OpenTelemetry Connect Instrumentation for Node.js

This module provides automatic instrumentation for the connect module, which may be loaded using the @opentelemetry/sdk-trace-node package and is included in the @opentelemetry/auto-instrumentations-node bundle.

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.

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

• ^3.0.0

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 load the instrumentation, specify it in the Node Tracer's configuration:

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

const provider = new NodeTracerProvider();
provider.register();

registerInstrumentations({
  instrumentations: [
    // Connect instrumentation expects HTTP layer to be instrumented
    new HttpInstrumentation(),
    new ConnectInstrumentation(),
  ],
});

See examples/connect for a short example.
