.log',
            'level' => 'debug',
        ),
    ),

Thanks for reminding me about this! Done in 7345c17.


A processor is simply a callable receiving the record as its first argument.
Processors are configured using the ``monolog.processor`` DIC tag. See the
:ref:`reference about it <dic_tags-monolog-processor>`.
