OpenTelemetry NestJS Instrumentation for Node.js

NPM Published Version Apache License

This module provides automatic instrumentation for the Nest framework 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.

Compatible with OpenTelemetry JS API and SDK 1.0+.

Installation

npm install --save @opentelemetry/instrumentation-nestjs-core

Supported Versions

  • >=4.0.0

Usage

OpenTelemetry Nest Instrumentation allows the user to automatically collect trace data from the controller handlers and export them to the backend of choice.

To load a specific instrumentation (Nest in this case), specify it in the registerInstrumentations' configuration.

const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { NestInstrumentation } = require('@opentelemetry/instrumentation-nestjs-core');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');

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

registerInstrumentations({
  instrumentations: [
    new NestInstrumentation(),
  ],
});
