A Bunyan stream for saving logs into Elasticsearch.

Logstash Template
By default Logstash will create a dynamic template that will take care of crating .raw
fields for your data. In order to replicate this behavior 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
Example
var bunyan = require('bunyan');
var Elasticsearch = require('bunyan-elasticsearch');
var esStream = new Elasticsearch({
indexPattern: '[logstash-]YYYY.MM.DD',
type: 'logs',
host: 'localhost:9200'
});
esStream.on('error', function (err) {
console.log('Elasticsearch Stream Error:', err.stack);
});
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'));
