Debug Toolbar

This module adds a Debug Toolbar in Magento 2. The toolbar displays useful information about the last executions (including ajax requests, rest API and graphql):

• HTTP Request/response
• SQL queries (with the PHP trace for each query)
• Profiler information (with timers)
• Layout information
• Cached items
• Plugins/observers that were triggered

To install the module:

1. Execute the following command at the root of the Magento installation:

   composer require --dev smile/module-debug-toolbar

2. Enable the module:

   bin/magento module:enable Smile_DebugToolbar
   bin/magento setup:upgrade

3. Enable the toolbar:

   bin/magento config:set smile_debugtoolbar/configuration/enabled 1
   

The configuration of the module is available in the section Smile > Smile DebugToolbar of the admin area:

You can:

• Enable / disable the debug toolbar (default: disabled)
• Show / hide the debug toolbar in the admin area (default: hidden)
• Choose the number of last executions to save and display in the toolbar (default: 5)

Unfortunately, the module cannot be automatically uninstalled, because Magento doesn't support uninstallation of dev packages out of the box.

To uninstall the module, follow these steps:

1. In app/etc/env.php, remove the key db.connection.default.profiler from the array if it is defined.
2. Run the following commands:

   bin/magento module:disable Smile_DebugToolbar
   composer remove --dev smile/module-debug-toolbar
   bin/magento setup:upgrade
   

3. [Optional] Remove the directory "var/smile_toolbar".

It is possible to add new zones to the toolbar (e.g. to display project-specific data). This is documented here.
