how to make symfony2 writes log in prod mode?

[mappedinn]

I would like to make symfony writes in the file app/logs in prod mode.
To do so, I changed the config of monolog in config_prod.yml

monolog:
    handlers:
        main:
            type:         fingers_crossed
            action_level: error
            handler:      nested
        nested:
            type:  stream
            path:  %kernel.logs_dir%/%kernel.environment%.log
            level: debug

But, not prod.log file is generated!

Since the log is produced in dev mode, I copied than the monolog config which is available in config_dev.yml to the config_prod.yml. This config is follows:

monolog:
    handlers:
        main:
            type:  stream
            path:  %kernel.logs_dir%/%kernel.environment%.log
            level: debug
        firephp:
            type:  firephp
            level: info
        chromephp:
            type:  chromephp
            level: info

But, still no prod.log is written in prod mode.

Is there any idea?

For your information , I am using symfony 2.3.11.

the first config you pasted means that logs are written only when a message at the error level at least is logged (this is the goal of the FingersCrossedHandler: avoiding logging when everything is fine)

Have you thought about clearing your prod cache when changing the logging configuration ? If no, it is logical that you don't see any change, as Symfony does not reload the config automatically in the prod environment

Nothing changed!

What I have not noticed is that in prod mode symfony displays white page!

I noticed that only today because I working on a REST api so all my work (these days) consist only trying curl command.

NB : in prod mod all curl command give 500 error code!

@mappedinn is it possible that you have a fatal error of some sort? Have you checked the php error log? Because monolog might not log at all if the php process does not terminate correctly.

@Seldaek This is the case! I will try to see what to do!

I don't what it is the problem.

I returned back to a previous version of my project & prod.log is written now!

Thank your help!
