yii 1.X application log issue

i have application that is hosted on Amazon EC2 instances
i log my application using Yii 1.X Logger like this

Yii::log("Something i Log Here...", "info");

aaand , as we all know , i log my files into
WEBROOT/protected/runtime/application.log file.
Because of many logs i use, application.log file fill so quick , and , as i see , Yii or server change that file to application.log.1 and creates a new file called application.log .

My Question is , why, when new application.log file is created , Owner and Group are like some user nobody, and , when the new file is created, my code such as logging doesn't work anymore , no good permissions for writing into file as www-data user. Are there any chances to create new application.log file as user different as NOBODY?

I will provide Image , and look closer to application.log.3
ownership, same is happening with application.log , but i've changed
the permissions by command

Anyone Please Help me about this.
