I want to display the file Name in the log statement

For every logger statement with any level, I need to display the file name from where the log statement executed, below is the illustration I given below:

Example : Below is the line executed from JobWork.js

logger.info("getInCompleteJobs in job works");

Actual :

2012-11-05T06:07:19.158Z - info: getInCompleteJobs in job works

Required :

2012-11-05T06:07:19.158Z - info JobWork.js : getInCompleteJobs in job works

Without passing the fileName as a parameter from the log statement it should give the filename.

You can use the stack trace information attached to v8's Error object to find out what file/line your code was called from. This approach works well, but it does not perform well; so you will want to disable it in production.

So you could do something like this:

  var logger_info_old = logger.info;
  logger.info = function(msg) {
    var fileAndLine = traceCaller(1);
    return logger_info_old.call(this, fileAndLine + ":" + msg);
  }

  /**
  * examines the call stack and returns a string indicating 
  * the file and line number of the n'th previous ancestor call.
  * this works in chrome, and should work in nodejs as well.  
  *
  * @param n : int (default: n=1) - the number of calls to trace up the
  *   stack from the current call.  `n=0` gives you your current file/line.
  *  `n=1` gives the file/line that called you.
  */
  function traceCaller(n) {
    if (isNaN(n) || n<0) n=1;
    n+=1;
    var s = (new Error()).stack,
        a = s.indexOf('\n', 5);
    while (n--) {
      a = s.indexOf('\n', a+1);
      if (a<0) { 
        a = s.lastIndexOf('\n', s.length);
        break;
      }
    }
    var b = s.indexOf('\n', a+1); 
    if( b<0 ) b = s.length;
    a = Math.max(
      s.lastIndexOf(' ', b),
      s.lastIndexOf('/', b));
    b = s.lastIndexOf(':', b);
    s = s.substring(a+1, b);
    return s;
  }
