As you read these questions, please keep in mind that Tomcat's internal logging is separate from your own webapp's logging. You would typically be concerned only with your own webapp's logging. You would modify Tomcat's internal logging settings if you are debugging a possible issue or running into other problems. It is anticipated that Tomcat's out-of-the-box logging configuration will be fine for the vast majority of users and environments.
