I want to log only the deprecated warnings to a new file. But I can't see how to achieve that with monolog. Is there a custom configuration?

Thanks in advance!

All Deprecated Message are logged As INFO level, php Channels so if You try this configuration All deprecation message will be logged in one file

monolog:
    handlers:
        security:
            level:    INFO
            type:     stream
            path:     '%kernel.logs_dir%/deprecated.log'
            channels: [php]

  • Works like a charm. I will try the same on production. – Rodrigo Santellan Jun 12 '17 at 14:30

    This will catch *all* messages in the `php` channel, not only the deprecations. For example, this will also include uncaught exceptions during the rendering of a twig template. – Maurice Dec 18 '19 at 13:57
