You can change the channel monolog logs to one service at a time. This is done

by tagging your service with ``monolog.logger`` and specifying which channel

the service should log to. By doing this, the logger that is injected into

that service is preconfigured to use the channel you've specified.

For more information - including a full example - read ":ref:`dic_tags-monolog`"

in the Dependency Injection Tags reference section.

either via the:ref:`configuration<cookbook-monolog-channels-config>` below

or by tagging your service with:ref:`monolog.logger<dic_tags-monolog>` and

specifying which channel the service should log to. With the tag, the logger

that is injected into that service is preconfigured to use the channel you've

specified.

Configure Additional Channels without Tagged Services

..versionadded::2.3

Since Symfony 2.3 you can install MonologBundle 2.4 to be able to configure

additional channels in the configuration.

This feature was introduced to the MonologBundle in version 2.4. This

version is compatible with Symfony 2.3, but only MonologBundle 2.3 is

installed by default. To use this feature, upgrade your bundle manually.

With MonologBundle 2.4 you can configure additional channels without the

need to tag your services:

With this, you can now send log messages to the ``foo`` channel by using

the automically registered logger service ``monolog.logger.foo``.

the automatically registered logger service ``monolog.logger.foo``.
