Analyzing class yii\log\Logger

Logger records logged messages in memory and sends them to different targets if [[dispatcher]] is set.

A Logger instance can be accessed via Yii::getLogger(). You can call the method [[log()]] to record a single log message. For convenience, a set of shortcut methods are provided for logging messages of various severity levels via the [[Yii]] class:

• [[Yii::trace()]]
• [[Yii::error()]]
• [[Yii::warning()]]
• [[Yii::info()]]
• [[Yii::beginProfile()]]
• [[Yii::endProfile()]]

For more details and usage information on Logger, see the guide article on logging.

When the application ends or [[flushInterval]] is reached, Logger will call [[flush()]] to send logged messages to different log targets, such as [[FileTarget|file]], [[EmailTarget|email]], or [[DbTarget|database]], with the help of the [[dispatcher]].
