A Node.js module for interacting with a local Datadog StatsD agent over UDP.
Datadog extends StatsD with additional features — histograms and tags. This client is an extension of a general StatsD client to work with their implementation.
npm install @grove/dogstatsd
const DogStatsD = require('@grove/dogstatsd')
const metrics = new DogStatsD()
metrics.increment('active_users')
Note: If you want to use this library as a generic StatsD client it will work just fine. Just don't pass in tags
parameters or use the histogram
method.
See the Datadog DogStatsD guide for information on using these methods.
Aside from the constructor and sendEvent
, the options
parameter is a hash that may include tags
and sampleRate
If a socket
parameter is not provided a UDP socket is created and cleaned up as needed.
The last parameter is an optional options
object, which may have the following properties:
globalTags
: an array of strings to be included as tags with every metric sent
If you're passing options
you must also pass delta
options
is a hash that may include tags
and sampleRate
If you're passing options
you must also pass delta
Returns an object with a stop
method to call. Then calls timing
under the hood with the measured change in time. Uses process.hrtime
for high-resolution timing.
Options include:
dateHappened=Date.now()
priority='normal'
type='info'
hostname
aggregationKey
sourceTypeName
tags
If no socket
argument is given to the constructor, then a UDP socket is created as needed when sending data to the Datadog agent. We place a no-op function as the error handler to swallow any errors that may occur on the socket.
If a socket
argument is given, then it's up to the user to provide error handling mechanisms. A client's socket is accessible from the client.socket
property.
