  <appender name="stats" class="org.apache.log4j.FileAppender" >
    <param name="File" value="/tmp/mmbase.stats" />
    <param name="Encoding"   value="UTF-8" />
    <layout class="org.apache.log4j.PatternLayout">
      <param name="ConversionPattern" value="%d{YYYY-MM-dd HH:mm:ss} %c{1} %m%n" />
    </layout>
  </appender>

 <logger name="org.mmbase.STATS" additivity="false">
    <level class="&mmlevel;" value ="service" />
    <appender-ref ref="stats" />
