Replaces the default text in the Debug Bar button (which is “Debug Bar” by default in English) with the page’s query count and total sql time. The button will be red if there were more than 200 queries or they took more than 1 second to run, and orange if the page required more than 100 queries or took more than 0.5 seconds to run.
Requires the <a href="https://wordpress.org/plugins/debug-bar-console/" rel="ugc">Debug Bar plugin</a> and for the constant <code>SAVEQUERIES</code> to be true.
Inspired by the Admin Bar on WordPress.com VIP, which offers similar functionality.

Debug Bar Query Count Alert

A simple add-on for the Debug Bar plugin to replace the button text with the database query count and time.

Debug Bar Cron adds information about WP scheduled events to a new panel in the Debug Bar. This plugin is an extension for 
Debug Bar and thus is dependent upon Debug Bar being installed for it to work properly.
Once installed, you will have access to the following information:
<ul>
<li>Number of scheduled events</li>
<li>If cron is currently running</li>
<li>Time of next event</li>
<li>Current time</li>
<li>List of custom scheduled events</li>
<li>List of core scheduled events</li>
<li>List of schedules</li>
</ul>

Debug Bar Cron

This has been great for checking if WordPress's scheduled events are firing. Good for checking if you need to setup a real cron job or if that real cron job is failing. Very clear presentation.

Great for checking if scheduled events running

Debug Bar Cron adds a new panel to Debug Bar that displays information about WP scheduled events.
