Re: dynamic logging control

Are you looking at the Logger or LoggerConfig.  Log4j 2 separates Loggers from their configuration. 

To modify a logLevel you need to do:

LoggerContext context = (LoggerContext) LogManager.getContext(false);
Configuration config = context.getConfiguration();
LoggerConfig loggerConfig = config.getLoggerConfig(loggerName);
loggerConfig.setLevel(level);
context.updateLoggers();

This process locates the configured Logger for the desired logger name, sets its level and then modifies all the Loggers that use the LoggerConfig.
