Holdenovi_Profiler

Description

A Magento 2 profiler based on AOE_Profiler for Magento 1

Installation via GitHub

git clone -b master git@github.com:perryholden/Holdenovi_Profiler.git app/code/Holdenovi/Profiler
bin/magento module:enable Holdenovi_Profiler
bin/magento setup:upgrade
bin/magento cache:flush

Installation via Composer

composer config repositories.holdenovi_profiler vcs https://github.com/perryholden/Holdenovi_Profiler.git
composer require holdenovi/module-profiler
bin/magento module:enable Holdenovi_Profiler
bin/magento setup:upgrade
bin/magento cache:flush

Configuration

To enable the profiler:

  1. Copy the holdenovi_profiler.xml.sample file to var/holdenovi_profiler.xml and configure based on XML file comments.
  2. Disable the full-page and block caches: bin/magento cache:disable full_page block_html
  3. Run the following command: bin/magento dev:profiler:enable '{"drivers":[{"type":"Holdenovi\\Profiler\\Driver\\Hierarchy"}]}'
    • NOTE: You will see a message stating Type {"drivers":[{"type":"Holdenovi\Profiler\Driver\Hierarchy"}]} is not one of the built-in output types (html, csvfile).. This is just a warning message, and it does not prevent the profiler from being enabled.

To view the profile results grid, navigate in admin to SYSTEM → Tools → Holdenovi Profiler

Enable database profiling (optional)

Add this to your env.php under db → connection → default:

'profiler' => [
    'class' => '\\Magento\\Framework\\DB\\Profiler',
    'enabled' => true
],

Notes

Depending on the complexity of your site a lot of data ends up being collected during a profile run. The first problem with this is that the database table holding this information might be growing. Please double check the cron settings of the cleanup task.

By default MySQL comes with max_allowed_packet set to 1 MB. One profile run could exceed 1 MB. Please check var/log/system.log for error messages and increase this setting in your MySQL server configuration. (Also see: https://dev.mysql.com/doc/refman/8.0/en/packet-too-large.html)
