title: Graylog logging in sails using winston-graylog2
body: <p>In my sailsjs Application, I am logging to a file using winston. Logs are getting stored properly in file. I have added a graylog transport but i am unable to get any logs in graylog.
  Following is my code in config/log.js</p>
  
  <pre><code>var logger = new (winston.Logger)({
          transports: [
                       new (winston.transports.Console)( { } ),
                       new (winston.transports.File)({ filename: 'application.log',
                                                       levels  : 'info',
                                                       json    : false,
                                                       colorize: true
                           }),
                       new (WinstonGraylog2)({
                        name            : 'Graylog',
                        level           : 'info',
                        silent          : false,
                        handleExceptions: false,
                        prelog          : function (msg) {
                          return msg.trim();
                        },
                        graylog         : {
                          servers   : [{
                            host: config.graylogHostName,
                            port: config.graylogPort
                          }],
                          facility: config.graylogFacility,
                          bufferSize: 1400
                        }
                       })
                      ]
      });
