inanzzz | Accessing monolog service to create logs in symfony

This example creates two different channels for two different log files and both will be dedicated to their own controllers.

Add monolog bundle to composer.json

"require": {
    "symfony/monolog-bundle": "~2.4"
}

Update composer

composer update symfony/monolog-bundle

Update config.yml

monolog:
    channels: ["student", "subject"]
    handlers:
        student:
            type: stream
            path:  %kernel.logs_dir%/%kernel.environment%_student.log     # Creates dev_student.log file
            channels: ["student"]     # Force to handle only student channel
        subject:
            type: stream
            path:  %kernel.logs_dir%/%kernel.environment%_subject.log     # Creates dev_subject.log file
            channels: ["subject"]     # Force to handle only subject channel
        main:
            channels: ["!student", "!subject"]     # Force main channel to ignore student and subject channels
        console:
            channels: ["!doctrine", "!student", "!country"]     # Force console channel to ignore student and subject channels as well
