Automatically Label Code Changes in New Relic using Quicksilver Hooks	A guide to integrating Pantheon and New Relic for deployment labeling.	siteintegrations	guide	docs/guides/:basename/	5/1/2017	scottmassey

New Relic is a powerful tool for monitoring the performance of a WordPress or Drupal site. It provides insight into how efficiently a website is using resources, and where improvements can be made in the application. Pantheon offers New Relic Pro within the Site Dashboard on all sites for free.

In this guide, we'll automatically label code changes to your site in New Relic's Deployment page using Pantheon's Quicksilver hooks. This creates a traceable connection between performance changes and code deployments, allowing developers to see if a code change positively or negatively impacted performance.

Activate New Relic Pro

1. From the Site Dashboard, click New Relic.
2. Click Activate New Relic Pro. The Site Dashboard will begin showing New Relic data shortly after an environment receives web requests.
3. Click the Go to New Relic button.

Configure Quicksilver Hook to Record Deployments

Next, we'll use Pantheon's Quicksilver hooks to run our example New Relic script immediately after code is synced on Dev or a Multidev environment and after code is deployed to Test and Live. The script configured in this guide applies a label to the Deployment page in New Relic.

In the commands below, replace <site> with your Pantheon site name.

1. If you haven't done so already, clone your Pantheon site repository and navigate to the project's root directory:

    `terminus connection:info <site>.dev --fields='Git Command' --format=string`
    cd <site>
   

2. Set the connection mode to Git:

    terminus connection:set <site>.dev git
   

3. Create a copy of Pantheon's new_relic_deploy.php script in the project's private path:

   mkdir private
   mkdir private/scripts
   curl https://raw.githubusercontent.com/pantheon-systems/quicksilver-examples/master/new_relic_deploy/new_relic_deploy.php --output ./private/scripts/new_relic_deploy.php

4. Create a pantheon.yml file if one doesn't already exist in your root directory.

5. Paste the following workflow into your pantheon.yml file to hook into the platform after code is synced on Dev/Multidev and deployed to Test/Live to fire off the New Relic integration script:

  api_version: 1

  workflows:
    # Log to New Relic when deploying to test or live.
    deploy:
      after:
        - type: webphp
          description: Log to New Relic
          script: private/scripts/new_relic_deploy.php
    # Also log sync_code so you can track new code going into dev/multidev.
    sync_code:
      after:
        - type: webphp
          description: Log to New Relic
          script: private/scripts/new_relic_deploy.php

api_version should be set once in pantheon.yml. If you have an existing pantheon.yml with this line, don't add it again.

6. Add, commit and push changes to the Dev environment:

    git add private/scripts/new_relic_deploy.php
    git commit -am "Adding deployment recording to New Relic"
    git push origin master
   

   In the terminal, you should see that your pantheon.yml file is being applied. Even this initial code push should appear in your Dev environment's New Relic account, on the Deployments tab:

   

   You can also view deployments from the Overview tab:

   

7. Once you've tested and confirmed there are no issues, deploy your new commit to Test and Live. From now on, your deploys will be recorded in New Relic.

Conclusion

This is a fast way to integrate New Relic and Pantheon. The Quicksilver Examples repository provides many more ways to automate development, so please take advantage of them and extend them to fit your workflow.
