How to better configure log rotation in Alfresco?

brgsousa — Mon, 30 Sep 2013 20:51:10 GMT

I have a big problem with files generated in alfresco (alfresco.log, share.log and solr.log) and tomcat (tomcat/logs/*). They seem to grow and rotate indefinitely and I don't know where rotation parameters are configured. I wish to use system's logrotate (example: /etc/logrotate.d/alfresco) but I th

Hi,
since Alfresco uses log4j for logging, you have some choices.
This solution gives you the opportunity to limit the file size and to decide the number of backup files.


log4j.appender.R.MaxFileSize=100KB
# Keep one backup file

log4j.appender.R.MaxBackupIndex=1
‍‍‍‍‍‍

Personally I prefer the DailyRollingFileAppender that rolls each day on a new file


# LOG4J daily rolling log files configuration
log4j.rootLogger=DEBUG, RollingAppender

log4j.appender.RollingAppender=org.apache.log4j.DailyRollingFileAppender

log4j.appender.RollingAppender.File=app.log
 
log4j.appender.RollingAppender.DatePattern='.'yyyy-MM-dd

log4j.appender.RollingAppender.layout=org.apache.log4j.PatternLayout

log4j.appender.RollingAppender.layout.ConversionPattern=[%p] %d %c %M - %m%n
‍‍‍‍‍‍‍‍‍‍‍‍‍‍

You can chack log4j page for more info at http://logging.apache.org/
If you need to modify Tomcat's log you need to refer to Tomcat Juli, which performs all logging operations.

Thanks for the information, but which of the 4 log4j.properties files is the most important one to update?

I've updated:
./tomcat/webapps/share/WEB-INF/classes/log4j.properties
./tomcat/webapps/alfresco/WEB-INF/classes/log4j.properties
./solr4/log4j-solr.properties

With:

log4j.appender.File.MaxFileSize=1000KB
log4j.appender.File.MaxBackupIndex=5

Is that sufficient to stop the infinitely growing log files I have?
