In order to print a particular level only you can use LevelFilters which you
can configure in xml configuration. E.g.
<appender name="CONSOLE.OUT" class="org.apache.log4j.ConsoleAppender">
<param name="target" value="System.out"/>
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%d{HH:mm:ss.SSS} (%6r) %-5p
[%-7t] %F:%L %x - %m%n"/>
</layout>
<filter class="org.apache.log4j.varia.LevelRangeFilter">
<param name="LevelMin" value="trace"/>
<param name="LevelMax" value="info"/>
<param name="AcceptOnMatch" value="false"/>
</filter>
</appender>
