PhpPerfTools Collector

This is a small standalone module which you can use to collect and store XHProf or Uprofiler or Tideways performance data for later usage in GUI.

Goals

• Compatibility with PHP >= 5.3.0
• No dependencies aside from the relevant extensions
• Customizable and configurable so you can build your own logic on top of it

Usage

Profile an Application or Site

The simplest way to profile an application is to use external/header.php. external/header.php is designed to be combined with PHP's auto_prepend_file directive. You can enable auto_prepend_file system-wide through php.ini. Alternatively, you can enable auto_prepend_file per virtual host.

With apache this would look like:

<VirtualHost *:80>
  php_admin_value auto_prepend_file "/Users/markstory/Sites/xhgui/external/header.php"
  DocumentRoot "/Users/markstory/Sites/awesome-thing/app/webroot/"
  ServerName site.localhost
</VirtualHost>

With Nginx in fastcgi mode you could use:

server {
  listen 80;
  server_name site.localhost;
  root /Users/markstory/Sites/awesome-thing/app/webroot/;
  fastcgi_param PHP_VALUE "auto_prepend_file=/Users/markstory/Sites/xhgui/external/header.php";
}

Profile a CLI Script

The simplest way to profile a CLI is to use external/header.php. external/header.php is designed to be combined with PHP's auto_prepend_file directive. You can enable auto_prepend_file system-wide through php.ini. Alternatively, you can enable include the header.php at the top of your script:

<?php
require '/path/to/xhgui/external/header.php';
// Rest of script.

You can alternatively use the -d flag when running php:

php -d auto_prepend_file=/path/to/xhgui/external/header.php do_work.php

Use with environment variables

• run composer require perftools/xhgui-collector
• include these lines into your bootstrap file (e.g. index.php)

define('XHGUI_CONFIG_DIR', PATH_TO_OWN_CONFIG);
require_once PATH_TO_YOUR_VENDOR . '/perftools/xhgui-collector/external/header.php';

• set environment variables to configure profiling behaviour

env	description	example	default
PHPPERFTOOLS_PROFILING_RATIO	the ratio of profiled requests	PHPPERFTOOLS_PROFILING_RATIO=50 which profiles 50% of all requests	PHPPERFTOOLS_PROFILING_RATIO=100
PHPPERFTOOLS_PROFILING	if this env var is set with any value the profiling is enabled	PHPPERFTOOLS_PROFILING=enabled	it is not set per default, so no profiling will be triggered

System Requirements

For using the data collection classes you will need the following:

• PHP version 5.3 or later.
• XHProf, Uprofiler or Tideways to actually profile the data.
• Some way to store data. Choose either:
  • MongoDB Extension>=1.3.0 (MongoDB PHP driver from pecl) and alcaeus/mongo-php-adapter composer dependency,
  • PDO. This package is tested with SQLite (without native json), MySQL (with and without native json) and PostgreSQL with native json,
  • files in a directory
  • upload to GUI instance

When in doubt, refer to PhpPerfTools/GUI repository's composer.json or this repository's composer.json suggests section.
