How to include the severity of a log in the e-mail subject?

问题

I'm using Monolog with Symfony2 and have configured a logging environment where everything is logged to file, and above a certain threshold are e-mailed to me. My config is below.

However, I have not been able to adjust the e-mail subject so that it changes based on the actual level of the log. The difference in response time, for say, a warning and a critical, would probably be different. Is there a way to do this?

monolog:
    handlers:
        main:
            type:  stream
            path:  %kernel.logs_dir%/%kernel.environment%.log
            level: debug
        mail:
            type:         fingers_crossed
            action_level: %logger_level%
            handler:      buffered
        buffered:
            type:    buffer
            handler: swift
        swift:
            type:       swift_mailer
            from_email: %logger_from_email%
            to_email:   %logger_to_email%
            subject:    Log  # I want the subject to include the log level somehow
            level:      debug

You can define two different handlers (or handler chains): one is activated by low level problems and the other by more serious issues. They have different subjects for the email they send. Something like:

monolog:
    handlers:
        mail_critical:
            type:         fingers_crossed
            action_level: critical
            handler:      buffered_critical
            bubble: false
        buffered_critical:
            type:    buffer
            handler: swift_critical
        swift_critical:
            type:       swift_mailer
            from_email: %logger_from_email%
            to_email:   %logger_to_email%
            subject:    CALL 911, YOUR SITE IS BURNING
            level:      critical
        mail_debug:
            type:         fingers_crossed
            action_level: debug
            handler:      buffered_debug
        buffered_debug:
            type:    buffer
            handler: swift_debug
        swift_debug:
            type:       swift_mailer
            from_email: %logger_from_email%
            to_email:   %logger_to_email%
            subject:    Just a normal error
            level:      debug

You can include %%level%% in the subject. It will add int.

Or you can add %%level_name%% it will add string of leg level name.

        swift:
        type:       swift_mailer
        from_email: '%env(ADMIN_EMAIL)%'
        to_email:   '%env(ADMIN_EMAIL)%'
        subject:    '[%kernel.environment%] [LEVEL CODE:%%level%%][LEVEL NAME:%%level_name%%] Some subject text! %%message%%'
        level:      error
        formatter:  monolog.formatter.html
        content_type: text/html
