symfony - 如何在 Symfony2.2 中使用 Monolog 将消息记录到不同的文件？

Question

我想在 symfony2 应用程序中使用 Monolog 进行日志记录，但我的问题是如何每天拆分文件而不是附加到同一个文件？

我希望我的日志文件如下所示：

"%kernel.logs_dir%/%kernel.environment%.%date%.log" 其中 %date% 应替换为实际日期。

我读了那个 logrotate 但我不明白如何使用它？

Answer 1

Use multiple handlers

Example:

monolog:
    handlers:
        main:
            type:  stream
            path:  %kernel.logs_dir%/%kernel.environment%.log
            level: debug
        ex1:
            type:  stream
            path:  %kernel.logs_dir%/ex1.log
            level: info
        ex2:
            type:  stream
            path:  %kernel.logs_dir%/ex2.log
            level: error

It's explained in the Symfony2 Cookbook http://symfony.com/doc/current/cookbook/logging/monolog.html

And specific for you (channels): http://symfony.com/doc/current/cookbook/logging/channels_handlers.html

This will create a new file for each day. You can also define a max number of files.

monolog:
    handlers:
        main:
            type:       rotating_file
            path:       "%kernel.logs_dir%/%kernel.environment%.log"
            level:      notice
            max_files:  10

It will create a date to the file name automatically, so you don't have to worry about that.
