Package Exports

@opentelemetry/plugin-http

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@opentelemetry/plugin-http) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

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.
