Hi Dario, There is a bug in org.slf4j.ext.LoggerWrapper which LogLogger extends. The methods taking a Marker as first argument, invoke isInfoEnabled() instead of inInfoEnabled(marker). For example, the code currently reads: public void info(Marker marker, String msg) { if (!logger.isInfoEnabled()) return; if (instanceofLAL) { ((LocationAwareLogger) logger).log(marker, fqcn, LocationAwareLogger.INFO_INT, msg, null, null); } else { logger.info(marker, msg); } } instead of public void info(Marker marker, String msg) { if (!logger.isInfoEnabled(marker)) return; if (instanceofLAL) { ((LocationAwareLogger) logger).log(marker, fqcn, LocationAwareLogger.INFO_INT, msg, null, null); } else { logger.info(marker, msg); } } The Please file bug report so that this issue can be tracked. You can file the bug report in logback or slf4j (the bug is actually in slf4j-ext). Sorry for the inconvenience, -- Ceki http://twitter.com/#!/ceki On 10.06.2012 11:21, Dario Campagna wrote:

Hi Ceki,

...

Could you provide a code sample of how you invoke a LocLogger with a marker?

Sure! The following class shows how I use a LocLogger to generate a logging request with a marker.

public class LocLoggerTest {

public static void main(String[] args) {

IMessageConveyor mc = new MessageConveyor(Locale.getDefault());

LocLoggerFactory llFactory_default = new LocLoggerFactory(mc);

LocLogger locLogger = llFactory_default.getLocLogger("defaultLocLogger");

Marker alwaysMarker = MarkerFactory.getMarker("ALWAYS");

locLogger.info(alwaysMarker,"This will always appear.");

locLogger.info("Hello!");

}

}

A simple configuration file to test it is

<configuration debug="true">

<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%level - %date - %marker - %msg%n</pattern> </encoder> </appender>

<turboFilter class="ch.qos.logback.classic.turbo.MarkerFilter"> <Marker>ALWAYS</Marker> <OnMatch>ACCEPT</OnMatch> <OnMismatch>NEUTRAL</OnMismatch> </turboFilter>

<logger name="defaultLocLogger" level="INFO"> <appender-ref ref="STDOUT" /> </logger>

</configuration>

When I change the logger level to a value grater than INFO, the logging request marked ALWAYS is not enabled.

Cheers, Dario
