1. Define a Marker
public static final Marker EXCEPTION_MESSAGE =
MarkerManager.getMarker(“EXCEPTION_MESSAGE”);
2. Use the Marker
logger.info(EXCEPTION_MESSAGE, execution);
3. Use the MarkerPatternSelector
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout>
<MarkerPatternSelector defaultPattern="[%-5level] %msg%n">
<PatternMatch key=“EXCEPTION_MESSAGE" pattern="[%-5level] - %msg
%throwable{short.message}%n"/>
</MarkerPatternSelector>
</PatternLayout>
</Console>
