New Relic is a powerful web-based tool that allows you to track your web applications and microservices as well as other components, all in one place. It also provides valuable information on real-time performance. You can find out all about it here: What is New Relic and what can it be used for?

If you're ready to start using New Relic, just follow these steps:

Step 1 - Preparation

First, make sure that:

You have created an account on New Relic and have a free or paid plan
You have generated an INGEST – LICENSE API key

Step 2 - Enable PHP extension

Go to Websites → Manage on your hPanel, search for PHP Configuration on the sidebar and click on it:

The PHP Configuration option on Hostinger hPanel

Next, click on the PHP Extensions tab, scroll down to find newrelic and click on the checkbox to enable:

The PHP extensions tab on PHP Configuration section showing where to enable newrelic

Click on Save to apply the change, and it will be active in a couple of minutes.

Step 3 - Edit .htaccess file

Now that you have enabled the New Relic PHP extension, add the following lines to your .htaccess file:

php_value newrelic.license "license"
php_value newrelic.appname "test_app"

Make sure to replace license with the value of your New Relic INGEST – LICENSE key, and test_app with the name of your PHP application.

That's it! You will be able to view the performance reports right away by logging into your New Relic account's dashboard 😊
