Loggers have a Level property that they use to filter logging events
before they route the event to the appender. The Level is inherited from
their parent Logger unless specified.
You don't want to set the Threshold on the appender unless you never
want to see events below that threshold in the output.
Try this:
static void Main(string[] args)
{
Logger a = LogManager.GetLogger("a").Logger as Logger;
Logger ab = LogManager.GetLogger("a.b").Logger as Logger;
Logger ac = LogManager.GetLogger("a.c").Logger as Logger;
ConsoleAppender ca = new ConsoleAppender();
ca.Name = "Test";
ca.Layout = new SimpleLayout();
ca.ActivateOptions();
a.AddAppender(ca);
a.Repository.Configured = true;
// Set level on logger 'a'. This will be inherited by other loggers
a.Level = Level.ERROR;
// Override the level on 'a.b'. Set it to Debug
ab.Level = Level.DEBUG;
ILog abLog = LogManager.GetLogger("a.b");
abLog.Debug("Test Error message for ab");
ILog acLog = LogManager.GetLogger("a.c");
acLog.Warn("Test Error message for ac");
}
