Reports measured metrics to elasticsearch in the same format as the Java elasticsearch metric reporter.

npm install measured elasticsearch measured-elasticsearch

var elasticsearch = require('elasticsearch');
var client        = new elasticsearch.Client({ host : 'localhost:9200' });

var reporter   = require('measured-elasticsearch').forClient(client);
var measured   = require('measured');
var collection = measured.createCollection();

reporter.addCollection(collection);
reporter.start(60, measured.units.SECONDS);

• forClient(client[, config]) creates a new reporter for the given client and optional config. Available configs are:
  • index the index to use. Defaults to metrics.
  • indexDateFormat the date format to make sure to rotate to a new index. Defaults to yyyy.mm. Uses dateformat.
  • timestampFieldname the field name of the timestamp. Defaults to @timestamp.
  • getTime a function returning the current time. The return value is passed to new Date(time). Default to Date.now().
  • additionalFields object with additional fields to be included for each metric
  • pingTimeout number of millis before the initial ping HEAD request times out. The default is the elasticsearch client default (currently 100).
• sendBulk() sends a bulk update using the elasticsearch client
• start([interval[, unit]]) performs a ping request and once successful sends bulk updates every interval * unit where interval defaults to 60 and unit defaults to 1000.
• stop() stops performing ping and bulk update requests and calls end() on all registered collections

The reporter instance returned by forClient is an EventEmitter that emits these events:

• start when start() was called and the initial ping request was successful
• stop when stop() was called
• update after a bulk update was sent to elasticsearch
• error if the initial ping requests fail and if bulk updates fail
