tomcat logs maintenance

i have configured an application running on tomcat with log4j.
Application works fine.
apart from the logs mentioned in webapp/my-application/WEB-INF/classes/log4j.properties file are there any other logs that get generated?

Specifically am looking for "how to maintain Tomcat Logs" .

I could see currrent logs being refreshed at every 1 hr.which i have not configured in tomcat.Am running only one instance of tomcat

Any ideas about different logs and tips for maintenance would be great.There is no such thing as tomcat administrative guide as far as i know.

Thanks in advance

Welcome to JavaRanch!

We're pleased to have you here with us in the Tomcat forum, but there are a few rules that need to be followed, and one is that proper names are required. Please take a look at the JavaRanch Naming Policy and adjust your display name to match it.

In particular, your display name must be a first and a last name separated by a space character, and must not be obviously fictitious.
The first name can be an initial but not the last.

You can change it here

See:
http://tomcat.apache.org/tomcat-5.5-doc/logging.html

Thanks Ben ,
i could see now all my logs from application are going to Log4j.
