Hi,

I have created following appender in logback.xml file. The log files are getting created but the logs are not rolling over. It is on 2012 server with tomcat.

<appender name="DEFAULT_APPENDER" class="ch.qos.logback.core.rolling.RollingFileAppender">

<file>${APP_HOME}/logs/App.log</file>
<encoder>
<pattern>%-5level %d

{MM/dd HH:mm:ss.SSS}

[%thread] %logger

{20}

%msg%n</pattern>
</encoder>

<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">
<fileNamePattern>${APP_HOME}/logs/App.log.%i</fileNamePattern>
<minIndex>1</minIndex>
<maxIndex>5</maxIndex>
</rollingPolicy>

<triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">
<maxFileSize>5MB</maxFileSize>
</triggeringPolicy>

But with below option ,

<fileNamePattern> ${APP_HOME}/logs/App.log.%i.zip </fileNamePattern>

With zip option for rolling the there are 5 log zip files are created but all of them has same data. The actual log is growing.

Please let me know what may be the issue.

Thanks
Sasi
