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?


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());
        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 ?


<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} -

    <level value="off" />
    <appender-ref ref="STDOUT" />
