#Node.js Auto-instrumentation

The Node.js auto-instrumentation provides automatic telemetry collection for Node.js applications, including popular frameworks like Express, Fastify, and Nest.js. This instrumentation captures traces, metrics, and logs from Node.js applications without requiring code modifications.

The Operator injects the OpenTelemetry Node.js automatic instrumentation into Node.js application containers, configuring it to instrument common libraries and frameworks automatically. This enables comprehensive observability for Node.js workloads running in Kubernetes.

#Enabling Node.js Instrumentation

To enable auto-instrumentation for Node.js applications, annotate your pod or namespace:

apiVersion: v1
kind: Pod
metadata:
  name: nodejs-app
  annotations:
    instrumentation.opentelemetry.io/inject-nodejs: "true"
spec:
  containers:
  - name: app
    image: mynodeapp:latest

The Operator will automatically inject the instrumentation components and configure the Node.js runtime to load them at startup.
