Hi -
I wanted to share our experience in setting up proper log rotation. As it is out of the box, Pentaho doesn't seem to do much log rotation - Catalina.out grows endlessly, and many other logs while they rotate they don't stop adding new ones.
To fix this, we made the following changes:
1) Create a file called tomcat, which you will place in /etc/logrotate.d/ on linux.
2) Change tomcat/conf/logging.properties to the following, which uses java.util.logging.FileHandler, keeps last 5 files, and keeps up to 20mb in each file. Also changing level to warning drastically reduces the size of these logs.
3) Change the pentaho.log settings in log4j.xml, found in tomcat/webapps/pentaho/WEB-INF/classes, as follows, which keeps 5 files around of 20mb in size. I think you need to download the apache log4j extras file to make this work and drop in the jar directory.
Hope this helps someone, and I welcome any suggestions for improvement to the above. You can also disable audit logging if you don't need it.

Code:
# logrotate config file to rotate out the catalina.out for Tomcat file,
# which will grow too large otherwise. This rotates daily, compressing
# the result, and keeping 7 days worth of logs.
