'yii2 how to view the logs of another .log file

I am using the yii2 framework with the 'queue' extension. This extension may fail, which is saved in the log file, and I would like to view the error in a specific view. I was able to log errors into a specific .log file, so the real question is, how can I view errors from another log file?

Yii::trace('db error');

Yii::trace('start calculating average revenue', __METHOD__);

Yii::trace('start calculating average revenue', 'abc');
