The New Relic PHP agent monitors your application to help you identify and solve performance issues. You can also extend the agent's performance monitoring to collect and analyze business data to help you improve the customer experience and make data-driven business decisions.
Before you install the PHP agent, ensure your system meets the system requirements. The PHP agent supports many of the most common PHP frameworks, databases, and libraries. You can also use the PHP agent in a Google App Engine (GAE) flexible environment.

- Send your own event data
- Create and share customizable, interactive dashboards
Install the agent
If you are installing the agent on a shared hosting service, ensure you have root permissions to install the agent or contact your hosting provider for technical assistance.
For standard installations, see:
- PHP agent installation overview (the basic installation steps for the most common setups).
- Installing on RedHat or CentOS
- Installing on Ubuntu or Debian
- Installing with tar archive (generic method to use on any supported systems such as Linux variants, OpenSolaris, SmartOS, FreeBSD, Mac OS X, etc)
- The newrelic-install script (how to use the interactive script that automates some installation tasks)
For other types of PHP installations and advanced installation topics, see:
- PHP agent installation: Non-standard PHP
- Starting the PHP daemon (a standard New Relic installation starts the daemon automatically, but you can also start the daemon manually)
- Silent mode for the install script
- Google App Engine (GAE) flex environment installation for New Relic's PHP agent
Configure the agent
The agent includes a variety of configuration options to further customize and fine-tune your installation.
The most important part of agent configuration is to give your app a descriptive name. New Relic uses this app name to aggregate metrics when you have multiple apps or hosts.
After changing any agent configuration options, restart your web server.
Extend agent instrumentation
After installing the agent, go further and extend the agent's instrumentation:
- Page load timing: Integrate the PHP agent with New Relic Browser to gain visibility into end-user activity.
- Custom instrumentation: Instrument transactions not captured as part of our framework instrumentation.
- Agent API: Use the agent API to customize the agent's behavior. For example, you can collect custom metrics, flag an error, or ignore a particular transaction entirely.
- Agent attributes: Customize the attributes attached to transactions. Customizing attributes allows you to avoid sending sensitive attributes, or to collect additional attributes for deeper visibility into your transactions.
Troubleshoot your installation
If you encounter issues with the PHP agent, see our full list of troubleshooting documentation. Common installation issues include:
- No data appears (PHP)
- Determining permissions requirements
- INI settings not taking effect immediately
