CakePHP New Relic Plugin

The New Relic plugin is a CakePHP plugin that makes your [New Relic] (https://newrelic.com) transactions easier to read and understand. It also gives you better flexibility in ignoring certain transactions (e.g., admin panels). By default, New Relic transactions are based on the file name and are hard to read. This plugin organizes them using basic routes, that is, a transaction for:

/posts/edit/2

is placed in the following New Relic transaction:

/posts/edit

This allows you to dig down into issues regarding certain actions, rather than based on filenames. To aggregate based on action, parameters are also ignored.

Requirements

CAKEPHP 2.0+
A New Relic Account
The New Relic agent on your server (enabled)

Installation

Manual

Download this: http://github.com/jeremyharris/cakephp-newrelic/zipball/master
Unzip that download.
Copy the resulting folder to app/Plugin/NewRelic/

GIT Submodule

In your app directory type:

git submodule add git://github.com/jeremyharris/cakephp-newrelic.git Plugin/NewRelic
git submodule update --init

Composer

Ensure require is present in composer.json. This will install the plugin into Plugin/NewRelic:

{
    "require": {
        "jeremyharris/cakephp-newrelic": "dev-master"
    }
}

Usage

Load the plugin:

CakePlugin::loadAll(); // or CakePlugin::load('NewRelic');

Add the following filter to your Dispatch filters (in `bootstrap.php):

Configure::write('Dispatcher.filters', array(
    'AssetDispatcher', //default
    'CacheDispatcher', //default
    'NewRelic.NewRelicFilter'
));

Transactions will now be named by basic routes, that is, :controller/:action.

Change the application name

Add the application name (in `bootstrap.php):

Configure::write('NewRelic.appName', 'My App Name');

Ignoring transactions

Sometimes you don't want to report something to New Relic. Things like importing take a while, and can mess up your averages. Admin panels are also an example of something you may not want to report to New Relic. You can ignore transactions based on routes like so:

Configure::write('NewRelic.ignoreRoutes', array(
     '/admin/:controller/:action/*',
     '/users/import'
));

NewRelic.ignoreRoutes uses the Routing system, so use them as you would connecting a route in your routes.php file.

Real User Monitoring (RUM)

If you want to use New Relic's RUM, there's a little helper that let's you do that. Add the helper to your controller:

public $helpers = array(
    'NewRelic.NewRelic'
);

Then add the following to your layout:

<!DOCTYPE html>
<html>
  <head>
  <?php echo $this->NewRelic->start(); ?>
  ...
  </head>
  <body>
  ...
  <?php echo $this->NewRelic->end(); ?>
  </body>
</html>
