Hi all,
Our application makes an intensive use of Profiler
(http://www.slf4j.org/extensions.html#profiler).
It has been very useful during the development stage an we would like to
keep it at production stage but there is a problem since its "log level"
is hard-coded to "debug".
Currently the profiler use the same application class logger so if log
level is set to "info" in our production environment we lose the
"profiler" log :-(
Alternatives:
* Use different loggers for application and profiler >-->> It requires
to refactoring all the code and remember that any new Profiler that
will be used need to set a custom logger instead of the default
class logger.
* Open a request to modify Profiler in order to set a custom log level.
This makes sense. See first if the TurboFilter described below
approach works for you. Otherwise, please file a bug report requesting
for this feature.
* Keep minimum log level to "debug" and make use of a Filter to accept
any log event with marker=PROFILER, otherwise only accept if log
level >= INFO >-->> It only will work with LogBack but Profiler
belongs to SLF4J so it should work with any bridge.
Have you considered using a TurboFilter [1]? Here is a TurboFilter
which will enable profiler logs for all logging levels.
import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.Logger;
import ch.qos.logback.classic.turbo.TurboFilter;
import ch.qos.logback.core.spi.FilterReply;
import org.slf4j.Marker;
import org.slf4j.MarkerFactory;
public class ProfilingEnabler extends TurboFilter {
Marker profilerMarker =
MarkerFactory.getMarker(Profiler.PROFILER_MARKER_NAME);
@Override
public FilterReply decide(Marker marker, Logger logger, Level level,
String format, Object[] params, Throwable t){
if(marker == profilerMarker) return FilterReply.ACCEPT;
else return FilterReply.NEUTRAL;
}
}
