OpenTelemetry Connect Instrumentation for Node.js

This module provides automatic instrumentation for the connect module.

If total installation size is not constrained, it is recommended to use the @opentelemetry/auto-instrumentations-node bundle with @opentelemetry/sdk-node for the most seamless instrumentation experience.

Compatible with OpenTelemetry JS API and SDK 1.0+.

Status

Maturity	Component Owner	Compatibility
Unmaintained	N/A	API 1.0+ SDK 1.0+

Installation

This instrumentation relies on HTTP calls to also be instrumented. Make sure you install and enable both, otherwise you will have spans that are not connected to each other.

npm install --save @opentelemetry/instrumentation-http @opentelemetry/instrumentation-connect

Supported Versions

connect versions >=3.0.0 <4

Usage

OpenTelemetry Connect Instrumentation allows the user to automatically collect trace data and export them to their backend of choice, to give observability to distributed systems.

To enable a specific instrumentation, pass it to registerInstrumentations(). This is commonly done via NodeSDK for fully setting up all OpenTelemetry SDK components:

const { NodeSDK } = require('@opentelemetry/sdk-node');
const { HttpInstrumentation } = require('@opentelemetry/instrumentation-http');
const { ConnectInstrumentation } = require('@opentelemetry/instrumentation-connect');

const sdk = new NodeSDK({
  instrumentations: [
    // Connect instrumentation expects HTTP layer to be instrumented
    new HttpInstrumentation(),
    new ConnectInstrumentation(),
  ],
});
sdk.start();
process.once('beforeExit', async () => { await sdk.shutdown(); });
