Hello,
Thank you for your replies. Don't get me wrong. The markers and marker
filters themselves work. However, my point was that the method
Logger#isEnabled(Level level, Marker marker) only checks if the logger is
enabled for the level and not the marker.
Minimal example:
package com.ezakus.log;
import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.apache.logging.log4j.Marker;
import org.apache.logging.log4j.MarkerManager;
public class LoggerWithMarkerTest {
private static Logger logger =
LogManager.getLogger(LoggerWithMarkerTest.class.getName());
private static final Marker markerOne =
MarkerManager.getMarker("marker_one");
public static void main(String[] args) {
if (logger.isInfoEnabled(markerOne)) {
System.out.println("Activated!");
logger.info(markerOne, "We are logging!");
}
}
}
with configuration:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="DEBUG" monitorInterval="10">
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<!-- <MarkerFilter marker="marker_one" onMatch="DENY"
onMismatch="NEUTRAL"/> -->
<PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} -
%marker - %msg%n"/>
</Console>
</Appenders>
<Loggers>
<Root level="info">
<AppenderRef ref="Console"/>
</Root>
<Logger name="com.ezakus.log.LoggerWithMarkerTest" level="info"
additivity="false">
<MarkerFilter marker="marker_one" onMatch="DENY"
onMismatch="NEUTRAL"/>
<AppenderRef ref="Console"/>
</Logger>
</Loggers>
</Configuration>
The behaviour I expect with that configuration is that the condition in the
code evaluates to false. However, it only ever evalu
