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
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(),
],
});
