用于电子邮件和文件日志记录的 Symfony2 Monolog 设置

我想设置 Symfony2 向我发送电子邮件critical错误，但只需记录error级别错误。下面的设置可以做到这一点吗？

monolog:
    handlers:
        main:
            type:         fingers_crossed
            action_level: error
            handler:      grouped
        grouped:
            type: group
            members: [filelog, mail]
        # log all errors to file
        filelog:
            type:         fingers_crossed
            action_level: error
            handler:      nested_stream
        nested_stream:
            type:  stream
            path:  "%kernel.logs_dir%/%kernel.environment%.log"
            level: debug
        # send me an email when we have a critical error
        mail:
            type:         fingers_crossed
            action_level: critical
            handler:      buffered
        buffered:
            type:    buffer
            handler: swift
        swift:
            type:       swift_mailer
            from_email: %mailer_sender%
            to_email:   %error_email%
            subject:    "[FeedStream Error]"
            level:      debug

I saw: http://symfony.com/doc/current/cookbook/logging/monolog_email.html http://symfony.com/doc/current/cookbook/logging/monolog_email.html但它不处理error无论如何，在这种情况下我仍然想要日志（但不需要电子邮件）。我很确定我的配置可以工作，但我对独白设置了解不够。请告诉我这是否正确或是否有更好的方法。

以下是我的生产独白配置。已确认可以发送严重错误，同时将“错误”级别及以上级别记录到文件中。我还分割了不同的通道来单独的文件。其他渠道产生的错误似乎远少于“请求”，因此对我来说，在生产中将它们分开是有意义的。意识到这不是你的问题，但希望它对其他人有帮助；这可以减少以满足大多数要求。
