PHP 8.2
Symfony 7.2.3
Monolog 3.10.0

Hello, I'm using monolog with Symfony.
I configured the "main" log for rotation, but it seems rotation never happens.
Here's the config I put in monolog.yaml to configure the service :

when@dev:
    monolog:
        handlers:
            main:
                type: rotating_file
                path: "%kernel.logs_dir%/%kernel.environment%_main.log"
                level: debug
                channels: [ "!security", "!audit" ]
                max_files: 30
            security:
                type: rotating_file
                path: "%kernel.logs_dir%/%kernel.environment%_security.log"
                level: debug
                channels: [ "security" ]
                max_files: 10
            audit:
                type: rotating_file
                path: "%kernel.logs_dir%/%kernel.environment%_audit.log"
                level: debug
                channels: [ "audit" ]
                max_files: 10

For security and audit handlers, everything is ok. I've got log files each day, with names like "dev_audit-YYYY-MM-DD.log" or "dev_security-YYYY-MM-DD.log". Same configuration is done for "main" handler, but the logs never rotates. And I saw that the log file is called "dev.log", and not "dev_main.log" as configured.

Do you see anything I missed in the configuration please ?

Thank you.

Do you have other configuration in your project that may be overriding the configuration of your main handler ? That's the only explanation I see for that behavior.

I don't know really. For me, the only configuration is in this yaml file, and before the code I mentionned earlier, I've just the declaration of a new channel :

monolog:
    channels: ['audit']

This shouldn't interfere with the main handler, for what I understand.

Sorry this was a silly question. I've just found I have "monolog.yaml" file in "packages/dev", in "packages/prod" and directly in "packages"...

Just a last question about this : what is recommended ?

One file in "packages"
Each file in the dev/prod/test sub-folder ?

IMO all in one monolog.yaml is clearer so you have the overview and are less likely to do such mistakes.. when@dev: syntax lets you split env specific configs in the same file already.
