Xhprof Profiler for Magento 2

Overview

This module integrates Xhprof profiling capabilities into your Magento 2 application. It provides an easy way to profile and analyze your application's performance by tracking and storing profiling data.

Requirements

Magento 2.4.7 or higher
Xhprof PHP extension
Compatible with Buggregator

Installation

Install via composer:

composer require justbetter/magento2-xhprof-profiler

Enable the module:

bin/magento module:enable JustBetter_XhprofProfiler

Run setup upgrade and di compile:

bin/magento setup:upgrade
bin/magento setup:di:compile

Configuration

Configure the module by adding the following configuration to your app/etc/env.php file:

return [
    // ... other configurations ...
    'xhprofprofiler' => [
        'app_name' => 'Magento 247',
        'endpoint' => 'http://exciting_chatelet.orb.local/profiler/store'
    ],
];

app_name: The name of your application.
endpoint: The endpoint where the profiling data will be stored.

Usage

The profiling is automatically enabled for all requests. The module uses the AppInterfacePlugin to start and terminate the profiler around each request.

Key Classes and Methods

XhprofProfiler
- Constants:
  - HEADER: The header key used to enable Xhprof profiling.
  - IGNORED_FUNCTIONS_KEY: The key for ignored functions in the profiler.
- Methods:
  - __construct(): Initializes the profiler with the given driver, deployment configuration, and optional tags.
  - handle(): Starts the profiler.
  - terminate(): Ends the profiler and stores the profiling data.
AppInterfacePlugin
- Methods:
  - aroundLaunch(): Wraps around the application launch to start and stop the profiler.

Buggregator Compatibility

This module is compatible with Buggregator, a debug and profiler tool for PHP applications. Buggregator can collect and visualize profiling data generated by this module, providing a comprehensive debugging and performance analysis experience.

To integrate with Buggregator:

Ensure Buggregator is installed and configured in your environment.
Configure the endpoint in app/etc/env.php to point to Buggregator's profiling data endpoint.

Example configuration:

return [
    // ... other configurations ...
    'xhprofprofiler' => [
        'app_name' => 'Magento 247',
        'endpoint' => 'http://your_buggregator_instance/profiler/store'
    ],
];

Example

Here is an example of how the profiler is used in the plugin:

namespace JustBetter\XhprofProfiler\Plugin;

use JustBetter\XhprofProfiler\Model\Profiler\XhprofProfiler;
use Magento\Framework\App\ResponseInterface;
use Magento\Framework\AppInterface as Application;

class AppInterfacePlugin
{
    public function __construct(
        protected XhprofProfiler $profiler
    )
    {
    }

    public function aroundLaunch(
        Application $subject,
        callable $proceed,
    ) : ResponseInterface {
        $this->profiler->handle();
        $response = $proceed();
        $this->profiler->terminate();
        return $response;
    }
}

Exception Handling

The terminate method of the XhprofProfiler class can throw the following exceptions:

FileSystemException: If there is an issue with the file system.
RuntimeException: If there is a runtime issue.

Ensure you have proper exception handling in place when integrating this module.
