An OpenTelemetry reporter for sending spans to New Relic using the New Relic Java Telemetry SDK. For the juicy details on how OpenTelemetry spans are mapped to New Relic spans, see documentation in Our exporter specifications documentation

To send spans to New Relic, you will need an Insights Insert API Key.

Note: There is an example BasicExample.java
in the test source code hierarchy that matches this example code. It should be considered as the canonical code for this example, since OpenTelemetry internal SDK APIs are still a work in progress.

1. Create a NewRelicSpanExporter

    NewRelicSpanExporter exporter = NewRelicSpanExporter.newBuilder()
        .apiKey(System.getenv("INSIGHTS_INSERT_KEY"))
        .commonAttributes(new Attributes().put("service.name", "best service ever")).build();

2. Build the OpenTelemetry BatchSpansProcessor with the NewRelicSpanExporter

    BatchSpansProcessor spanProcessor = BatchSpansProcessor.newBuilder(exporter).build();

3. Add the span processor to the default TracerSdkFactory

    TracerSdkFactory tracerSdkFactory = (TracerSdkFactory) OpenTelemetry.getTracerFactory();
    tracerSdkFactory.addSpanProcessor(spanProcessor);

4. Create the OpenTelemetry Tracer and use it for recording spans.

    Tracer tracer = OpenTelemetry.getTracerFactory().get("sample-app", "1.0");
    
    Span span = tracer.spanBuilder("testSpan").setSpanKind(Kind.INTERNAL).startSpan();
    try (Scope scope = tracer.withSpan(span)) {
      //do some work
      Thread.sleep(1000);
      span.end();
    }

5. Find your spans in New Relic One: go to https://one.newrelic.com/ and select Distributed Tracing.

build.gradle:

repositories {
    maven {
        url = "https://oss.sonatype.org/content/repositories/snapshots"
    }
}

implementation("com.newrelic.telemetry:opentelemetry-exporters-newrelic:0.2.0-SNAPSHOT")
implementation("io.opentelemetry:opentelemetry-sdk:0.2.0")
implementation("com.newrelic.telemetry:telemetry-core:0.3.2")
implementation("com.newrelic.telemetry:telemetry-http-okhttp:0.3.2")

CI builds are run on Azure Pipelines:

The project uses gradle 5 for building, and the gradle wrapper is provided.

To compile, run the tests and build the jar:

$ ./gradlew build
