How to Integrate OpenTelemetry for NodeJS App

by

In this article we are going to cover How to Integrate OpenTelemetry for NodeJS App.

Prerequisites

  • Ubuntu 24.04 LTS
  • SSH access with sudo privileges
  • Install Node.js and NPM

Step#1:Install Node.js and NPM On Ubuntu 24.04 LTS

Please folllow below article to Install NodeJS and NPM On Ubuntu 24.04 LTS

How to Install NodeJS and NPM on Ubuntu 24.04 LTS

In the present Directory with name example-site execute below command.

npm init -y

Install Express dependencies.

npm install typescript \
  ts-node \
  @types/node \
  express \
  @types/express

# initialize typescript
npx tsc --init

Create and launch an HTTP Server, create a file name with app.ts and add the below code.

/*app.ts*/
import express, { Express } from 'express';

const PORT: number = parseInt(process.env.PORT || '8080');
const app: Express = express();

function getRandomNumber(min: number, max: number) {
  return Math.floor(Math.random() * (max - min) + min);
}

app.get('/rolldice', (req, res) => {
  res.send(getRandomNumber(1, 6).toString());
});

app.listen(PORT, () => {
  console.log(`Listening for requests on http://localhost:${PORT}`);
});

Run the application with the following command.

npx ts-node app.ts

open belwo URL in your web interface to ensure it is working.

Step #2:Integrate OpenTelemetry for NodeJS App

First, install the Node SDK and auto instrumentations package. The Node SDK lets you initialize OpenTelemetry with several configuration defaults that are correct for the majority of use cases.

The auto-instrumentations-node package installs instrumentation libraries that will automatically create spans corresponding to code called in libraries. In this case, it provides instrumentation for Express, letting the example app automatically create spans for each incoming request.

npm install @opentelemetry/sdk-node \
  @opentelemetry/api \
  @opentelemetry/auto-instrumentations-node \
  @opentelemetry/sdk-metrics \
  @opentelemetry/sdk-trace-node

The instrumentation setup and configuration must be run before your application code.

Create a file name with  instrumentation.ts which will contain your instrumentation setup code.

/*instrumentation.ts*/
import { NodeSDK } from '@opentelemetry/sdk-node';
import { ConsoleSpanExporter } from '@opentelemetry/sdk-trace-node';
import { getNodeAutoInstrumentations } from '@opentelemetry/auto-instrumentations-node';
import {
  PeriodicExportingMetricReader,
  ConsoleMetricExporter,
} from '@opentelemetry/sdk-metrics';

const sdk = new NodeSDK({
  traceExporter: new ConsoleSpanExporter(),
  metricReader: new PeriodicExportingMetricReader({
    exporter: new ConsoleMetricExporter(),
  }),
  instrumentations: [getNodeAutoInstrumentations()],
});

sdk.start();

Run your application as you normally would, but you can use the --require flag to load the instrumentation before the application code.

npx ts-node --require ./instrumentation.ts app.ts

Open in your web browser and reload the page a few times.
