## README

# OpenTelemetry Net module Instrumentation for Node.js

[![NPM Published Version][npm-img]][npm-url]
[![Apache License][license-image]][license-image]

This module provides automatic instrumentation for the [`net`](http://nodejs.org/dist/latest/docs/api/net.html) module.

If total installation size is not constrained, it is recommended to use the [`@opentelemetry/auto-instrumentations-node`](https://www.npmjs.com/package/@opentelemetry/auto-instrumentations-node) bundle with [@opentelemetry/sdk-node](https://www.npmjs.com/package/@opentelemetry/sdk-node) for the most seamless instrumentation experience.

Compatible with OpenTelemetry JS API and SDK `1.0+`.

Supports both TCP and IPC connections.

## Installation

```bash
npm install --save @opentelemetry/instrumentation-net
```

## Supported Versions

- Node.js `>=14`

## Usage

```js
const { NodeSDK } = require('@opentelemetry/sdk-node');
const { NetInstrumentation } = require('@opentelemetry/instrumentation-net');

const sdk = new NodeSDK({
  instrumentations: [
    new NetInstrumentation(),
  ],
});
sdk.start();
process.once('beforeExit', async () => { await sdk.shutdown(); });
```

## Semantic Conventions

This instrumentation uses stable semantic conventions for networking attributes.

The `instrumentation-net` versions 0.64.0 and later emit the stable v1.23.0+ semantic conventions.
