This is what I have tried:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration>
<Appenders>
<Console name="Console" target="SYSTEM_OUT">
<PatternLayout pattern="%-5p [%t]: %m%n"/>
</Console>
</Appenders>
<Loggers>
<Logger name="debug" level="debug">
<AppenderRef ref="Console"/>
</Logger>
<Logger name="verbose" level="info">
<AppenderRef ref="Console"/>
</Logger>
<Logger name="normal" level="warn">
<AppenderRef ref="Console"/>
</Logger>
</Loggers>
</Configuration>
Then I call this:
Logger logger = LogManager.getLogger("verbose");
logger.info("Hello World");
But I see duplicated lines in the output.
INFO [main]: Hello World
11:36:18.191 [main] INFO verbose - Hello World
What am I doing wrong?
Thanks,
Arwen

Subject: Set the log level based on command line args
I am investigating migrating from log4j 1 to log4j 2. A pattern that I have in
many of my applications is setting the log level based on command line
arguments. So if the -v (verbose) option is passed I set the log level to
Info. The default is set to warn.
if (line.hasOption("v"))
{
logger.setLevel(Level.INFO);
}
if (line.hasOption("d"))
{
logger.setLevel(Level.DEBUG);
}
In the world of log4j 2, what is the recommended way to accomplish this?
Thanks,
Arwen
