|
* Router manages [[Target|log targets]] that record log messages in different media. |
|
* |
|
* For example, a [[FileTarget|file log target]] records log messages |
|
* in files; an [[EmailTarget|email log target]] sends log messages |
|
* to specific email addresses. Each log target may specify filters on |
|
* message levels and categories to record specific messages only. |
|
* |
|
* Router and the targets it manages may be configured in application configuration, |
|
* like the following: |
|
* |
|
* ~~~ |
|
* array( |
|
* // preload log component when application starts |
|
* 'preload' => array('log'), |
|
* 'components' => array( |
|
* 'log' => array( |
|
* 'class' => 'yii\logging\Router', |
|
* 'targets' => array( |
|
* 'file' => array( |
|
* 'class' => 'yii\logging\FileTarget', |
|
* 'levels' => array('trace', 'info'), |
|
* 'categories' => array('yii\*'), |
|
* ), |
|
* 'email' => array( |
|
* 'class' => 'yii\logging\EmailTarget', |
|
* 'levels' => array('error', 'warning'), |
|
* 'emails' => array('admin@example.com'), |
|
* ), |
|
* ), |
|
* ), |
|
* ), |
|
* ) |
|
* ~~~ |
|
* |
|
* Each log target can have a name and can be referenced via the [[targets]] property |
|
* as follows: |
|
* |
|
* ~~~ |
|
* Yii::$app->log->targets['file']->enabled = false; |
|
* ~~~ |
