Symfony event.DEBUG、doctrine.DEBUG、security.DEBUG使dev.log文件非常大

我在Symfony2上运行了一个应用程序。每当我加载一个页面或控制器时，dev.log文件中就会有成千上万的行：

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

随着时间的推移，这使得文件变得非常庞大，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

问题可能是什么以及如何解决？

在您的

config\u dev

部分的

monolog

中，将

debug

日志记录级别更改为更高级别，例如，

info

或“error”

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

您可能还希望设置

交叉手指

以保存调试消息，但只有在出现错误时，才会保存文档

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']

以忽略特定频道：“事件”、“信条”、“安全性”。

是我目前正在使用的，一点也不困扰我，这样我可以保留调试消息，以备需要，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。

谢谢，我刚刚这么做了，但它只删除了

event.DEBUG

<代码>条令.调试，

安全.调试

仍然存在@kabrice您现在使用的是什么级别？还有一个级别显示了如何禁用特定通道，我更喜欢它。我使用

level:debug

。另一方面，我担心如果我禁用这些通道（安全、事件等），我可能会错过一些有用的调试消息，因为所有调试消息都不是无用的。@kabrice这样，只有手指交叉筛选或定期删除才有帮助。
