OpenTelemetry Operations Exporters for JavaScript

OpenTelemetry Google Cloud Trace Exporter

OpenTelemetry Google Cloud Trace Exporter allows the user to send collected traces to Google Cloud.

Google Cloud Trace is a distributed tracing system. It helps gather timing data needed to troubleshoot latency problems in microservice architectures. It manages both the collection and lookup of this data.

Getting Started

This exporter package assumes your application is already instrumented with the OpenTelemetry SDK. Once you are ready to export OpenTelemetry data, you can add this exporter to your application:

npm install --save @google-cloud/opentelemetry-cloud-trace-exporter

Add the exporter to your existing OpenTelemetry tracer provider (NodeTracerProvider / BasicTracerProvider)

const { TraceExporter } = require('@google-cloud/opentelemetry-cloud-trace-exporter');
const { NodeTracerProvider } = require('@opentelemetry/node');
const { BatchSpanProcessor } = require('@opentelemetry/tracing');


// Enable OpenTelemetry exporters to export traces to Google Cloud Trace.
// Exporters use Application Default Credentials (ADCs) to authenticate.
// See https://developers.google.com/identity/protocols/application-default-credentials
// for more details.
// Expects ADCs to be provided through the environment as ${GOOGLE_APPLICATION_CREDENTIALS}
const projectId = process.env.GOOGLE_PROJECT_ID;

// Use your existing provider
const provider = new NodeTracerProvider();
provider.register();

// Initialize the exporter
const exporter = new TraceExporter({projectId: projectId});

// Add the exporter to the provider
provider.addSpanProcessor(new BatchSpanProcessor(exporter));
