winston-tcp-graylog

npm i -S winston-tcp-graylog winston

A graylog2 transport for winston based on the node-gelf-pro library. Support TCP and UPD protocol.

Example

import winston from 'winston'
import WinstonTcpGraylog from '../src'

var options = {
  gelfPro: {
    adapterName: 'tcp',
    adapterOptions: {
      host: '127.0.0.1',
      port: 12201
    }
  }
}

var wGraylog = new winston.transports.TcpGraylog(options)
var wConsole = new winston.transports.Console()

var logger = new winston.Logger({
  transports: [ wGraylog, wConsole ]
})

logger
  .on('error', err => {
    // internal winston problems
    console.error('!error: ', err)
  })
  .on('logging', (transport, level, msg, meta) => {
    // each winston transports
    console.info('!logging: ', transport.name, level, msg, meta)
  })

wGraylog
  .on('error', err => {
    // internal WinstonTcpGraylog problems
    console.error('!wtg:error: ', err)
  })
  .on('send', (msg, res) => {
    // only WinstonTcpGraylog "logging"
    console.info('!wtg:send: ', msg, res)
  })
  .on('skip', warn => {
    // only WinstonTcpGraylog "skiping"
    console.warn('!wtg:skip: ', warn)
  })

logger.info('123', { meta: 123, foo: 345, bar: 689 })
logger.warn('%j - %j - %s - %s', [1, 2, 3], { 1: 2 }, /123/, new Error('123'))

What is the `import WinstonTcpGraylog from '../src'` doing? It's never used in the code that follows and it assumes I have a folder `src` somewhere lying around? I tried implementing winston graylog like this and that does not seem to work:
```
var winston = require('winston');
// Only implement the graylog server transport, when the graylog Server IP is set.
var transports = [];
transports.push(new (require('winston-tcp-graylog'))({
name: 'tcpGraylog',
handleExceptions: false,
gelfPro: {
adapterName: 'tcp',
adapterOptions: {
protocol: 'tcp',
host: '93.189.28.58',
port: 12201
}
}
}));
var grayLogger = new winston.Logger({
transports: transports
});
```
I seem to miss something.... Any suggestions? Thanks
