Hi, here is the exact configuration I'm using now.

<?xml version="1.0" encoding="UTF-8"?>

<configuration>

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <layout class="ch.qos.logback.classic.PatternLayout">
      <param name="pattern" value="%-4relative [%thread] %-5level %class - %msg%n" />
    </layout>
</appender>

<appender name="bitranlog" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <param name="File" value="bitran.log" />
    <rollingPolicy class="ch.qos.logback.core.rolling.SizeBasedRollingPolicy">
       <param name="MaxFileSize" value="5MB" />
    </rollingPolicy>
    <layout class="ch.qos.logback.classic.PatternLayout">
      <param name="pattern" value="%-4relative [%thread] %-5level %class - %msg%n" />
    </layout>
</appender>

<logger name="org.accma.concentrator.services.bitran.BiTranService">
    <level value="debug"/>
    <appender-ref ref="bitranlog"/>
</logger>

<root>
    <level value="debug" />
    <appender-ref ref="STDOUT" />
</root>

</configuration>

Hello Samuel,

Thanks for trying logback!

The RollingFileAppender needs a TriggeringPolicy object to know when to roll the
active output file.
In brief, a TriggeringPolicy controls the conditions under which roll-over occurs.
Such conditions include time of day, file size, an external event, the log request or
a combination thereof.

A working configuration file for a RollingFileAppender would be:

With this configuration, the file would be rolled each time it reaches 5MB.

When I look at the configuration file that you sent, something seems strange to me:
Why do you configure two Loggers with the same Appender and one of them with the
Additivity flag set to false? One would obtain the same result simply by attaching
the RollingFileAppender to the root logger.

Hope this helps you get on track with logback. Do not hesitate to write again if you
run into trouble.

Sébastien
