Andrew Herr created LOG4J2-865:
----------------------------------

             Summary: Changing level in LoggerConfig does not change AppenderControl  and does not allow messages at new log level to be logged
                 Key: LOG4J2-865
                 URL: https://issues.apache.org/jira/browse/LOG4J2-865
             Project: Log4j 2
          Issue Type: Bug
          Components: Appenders, Configurators
    Affects Versions: 2.0.2
         Environment: Windows7 64bit, Eclipse, Maven
            Reporter: Andrew Herr
             Fix For: 2.0.2


I am wrapping log4j2 in order to replace the logging backend used in house, so I am configuring the logger and appenders at runtime with calls to the Context, Configuration, and LoggerConfig. I'd like to change the log level on the fly, so I get the LoggerConfig for my named logger and call setLevel(Level) on it, and then updateLoggers in the context. New messages at the new (less severe) level are not logged. Through a debug session, I can see that the level in LoggerConfig is correctly updated, but the AppenderControl still has the old level, so callAppenders denies my event from being logged.

Code:
Set up the logger + RollingFileAppender
        name = logName;
        level = logLevel;
        LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
        Configuration config = ctx.getConfiguration();
        
        LoggerConfig loggerConfig = new LoggerConfig(name, level, false);
        PatternLayout layout = PatternLayout.createLayout(PatternLayout.SIMPLE_CONVERSION_PATTERN, config, null, null, true, false, null, null);
        
        OnStartupTriggeringPolicy startupTrigger = OnStartupTriggeringPolicy.createPolicy();
        SizeBasedTriggeringPolicy sizeTrigger = SizeBasedTriggeringPolicy.createPolicy("25MB");
        TriggeringPolicy triggerPolicy = CompositeTriggeringPolicy.createPolicy(startupTrigger, sizeTrigger);
        DefaultRolloverStrategy rolloverStrategy = DefaultRolloverStrategy.createStrategy("5", "1", "min", null, config);
        RollingFileAppender rollingFileAppender = RollingFileAppender.createAppender(name + ".log", name + ".log.%i", "true", "RollingFile",
                "true", "8192", "true", triggerPolicy, rolloverStrategy, layout, null, "true", "false", null, config);
        rollingFileAppender.start();
        loggerConfig.addAppender(rollingFileAppender, level, null);
        config.addLogger(name, loggerConfig);
        ctx.updateLoggers();


update the level:
        LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
        Configuration config = ctx.getConfiguration();
        LoggerConfig loggerConfig = config.getLoggerConfig(name);
        loggerConfig.setLevel(logLevel);
        ctx.updateLoggers();
