Eclipse

1. highlight warning log message in eclipse console:

Configure two separate appenders. One for the levels WARN and higher and one for the levels INFO and lower. Assign them to the std.err and std.out.

Here a config example:

 

    <appender name="CONSOLE.ERR" class="org.apache.log4j.ConsoleAppender">

        <param name="target" value="System.err"/>

        <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="warn"/>

            <param name="LevelMax" value="fatal"/>

            <param name="AcceptOnMatch" value="false"/>

        </filter>

    </appender>

 

    <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="debug"/>

            <param name="LevelMax" value="info"/>

            <param name="AcceptOnMatch" value="false"/>

        </filter>

    </appender>

 

Eclipse console will display WARN and higher in red, INFO and lower in black color.
