Rather than developing a Go specific OpenTelemetry exporter New Relic is now offering native OTLP ingest.

The current recommended approaches for sending OpenTelemetry data to the New Relic platform are as follows:

• Configure your OpenTelemetry data source to send data to the OpenTelemetry Collector using the OpenTelemetry Protocol (OTLP) and configure the collector to forward the data using the New Relic collector exporter.
• Configure your OpenTelemetry data source to send data to the native OpenTelemetry Protocol (OTLP) data ingestion endpoint. OTLP is an open source gRPC based protocol for sending telemetry data. The protocol is vendor agnostic and open source.

• Native OpenTelemetry Protocol (OTLP) support

New Relic Go OpenTelemetry exporter

The "github.com/newrelic/opentelemetry-exporter-go/newrelic" package provides an exporter for sending OpenTelemetry data to New Relic. Currently, traces and the latest metric instruments (as of v0.19 of Open Telemetry for Go) are supported.

Getting Started

Go OpenTelemetry

OpenTelemetry is a set of vendor-neutral tools, APIs, SDKs, and an optional collector service for capturing distributed traces and metrics from your application. New Relic’s Go OpenTelemetry Exporter makes it easy for you to export your captured data to your New Relic account.

To help you get started, this guide shows you how to set up a tiny Go application to send spans and metrics to New Relic. If you have an application that already uses an existing framework like gin or beego, it’s worth your time to go through the steps below, and then check out the many auto-instrumentation options in the opentelemetry-go-contrib repository.

Get Started

Here’s what you need to get started exporting OpenTelemetry spans and metrics to New Relic:

• Make sure you have signed up for a New Relic account.
• Obtain an Insights Event Insert API Key to send spans and metrics to New Relic. (In that guide, you only need to proceed as far as obtaining a new key, the rest of the steps are optional.)

At this point, you have a couple of alternatives:

• If you just want to see it working quickly, we have a tiny sample application set up for you right here, already set up to export data to your New Relic account. Once you have it checked out, skip to Running the sample application in this document.
• If you’re starting from scratch, review the Go OpenTelemetry Getting Started Guide. This excellent guide will walk you through creating a tiny sample application that generates spans and metrics, and outputs text to your terminal. Then modify your sample application to send data to New Relic using the instructions below.

Lastly, view your data in the New Relic One UI. Very satisfying!

Modify the OpenTelemetry sample application

Here’s what to do to switch out the text-based exporter defined in the Go OpenTelemetry SIG’s Getting Started Guide with the New Relic OpenTelemetry Exporter for Go.

There are three steps to get it reporting to New Relic:

1. replace an import statement, and add some imports
2. instantiate a newrelic exporter with some configuration options
3. set the span.kind for a better UI experience in New Relic

Full source of this modified sample application is available in examples/simple/main.go.

1. Replace the exporter import clause. Switch this:

   "go.opentelemetry.io/otel/exporters/stdout"
   

   ...with this:

   "github.com/newrelic/opentelemetry-exporter-go/newrelic"
   

   You'll also need to add some imports, if they're missing:

   "os"
   "fmt"
   "github.com/newrelic/newrelic-telemetry-sdk-go/telemetry"
   

2. Rather than instantiate a stdout exporter, instantiate a newrelic exporter. Replace this:

    exporter, err := stdout.NewExporter(
        stdout.WithPrettyPrint(),
    )
    if err != nil {
        log.Fatalf("failed to initialize stdout export pipeline: %v", err)
    }
    ctx := context.Background()
   

   ...with this:

    apiKey, ok := os.LookupEnv("NEW_RELIC_API_KEY")
    if !ok {
    	fmt.Println("Missing NEW_RELIC_API_KEY required for New Relic OpenTelemetry Exporter")
    	os.Exit(1)
    }
   
    exporter, err := newrelic.NewExporter(
    	"Simple OpenTelemetry Service",
    	apiKey,
    	telemetry.ConfigBasicErrorLogger(os.Stderr),
    	telemetry.ConfigBasicDebugLogger(os.Stderr),
    	telemetry.ConfigBasicAuditLogger(os.Stderr),
    )
    if err != nil {
    	fmt.Printf("Failed to instantiate New Relic OpenTelemetry exporter: %v\n", err)
    	os.Exit(1)
    }
   
    ctx := context.Background()
    defer exporter.Shutdown(ctx)
   

   There are four things to notice above:

   • The configuration reads the Insights Insert Key you obtained earlier from an environment variable called NEW_RELIC_API_KEY. Keep this key safe from others, since it’s both identification and authentication in one handy token.

   • This exporter uses Simple OpenTelemetry Service as its service name. This is the name you will see in the New Relic One UI.

   • The configuration turns on all the logging it can for the purposes of this demo. To have a more silent exporter with lower overhead, remove those three lines.

   • Once we have the context (ctx), we defer the Shutdown function so the exporter has a chance to flush any accumulated data to the New Relic Metrics and Traces endpoints.

3. This example generates a parent span and a child span. For the parent, set the kind of span to "server" to get the best experience in the New Relic UI.

   Change:

   		ctx, span = tracer.Start(ctx, "operation")
   

   ...to:

   		ctx, span = tracer.Start(ctx, "operation",
   			trace.WithSpanKind(trace.SpanKindServer))
   

You’re now set! If you’re not using go mod, you’ll need to download the exporter using the go get command:

go get github.com/newrelic/opentelemetry-exporter-go

Running the sample application

To see it in action, just use go run with the Insights Insert API Key set in the environment:

NEW_RELIC_API_KEY=NRII-REPLACE_THIS_KEY run main.go

Note that the key above isn’t a valid key -- replace it with your own.

Run that line a couple of times to send some data into New Relic.

View your data in the New Relic One UI

To see span data

Go to the New Relic One UI in your web browser, click the magnifying glass in the upper right corner and type your service name, which is Simple OpenTelemetry Service if you didn't change it from the example. New Relic searches through everything your user has permissions to see and will show you a link to the application. If you’re using a web framework, you’ll see a Summary overview containing response time, throughput, and errors. To see just the spans, click the “Distributed Tracing” header on the left.

To see metric data

Go to the New Relic One UI in your web browser, click the "Query your data" link in the upper right corner, select your account, and then try this query: SELECT * FROM Metric where entity.name like 'Simple OpenTelemetry Service'

For more tips on how to find and query your data in New Relic, see Find trace/span data.

This exporter is built on alpha software

This exporter is built with the alpha release of OpenTelemetry Go client. Due to the rapid development of OpenTelemetry, this exporter does not guarantee compatibility with future releases of the OpenTelemetry APIs. Additionally, this exporter may introduce changes that are not backwards compatible without a major version increment. We will strive to ensure backwards compatibility when a stable version of the OpenTelemetry Go client is released.
