Hi, I am preparing something like web interface for my app logging configuration, similar to yours JMX configurator. As I noticed when you add new logger in the runtime then it is impossible to remove it (set its log level null). I have checked the shutdownAndReset() and id doesn't work. I have attached the source code which should explain you what I would like achieved. Could you check it? Thanks, -mateusz package foo; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import ch.qos.logback.classic.Level; import ch.qos.logback.classic.LoggerContext; import ch.qos.logback.classic.jmx.Configurator; public class Main { private static final Logger LOGGER = LoggerFactory.getLogger(Main.class); public static void main(String[] args) { LOGGER.info("Message #1"); //shouldn't be logged, LOGGER's level is null so takes root's off level LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory(); ch.qos.logback.classic.Logger log = lc.getLogger(LOGGER.getName()); log.setLevel(Level.INFO); LOGGER.info("Message #2"); //should be logged, LOGGER's level is info Configurator config = new Configurator(lc); config.reload(); //shutdownAndReset() is call inside this method LOGGER.info("Message #3"); // why it is logged here ? LOGGER's level is still INFO, shouldn't be null ? } } logback.xml: <configuration> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <layout class="ch.qos.logback.classic.PatternLayout"> <Pattern>%d{HH:mm:ss.SSS} [%thread] %5level %logger{18} - %msg%n</Pattern> </layout> </appender> <root> <level value="off" /> <appender-ref ref="STDOUT" /> </root> </configuration>
