datadog-statsd-metrics-collector

A wrapper for for node-dogstatsd that buffers and rolls up metrics into efficient calls to a Datadog StatsD server.

Install

npm install datadog-statsd-metrics-collector node-dogstatsd

Usage

const StatsD = require('node-dogstatsd').StatsD
const Collector = require('datadog-statsd-metrics-collector');

const dd = new Collector(new StatsD('example.org', 8125));
dd.increment('test.metric', 1, ['tag:first']);

Buffered stats

• increment
• incrementBy
• decrement
• decrementBy

• histagram

API

Aside from the constructor all StatsD calls proxied to node-dogstatsd.

constructor(client, delayMilliseconds)

arg	type	required	default
client	instanceof node-dogstatsd	yes	undefined
delayMilliseconds	number	no	10000

increment(metrics, sample_rate, tags)

arg	type	required	default
metric	string	yes	undefined
sample_rate	n/a	n/a	n/a
tags	array[string]	no	undefined

Note: sample rates are ignored as they serve no purpose when rolling up metrics.

incrementBy(metrics, value, tags)

arg	type	required	default
metric	string	yes	undefined
value	number	no	1
tags	array[string]	no	undefined

decrement(metrics, sample_rate, tags)

arg	type	required	default
metric	string	yes	undefined
sample_rate	n/a	n/a	n/a
tags	array[string]	no	undefined

Note: sample rates are ignored as they serve no purpose when rolling up metrics.

decrementBy(metrics, value, tags)

arg	type	required	default
