How to exclude deprecation messages from logs in Symfony 4?

I have migrated an application from Symfony 3.4 to Symfony 4.4.

Now I have a lot of deprecations for each request/ Sf command (I can't fix that deprecations).

How can I exclude deprecations from the log for this Symfony App?

Solution

  • Exclude the php channel from the log handler:

    Eg. config/packages/prod/monolog.yaml:

    monolog:
    handlers:
        main:
            type:  stream
            path:  %kernel.logs_dir%/%kernel.environment%.log
            level: debug
            formatter: monolog.formatter.session_request
            channels:
             -  '!php' # <----------- add this line

    Leave deprecation messages in the dev mode though. You should be aware of the changes in upstream packages.

    PS. in newer Symfony versions you have to exclude the deprecation channel instead, i.e.:

    channels:
    - '!deprecation'
