A Bunyan stream for saving logs into Elasticsearch.

npm install bunyan-elasticsearch

By default Logstash will create a dynamic template that will take care of crating .raw fields for your data. In order to replicate this behaivor you will need to create the dynamic template manually. You will need to download template.json and run the following command from the same directory as that file:

curl -XPUT localhost:9200/_template/logstash -d @template.json

var bunyan = require('bunyan');
var Elasticsearch = require('bunyan-elasticsearch');
var esStream = new Elasticsearch({
  indexPattern: '[logstash-]YYYY.MM.DD',
  type: 'logs',
  host: 'localhost:9200' 
});

var logger = bunyan.createLogger({
  name: "My Application",
  streams: [
    { stream: process.stdout },
    { stream: esStream }
  ],
  serializers: bunyan.stdSerializers
});

logger.info('Starting application on port %d', app.get('port'));
