Setup Opentelemetry with node JS – Tracer and Jaeger integration
A tutorial by Habibul Hasan
Introduction
Opentelemetry is a powerful tool for tracing requests in distributed systems. In this tutorial, we’ll learn how to setup Opentelemetry with node JS using a Tracer and Jaeger integration. This will help us monitor and trace requests in our node JS application.
Step 1: Install Opentelemetry package
First, we need to install the Opentelemetry package in our node JS application. You can do this by running the following command:
npm install @opentelemetry/api
Step 2: Configure Opentelemetry Tracer
Next, we need to configure the Opentelemetry Tracer in our application. You can do this by setting up a Tracer provider and registering it with the global Tracer registry. Here’s an example code snippet to do this:
const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { SimpleSpanProcessor } = require('@opentelemetry/tracing');
const { JaegerExporter } = require('@opentelemetry/exporter-jaeger');
const provider = new NodeTracerProvider();
const exporter = new JaegerExporter();
provider.addSpanProcessor(new SimpleSpanProcessor(exporter));
provider.register();
Step 3: Integrate with Jaeger
Finally, we need to integrate our Opentelemetry Tracer with Jaeger, which is a popular tracing backend. You can do this by providing the Jaeger exporter with the necessary configuration options. Here’s an example code snippet to do this:
const exporter = new JaegerExporter({
serviceName: 'my-node-js-app',
endpoint: 'http://jaeger-collector:14268/api/traces'
});
Conclusion
That’s it! You have successfully setup Opentelemetry with node JS using a Tracer and Jaeger integration. Now you can monitor and trace requests in your node JS application with ease. Happy coding!
