Sample Attributes & Events Application

This example provides an application to demonstrate how to share custom attributes and events. This application is helpful for users who want to send custom attributes and events in a web framework transaction.

Getting Started

  1. Clone or fork this repository.
  2. Navigate to this example's sub directory 
    cd newrelic-node-examples/custom-instrumentation/attributes-events-metrics
  3. Install dependencies and run application. 
    npm install
cp env.sample .env
# Fill out `NEW_RELIC_LICENSE_KEY` in .env and save 
# Start the application
npm start
  4. Make requests to the application. Route names include: 'custom-attribute', 'custom-attributes', 'custom-span-attribute', 'custom-span-attributes', 'custom-event', and custom-metric. 
    curl -X POST http://localhost:3000/custom-attribute

Exploring Telemetry

After sending a few requests, navigate to your application in APM & Services. Locate the 'Example Attributes, Events & Metrics App' service and then select Transactions on the left-side of the screen. You should see your requests in a few minutes in a similar fashion to below.

If you expand the transaction, you should see 'Nodejs/ ... //custom-attribute'. Select 'Attributes' on the right side of your screen; scroll down the list of attributes to find your custom attribute. Notice 'hello: world' in the below example.
