I'm trying to split logs based on a System property that changes dynamically at runtime.Is the below Discriminator code the way to go?Will this Discriminator get called for every log statement? import ch.qos.logback.classic.spi.ILoggingEvent;import ch.qos.logback.core.sift.AbstractDiscriminator;public class SysPropDiscriminator extends AbstractDiscriminator { private static final String KEY = "PROP"; @Override public String getDiscriminatingValue(ILoggingEvent event) { String propValue = System.getProperty("my.property"); if (propValue == null || propValue.length() == 0) { return "unknown"; } else { return propValue; } } @Override public String getKey() { return KEY; }} -- View this message in context: http://logback.10977.n7.nabble.com/System-property-based-Discriminator-tp147...
