## Adding the bunyan-logstash stream to Bunyan

```
var log = bunyan.createLogger({
  streams: [
    {
      type: "raw",
      stream: require('bunyan-logstash-tcp').createStream({
        host: '127.0.0.1',
        port: 9908
      })
    }
  ]
});
```

## Example

```javascript
"use strict";

var bunyan = require('bunyan'),
    bunyantcp = require('bunyan-logstash-tcp');

var log = bunyan.createLogger({
    name: 'example',
    streams: [{
        level: 'debug',
        stream: process.stdout
    },{
        level: 'debug',
        type: "raw",
        stream: bunyantcp.createStream({
            host: '127.0.0.1',
            port: 9998
        })
    }],
    level: 'debug'
});

log.debug('test');
log.error('error test');
```

## Logstash Configuration

Configuration for [Logstash 1.3.3+](http://logstash.net/docs/1.4.2/inputs/tcp):

```javascript
input {
  // config for bunyan udp
  udp {
      'port' => "9999"
  }
  // config for bunyan tcp
  tcp {
      'port' => "9998"
  }
}
```

## Try with logstash locally

 - Download logstash from http://logstash.net/
 - Unpack it (tar -zxf logstash-1.4.2.tar.gz)
 - Create a test logstash configuration `logstash.conf`

```code
input {
  stdin { 
    type => "stdin-type"
  }
  udp {
    port => "9999"
  }
  tcp {
    port => "9998"
  }
}
output { 
  stdout {}
}
```

 - Run `bin/logstash agent -f logstash.conf
 - Run `node example/log.js`
