Install New Relic Node.js agent in GAE flexible environment

With New Relic's Node.js agent, you can monitor applications that reside in the Google App Engine (GAE) flexible environment. Adding New Relic to your GAE flex app gives you insight into the health and performance of your app and extends GAE with metrics you can view in APM and browser monitoring.

This document explains how to add New Relic to your GAE flex app using either of these methods:

Use native deploy

To use Google App Engine's "native mode" installation with your Node.js app:

  1. Follow standard procedures to install New Relic's Node.js agent, including your license key. Be sure to save the newrelic module to the package.json file.

  2. Follow Google App Engine procedures for Node.js to create a new Cloud Platform project, create an App Engine application, and complete other prerequisites for the Google Cloud SDK.

  3. Optional: Set environment variables to configure the Node.js agent's GAE app.yaml file.

  4. Use the Google Cloud SDK's gcloud command line tool to deploy GAE apps. To deploy your Node.js app to your initialized GAE flexible environment, run the following command:

    gcloud --project new-relic-apm-nodejs app deploy

Google App Engine automatically includes your Node.js app's newrelic.js configuration file in the deployed package. Wait until the deployment completes, then view your GAE flex app data in the APM Summary page.

Build a custom runtime

See Google's documentation for building custom runtimes. This example describes how to add New Relic to your GAE flex app by building a custom runtime for Docker. You can deploy the app without any special configuration.

For more information about deploying and configuring your Node.js app in the GAE flexible environment, see:

Optional: Disable health checks

Google App Engine sends periodic health check requests to confirm that an instance has been successfully deployed, and to check that a running instance maintains a healthy status. A health check is an HTTP request to the URL /_ah/health.

If you create a custom runtime, your app must be able to handle a large number of health check requests. Otherwise, your app data may not display correctly in APM.

If you notice performance issues, disable GAE health checks. In your app.yaml, add:

enable_health_check: False
