{code}
LoggerContext ctx = (LoggerContext) LogManager.getContext(false);
Configuration config = ctx.getConfiguration();
Map<String, LoggerConfig> loggers = config.getLoggers();
Map<String, Level> priorLevel = new HashMap<String, Level>():
for (Map.Entry<String, LoggerConfig> entry : loggers.entrySet()) {
    priorLevel.put(entry.getKey(), entry.getValue().getLevel());
    entry.getValue().setLevel(newLevel):
}
ctx.updateLoggers();
{code}

when you want to restore the levels:

{code}
for (Map.Entry<String, LoggerConfig> entry : loggers.entrySet()) {
    Level level = priorLevel.get(entry.getKey);
    if (level != null) {
        entry.getValue().setLevel(level):
    }
    ctx.updateLoggers();
}
{code}

>          Issue Type: Question
>          Components: API, Core

>         Environment: win 7 64x
> java 1.7

> Hi everyone,
> There's a need to increase the log level for EVERY logger at runtime and after certain processing, bring it back to the original level.
> I've tried to set the level of ROOT logger use log4j.core.Logger.setLevel, but the level only works on the root logger. I've done some investigation and find setLevel doesn't change the LoggerConfig object, just change the level related to current logger, so loggers share the same LoggerConfig won't change the logger level.
> Is there any way to meet my requirement? I think this is a common one when we have batch work in the application.
> Thanks in advance!
