[Building Sakai] Awesome log file

[Matthew Jones]

Hi Jon,

By default, sakai doesn't roll the log files daily. You can pretty easily
change the configuration though to do whatever you want. For the quick
rundown look at this SAK:
http://jira.sakaiproject.org/browse/SAK-16426

I'm mostly using the properties file that I have attached. It writes the log
to /var/log/sakai/${serverId}.log and rolls them daily. serverId is passed
as a -D startup parameter to tomcat, so something like:

JAVA_OPTS="$JAVA_OPTS -DserverId=${HOSTNAME}"

But you can just hardcode it if you want to whatever filename. You can
probably also use ${catalina.home}/logs instead of /var/log/sakai.

Just put that file in ${catalina.home}/common/classes/log4j.properties and
it will perform more customized logging. I'll update the confluence
documentation shortly concerning sakai logging with this information. You
can even use other appenders or write and use your own.
