Why does Symfony still log to a dev.log file, even when I didn't define it in a loghandler?

Question

During the execution of Symfony Commands, I want to log messages to a different file. I have read the Symfony and Monolog documentation, and it should work like I describe here. (Note that I know messages from the 'doctrine', 'event', ... channels will still be logged by the main handler, but that doesn't matter for me) In my `config.yml`, I have this: ``` monolog: channels: [commandline] handlers: main: type: stream path: "%kernel.logs_dir%/%kernel.environment%.main.log" level: debug channels: [!commandline] commandline: type: stream path: "%kernel.logs_dir%/%kernel.environment%.commandline.log" level: debug channels: commandline stdout: type: stream path: "php://stdout" level: debug channels: commandline mail: type: stream action_level: alert handler: buffered_mail buffered_mail: type: buffer handler: swift swift: type: swift_mailer from_email: some@email.com to_email: some@email.com subject: "Something went wrong" level: alert ``` I'm expecting to have 2 log-files: `dev.main.log` a…

REMOVE `monolog.handlers.main`from `config_dev.yml`.

It usally contains `path: "%kernel.logs_dir%/%kernel.environment%.log"`

config _dev.yml (default)

```
monolog:
    handlers:
        main:   # <- remove this handler
            type:   stream
            path:   "%kernel.logs_dir%/%kernel.environment%.log" #<- logs/dev.log
            level:  debug
```

Remove the `main` handler from this config file.
