Instrument Go apps using our Go client library for SignalFx. to send custom metrics from your code. Adding it to your project is as simple as:

import ""

To send an ad-hoc datapoint to SignalFx, use HTTPDatapointSink, the core of the library. Here’s an example:

func SendHelloWorld() {

     client := NewHTTPDatapointSink()

     client.AuthToken = "ABCDXYZ"

     ctx := context.Background()

     client.AddDatapoints(ctx, []*datapoint.Datapoint{

         GaugeF("", nil, 1.0),

You can also easily to send metrics and dimensions on a periodic basis on an interval you define using the built-in scheduler. Read more about our Go client library on

Go is just the latest SignalFx client library, adding to our support for Java, Python, Ruby and node.js.
