Hello Gianni, I have opened a jira issue regarding this problem. Its url is http://jira.qos.ch/browse/LBCLASSIC-105 Looking at the configuration file, the File property reads "${catalina.home}/logs/rp.log" while the FileNamePattern property is set to "rp.%i.log.gz". This means that the archived files will be located in current folder. If you wish to have the archived files located next to the current log file, you need to set FileNamePattern property to "${catalina.home}/logs/rp.%i.log.gz" I have tested your configuration file, and it seems to work just fine. If there are indeed problems with the roll over, they should be visible by printing logback's internal status. Here is code that does that: LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory(); StatusPrinter.print(lc); Invoke it after roll over occurs or at application exit. Gianni Doe wrote:

A bit more information - according to the logs my configuration seems ok, any ideas why the triggering policy is not working?

Hi My log files are not rolling over with the following appender and they grow indefinitely in size:

<appender class="ch.qos.logback.core.rolling.RollingFileAppender" name="R"> <File>${catalina.home}/logs/rp.log</File> <Append>true</Append> <filter class="ch.qos.logback.classic.filter.ThresholdFilter"> <level>debug</level> </filter> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"> <FileNamePattern>rp.%i.log.gz</FileNamePattern> <MinIndex>1</MinIndex> <MaxIndex>3</MaxIndex> </rollingPolicy> <TriggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <MaxFileSize>5MB</MaxFileSize> </TriggeringPolicy> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%-30(%d{HH:mm:ss.SSS} [%thread]) %-5level %logger{64} - %msg %n</Pattern> </layout> </appender>

At some point this appender was working correctly so I'm a bit baffled - any suggestions for debugging why it's not working would be appreciated. Thanks Gianni

PS. Not sure if this is relevant but I've been upgrading logback as new versions have been released but I couldn't say if it stopped working with a particular release or not.
