核心概念
每个Logger实例都有一个通道和日志处理器栈。每当你添加一条日志记录,它会被发送到日志处理器栈。 你可以创建很多Logger,
每个Logger定义一个通道(db,请求,路由),每个Logger有很多日志处理器。这些通道会过滤日志。
每个日志处理器都有一个Formatter(内置的日志显示格式处理器)。你还可以设定日志级别。
日志级别
- DEBUG:详细的debug信息
- INFO:感兴趣的事件。像用户登录,SQL日志
- NOTICE:正常但有重大意义的事件。
- WARNING:发生异常,使用了已经过时的API。
- ERROR:运行时发生了错误,错误需要记录下来并监视,但错误不需要立即处理。
- CRITICAL:关键错误,像应用中的组件不可用。
- ALETR:需要立即采取措施的错误,像整个网站挂掉了,数据库不可用。这个时候触发器会通过SMS通知你,
