This method retrieves a logger named according to the value of the name parameter. Loggers are normally named entities, using dot-separated names such as "lib.test01.func01."

1. Retrieve a logger with the given name.
2. Set the logger level to trace.
3. Print different level messages.
4. Set the log levels by the code.

var log = getLog('lib.test01.func01');

log.setLevel('trace');

if (log.isTraceEnabled()){

log.trace('trace message');

}

if (log.isDebugEnabled()){

log.debug('debug message');

}

if (log.isInfoEnabled()){

log.info('informatin message');

}

if (log.isWarnEnabled()){

log.warn('warning message');

}

if (log.isErrorEnabled()){

log.error('error message');

}

if (log.isFatalEnabled()){

log.fatal('fatal message');

}

// Set level by code

log.setLevel("trace");

log.setLevel("debug");

log.setLevel("info");

log.setLevel("warn");

log.setLevel("error");

log.setLevel("fatal");

log.setLevel(0); //trace
