@opentelemetry/instrumentation-net

OpenTelemetry Net module Instrumentation for Node.js

This module provides automatic instrumentation for the net 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.

Supports both TCP and IPC connections.

Compatible with OpenTelemetry JS API and SDK 1.0+.

Installation

npm install --save @opentelemetry/instrumentation-net

Usage

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

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

registerInstrumentations({
  instrumentations: [
    new NetInstrumentation(),
    // other instrumentations
  ],
});

Attributes added to connect spans
