Debug Bar

Description

Adds a debug menu to the admin bar that shows query, cache, and other helpful debugging information.

A must for developers!

When WP_DEBUG is enabled it also tracks PHP Warnings and Notices to make them easier to find.

When SAVEQUERIES is enabled the mysql queries are tracked and displayed.

To enable these options, add the following code to your wp-config.php file:

define( 'WP_DEBUG', true );
define( 'SAVEQUERIES', true );

Add a PHP/MySQL console with the Debug Bar Console plugin.

There are numerous other add-ons available to get more insight into, for instance, the registered Post Types, Shortcodes, WP Cron, Language file loading, Actions and Filters and so on. Just search the plugin directory for ‘Debug Bar’.

Not really useful

You can see only few informations and you have to set WP_DEBUG, that you can not use in production environment. There are other debug plugins, those are much better.
