OpenTelemetry HTTP Instrumentation for Node.js

This module provides automatic instrumentation for http.

For automatic instrumentation see the @opentelemetry/node package.

Installation

npm install --save @opentelemetry/plugin-http

Usage

OpenTelemetry HTTP 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 a specific plugin (HTTP in this case), specify it in the Node Tracer's configuration.

const { NodeTracerProvider } = require('@opentelemetry/node');

const provider = new NodeTracerProvider({
  plugins: {
    http: {
      enabled: true,
      // You may use a package name or absolute path to the file.
      path: '@opentelemetry/plugin-http',
      // http plugin options
    }
  }
});

To load all of the supported plugins, use below approach. Each plugin is only loaded when the module that it patches is loaded; in other words, there is no computational overhead for listing plugins for unused modules.

const { NodeTracerProvider } = require('@opentelemetry/node');

const provider = new NodeTracerProvider();

See examples/http for a short example.
