-For distributed tracing in the Node.js v4 programming model, use the [`@azure/functions-opentelemetry-instrumentation`](https://www.npmjs.com/package/@azure/functions-opentelemetry-instrumentation) package instead of the Application Insights SDK. This package provides OpenTelemetry-based automatic instrumentation for Azure Functions. For more information, see the [OpenTelemetry Azure Functions Instrumentation for Node.js](https://github.com/Azure/azure-functions-nodejs-opentelemetry) GitHub repository.
