Description

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." The logger object in JavaScript is an adapter of log4j in the Service Manager server. Logger names and levels follow the rules of log4j.

Example

This example does the following:

  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
log.setLevel(1); //debug
log.setLevel(2); // info
log.setLevel(3); // warn
log.setLevel(4); // error
log.setLevel(5); // fatal
