We have unit tests that do this. Basically you need to do:
final LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
final Configuration config = ctx.getConfiguration();
Map<String, LoggerConfig> loggers = config.getLoggers();
for (Map.Entry<String, LoggerConfig> logger : loggers.entrySet()) {
logger.setLevel(Level.DEBUG);
}
ctx.updateLoggers();
If you only want to update the root logger than do:
LoggerConfig rootLogger = config.getRootLogger();
rootLogger.setLevel(Level.DEBUG);
instead of the for loop.
