What is @opentelemetry/instrumentation?

The @opentelemetry/instrumentation package is part of the OpenTelemetry project, which aims to provide a unified and standardized observability framework for monitoring applications' performance and behavior. This particular package offers a way to automatically instrument code to collect telemetry data such as traces and metrics, making it easier to monitor and debug applications.

What are @opentelemetry/instrumentation's main functionalities?

Automatic Instrumentation

Automatically instruments Node.js applications to collect telemetry data, such as tracing information for HTTP requests. This example shows how to set up the NodeTracerProvider and register the HttpInstrumentation to start collecting data.

const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');
const { HttpInstrumentation } = require('@opentelemetry/instrumentation-http');

const provider = new NodeTracerProvider();

registerInstrumentations({
  instrumentations: [
    new HttpInstrumentation()
  ],
  tracerProvider: provider,
});

Custom Instrumentation

Enables the creation of custom instrumentation for any library or application code not covered by the existing instrumentations. This example demonstrates how to extend the InstrumentationBase class to create a custom instrumentation.

const { InstrumentationBase } = require('@opentelemetry/instrumentation');

class MyCustomInstrumentation extends InstrumentationBase {
  constructor() {
    super('MyCustomInstrumentation');
  }

  init() {
    // Custom initialization logic
  }
}
