event.DEBUG、doctrine.DEBUG、security.DEBUG 使 dev.log 文件变得非常大

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：

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

这使得文件随着时间的推移变得非常非常大，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: me@example.com

可能是什么问题以及如何解决？

Answer 1

在您的config_dev 部分monolog 中，将debug 日志记录级别更改为更高级别，例如info 或“错误”。

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

您可能还想设置fingers_crossed 来保存调试消息，但只有在发生错误时，here 才是文档。

另一种方法是禁用特定的错误记录通道。 在channels 下添加['!event', '!doctrine', '!security'] 以相应地忽略特定渠道：“事件”、“教义”、“安全”。

Answer 2

我会让调试选项保持启用状态，我会选择File Rotation：

# 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

这是我目前使用的，完全不会打扰我，这样我可以保留调试消息以备不时之需，并保留固定数量的文件。

或者..如果您愿意，您可以混合使用这两种解决方案。
