Question

我在Symfony2上运行一个应用程序。每当我加载页面或控制器时，dev.log 文件都会用这些行填充成千上万：

[2017-10-12 15:26:08] event.DEBUG: Notified event "kernel.response" to listener "SymfonyBridgeMonologHandlerFirePHPHandler::onKernelResponse". [] []

...thousands and thousands of the kind of same lines

随着时间的推移，这使得文件非常非常大，而且非常烦人。

这是我的 config_dev.yml 文件：

imports:
    - { resource: config.yml }
framework:
    router:   { resource: "%kernel.root_dir%/config/routing_dev.yml" }
    profiler: { only_exceptions: false }
web_profiler:
    toolbar: true
    intercept_redirects: false
monolog:
    handlers:
        main:
            type:  stream
            path:  %kernel.logs_dir%/%kernel.environment%.log
            level: debug
        firephp:
            type:  firephp
            level: info
#        chromephp:
#            type:  chromephp
#            level: info
assetic:
    use_controller: true
#swiftmailer:
#    delivery_address: [e-mail]

可能是什么问题以及如何摆脱？

Answer 1

在config_dev 第 monolog 节中，将日志记录级别更改为debug更高级别，例如 info 或"错误"。

monolog:
  handlers:
    main:
        type: stream
        path: '%kernel.logs_dir%/%kernel.environment%.log'
        level: debug
        channels: ['!event']

您可能还希望设置fingers_crossed来保存调试消息，但仅当发生错误时，此处是文档。

另一种方法是禁用特定的错误日志记录通道。在channels下添加['!event', '!doctrine', '!security']以忽略特定渠道："事件"、"学说"、"安全"。

Answer 2

我会保持调试选项处于启用状态，我将使用文件轮换：

# app/config/config_dev.yml
monolog:
    handlers:
        main:
            type:  rotating_file
            path:  '%kernel.logs_dir%/%kernel.environment%.log'
            level: debug
            # max number of log files to keep
            # defaults to zero, which means infinite files
            max_files: 10

是我目前正在使用的，根本不打扰我，这样我就可以保留调试消息以备不时之需和固定数量的文件。

或。。。。如果您愿意，可以混合使用这两种解决方案。
