No, logback does not offer this functionality although it would be very easy to
write one. Just copy and paste threshhold filter and inverse the comparison logic.
Here it is:
public class InvertedThresholdFilter extends Filter<ILoggingEvent> {
Level thresholdLevel;
@Override
public FilterReply decide(ILoggingEvent event) {
if (!isStarted()) {
return FilterReply.NEUTRAL;
}
int eventLevelInt = event.getLevel().toInt();
int thresholdLevelInt = thresholdLevel.toInt();
if (eventLevelInt <= thresholdLevelInt) {
return FilterReply.NEUTRAL;
} else {
return FilterReply.DENY;
}
}
public void setLevel(String level) {
this.thresholdLevel = Level.toLevel(level);
}
public void start() {
if (this.level != null) {
super.start();
}
}
}

Hi,
does logback offer some functionality that can be thought of the
opposite of the ThresholdFilter, i.e. I want an appender to log only
events with levels BELOW and equal to the level specified.
With log4j, there is the org.apache.log4j.varia.LevelRangeFilter
available that can do such things, does something similar exists in
logback?
thanks in advance,
