OpenCensus Stackdriver Exporter for Node.js

OpenCensus Stackdriver Exporter allows the user to send collected traces with OpenCensus Node.js and stats with OpenCensus Core to Stackdriver Cloud Tracing and Stackdriver Monitoring.

The library is in alpha stage and the API is subject to change.

OpenCensus Stackdriver Trace Exporter

Installation

Install OpenCensus Stackdriver Exporter with:

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

Usage

To use Stackdriver as your exporter, make sure you have enabled Stackdriver Tracing on Google Cloud Platform. Enable your Application Default Credentials for authentication with:

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

Create and register the exporter on your application and pass your Project ID.

For Javascript:

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();

Similarly for TypeScript:

import * as tracing from '@opencensus/nodejs';
import { StackdriverTraceExporter } from '@opencensus/exporter-stackdriver';

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

Now, register the exporter and start tracing.

tracing.start({'exporter': exporter});

or

tracing.registerExporter(exporter).start();

Viewing your traces:

With the above you should now be able to navigate to the Stackdriver UI at: https://console.cloud.google.com/traces/traces

const { StackdriverStatsExporter } = require('@opencensus/exporter-stackdriver');

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

// Pass the created exporter to Stats
globalStats.registerExporter(exporter);

Similarly for TypeScript:

import { globalStats } from '@opencensus/core';
import { StackdriverStatsExporter } from '@opencensus/exporter-stackdriver';

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

// Pass the created exporter to Stats
globalStats.registerExporter(exporter);
