How to check Trace or log file in YII?

logging, php, yii

Solution

If you are using default Yii `main.php` file then all the logs go to your `protected/runtime/application.log` file. It will include standard Yii logs as well as you own `Yii::log()` calls too.

Problem

I Want to use log functionality from YII and i am new to YII. Can anyone guide me where is file location of logging content? or tracing content?
