lab

This procedure is part of a lab that teaches you how to monitor your application with New Relic.

Each procedure in the lab builds upon the last, so make sure you've completed the last procedure, Query custom Business Data, before starting this one.

With your app reporting performance and custom business data, you now have full visibility in your application. Happy with your current experinece, you came to know about New Relic alerts, and you've decided to add them.

With alerts, you monitor your services and receive notifications about problems that you're interested in, so that you can react fast to troubleshoot and resolve them.

Create an alert policy

Before you set alert conditions, you must create a policy.

From Alerts & AI, go to Alert conditions (Policies) from the left-hand navigation. Then, click New alert policy.
