Automatic DNS Query Instrumentation

This feature allows you to automatically instrument DNS queries in your Node.js application. The code sample demonstrates how to set up the DNS instrumentation using the OpenTelemetry SDK.

const { NodeTracerProvider } = require('@opentelemetry/sdk-trace-node');
const { registerInstrumentations } = require('@opentelemetry/instrumentation');
const { DnsInstrumentation } = require('@opentelemetry/instrumentation-dns');

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

registerInstrumentations({
  instrumentations: [
    new DnsInstrumentation(),
  ],
  tracerProvider: provider,
});
