Azure OpenTelemetry Instrumentation library for JavaScript

Getting started

Currently supported environments

See our support policy for more details.


You'll need to configure the OpenTelemetry SDK in order to produce Telemetry data. While configuring OpenTelemetry is outside the scope of this README, we encourage you to review the OpenTelemetry documentation in order to get started using OpenTelemetry.

Install the @azure/opentelemetry-instrumentation-azure-sdk package

Install the Azure OpenTelemetry Instrumentation client library with npm:

npm install @azure/opentelemetry-instrumentation-azure-sdk

Browser support

JavaScript Bundle

To use this client library in the browser, first you need to use a bundler. For details on how to do this, please refer to our bundling documentation.

Key concepts

  • The createAzureSdkInstrumentation function is the main hook exported by this library which provides a way to create an Azure SDK Instrumentation object to be registered with OpenTelemetry.


Enable OpenTelemetry instrumentation

const { registerInstrumentations } = require("@opentelemetry/instrumentation");
const { createAzureSdkInstrumentation } = require("@azure/opentelemetry-instrumentation-azure-sdk");

// Set-up and configure a Node Tracer Provider using OpenTelemetry
const opentelemetry = require("@opentelemetry/api");
const { NodeTracerProvider } = require("@opentelemetry/sdk-trace-node");
const { SimpleSpanProcessor, ConsoleSpanExporter } = require("@opentelemetry/tracing");

const provider = new NodeTracerProvider();
provider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));

  instrumentations: [createAzureSdkInstrumentation()],

// Continue to import any Azure SDK client libraries after registering the instrumentation.

const { KeyClient } = require("@azure/keyvault-keys");
const keyClient = new KeyClient(url, new DefaultAzureCredential()); 

async function main() {
  // Tracing is now enabled using automatic span propagation with an active context.
  await keyClient.getKey("MyKeyName");

  // If your scenario requires manual span propagation, all Azure client libraries
  // support explicitly passing a parent context via an `options` parameter.
  // Get a tracer from a registered provider, create a span, and get the current context.
  const tracer = opentelemetry.trace.getTracer("my-tracer");
  const span = tracer.startSpan("main");
  const ctx = opentelemetry.trace.setSpan(opentelemetry.context.active(), span);

  await keyClient.getKey("MyKeyName", {
    tracingOptions: {
      // ctx will be used as the parent context for all operations.
      tracingContext: ctx,



Enabling logging may help uncover useful information about failures. In order to see a log of HTTP requests and responses, set the AZURE_LOG_LEVEL environment variable to info. Alternatively, logging can be enabled at runtime by calling setLogLevel in the @azure/logger:

const { setLogLevel } = require("@azure/logger");


For more detailed instructions on how to enable logs, you can look at the @azure/logger package docs.
