Azure Functions Node.js Open Telemetry Sample

This repo has a sample app that demonstrates using Open Telemetry with Azure Functions on Node.js. It has an HTTP trigger that also has an outbound request to httpbin.org to demonstrate a span within your function invocation. The code to setup open telemetry is in the src/index.ts or src/index.js file. There are several branches depending on your preferred configuration:

  • main: TypeScript example sending data to an OTLP endpoint.
  • main-js: JavaScript example sending data to an OTLP endpoint.
  • appinsights: TypeScript example sending data to an Azure App Insights endpoint.
  • appinsights-js: JavaScript example sending data to an Azure App Insights endpoint.

NOTE: You must be using Azure Functions Host v4.34+.

Run the app

  1. Create a free New Relic account (or any other product that supports Open Telemetry) to export your data to.

  2. Add a local.settings.json file. Assuming you're using New Relic, it will look like this:

    {
    "IsEncrypted": false,
    "Values": {
        "AzureWebJobsStorage": "",
        "FUNCTIONS_WORKER_RUNTIME": "node",
        "OTEL_EXPORTER_OTLP_ENDPOINT": "https://otlp.nr-data.net",
        "OTEL_EXPORTER_OTLP_HEADERS": "<api key information>"
    }
}

  3. Run npm install.

  4. Run npm start

  5. Execute your http trigger

  6. Go to the New Relic dashboard to see all your data!
