How to configure tomcat to rollover catalina.log files

Question

I\'m trying to configure my tomcat to rollover log files once a size limit is reached. I\'m running tomcat as a windows service and am redirecting all my stdout to catalina.

org.apache.juli.FileHandler does not support rotation based on file size and does not have the limit and count properties you are trying to set (see docs). Instead, you can use the standard Java java.util.logging.FileHandler which supports size-based rotation. You should change the following lines in your configuration:

handlers = 1catalina.java.util.logging.FileHandler, 2localhost.org.apache.juli.FileHandler, 3manager.org.apache.juli.FileHandler, 4host-manager.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

.handlers = 1catalina.java.util.logging.FileHandler, java.util.logging.ConsoleHandler

Also note that Java FileHandler is configured slightly differently than Tomcat FileHandler

1catalina.java.util.logging.FileHandler.level = FINEST
1catalina.java.util.logging.FileHandler.pattern = /catalina%g.log
1catalina.java.util.logging.FileHandler.limit = 100000
1catalina.java.util.logging.FileHandler.count = 5
1catalina.java.util.logging.FileHandler.formatter = java.util.logging.SimpleFormatter

However, I'm not sure that redirecting standard out to the file written by the logger will work well and help you achieve what you want.
