I would like to configure Grouper so that the old logs are compressed automatically.
I downloaded the apache-log4j-extras-1.2.17.jar file and installed it in GROUPER_HOME/lib/custom and in the WEB-INF/lib directories. I modified the log4j properties to include these directives:

log4j.appender.grouper_error=org.apache.log4j.rolling.RollingFileAppender
log4j.appender.grouper_error.rollingPolicy.maxIndex=7
log4j.appender.grouper_error.triggeringPolicy=org.apache.log4j.rolling.SizeBasedTriggeringPolicy
log4j.appender.grouper_error.triggeringPolicy.MaxFileSize=1024
log4j.appender.grouper_error.rollingPolicy.FileNamePattern=/var/log/tcat/grouperqat/grouper_error.log.%i.gz
log4j.appender.grouper_error.rollingPolicy.ActiveFileName=/var/log/tcat/grouperqat/grouper_error.log
log4j.appender.grouper_error.layout=org.apache.log4j.PatternLayout
log4j.appender.grouper_error.layout.ConversionPattern=%d [%t] %-5p (%F:%L) - %m%n

I get these errors when I start the Grouper shell:

log4j:WARN Please set a rolling policy for the RollingFileAppender named 'grouper_error'
log4j:ERROR No output stream or file set for the appender named [grouper_error].
Grouper starting up: version: 2.3.0, build date: null, env: dev
grouper.properties read from: /var/tomcat/grouperqat/webapps/grouper/WEB-INF/classes/grouper.properties
Grouper current directory is: /opt/apache-tomcat-7.0.82
log4j.properties read from:   /var/tomcat/grouperqat/webapps/grouper/WEB-INF/classes/log4j.properties
Grouper error, file appender path is empty, maybe dir doesnt exist
Grouper is logging to file:   at min level WARN for package: edu.internet2.middleware.grouper, based on log4j.properties

It seems to want TimeBasedRollingPolicy:
log4j.appender.file.RollingPolicy=org.apache.log4j.rolling.TimeBasedRollingPolicy

but when I use that policy the file name must contain the date. I don't want the date to be part of the log file name since I am using a size based triggering policy. Any insight would be appreciated.

Ben
