Introduction

Stackdriver Trace is a distributed tracing system that collects latency data from your applications and displays it in the Google Cloud Platform Console.

You can track how requests propagate through your application and receive detailed near real-time performance insights. Stackdriver Trace automatically analyzes all of your application’s traces to generate in-depth latency reports to surface performance degradations, and can capture traces from all of your VMs, containers, or Google App Engine projects.

OpenCensus Node.js has support for this exporter available, distributed through NPM package @opencensus/exporter-stackdriver

Installing the exporter

Install OpenCensus Stackdriver Exporter with:

npm install @opencensus/nodejs
npm install @opencensus/exporter-stackdriver

Creating the exporter

To create the exporter, you’ll need to:

• Have a GCP Project ID
• Have already enabled Stackdriver Tracing, if not, please visit the Code lab
• Enable your Application Default Credentials for authentication with:

export GOOGLE_APPLICATION_CREDENTIALS=path/to/your/credential.json

To create the exporter, in code:

const tracing = require('@opencensus/nodejs');
const { StackdriverTraceExporter } = require('@opencensus/exporter-stackdriver');

// Add your project id to the Stackdriver options
const exporter = new StackdriverTraceExporter({projectId: "your-project-id"});

tracing.registerExporter(exporter).start();
