<p>MySQL Profiler displays debugging information about SQL queries to admin WordPress users.  For each query, the profiler displays the time, syntax-highlighted SQL, and a trace of the functions (as well as the file and line number that the functions were called from) that were called.</p>
<p>The list can be sorted by any of its columns, so you can, for example:</p>
<ul>
<li>Order the list by ID to see the chronological order of the queries</li>
<li>Order the list by time to see the slowest queries</li>
<li>Order the list by query to group the queries by type (SELECT, UPDATE, etc)</li>
<li>Order the list by trace to group the queries by similar origins</li>
</ul>
<p>The list can also filtered by typing in the search box, so you can, for example:</p>
<ul>
<li>View all queries that use the wp_posts table</li>
<li>View all queries that are related to the use of a function in taxonomy.php</li>
<li>View all queries that are related to the use of a specific function or class</li>
<li>View all queries that call a specific MySQL function</li>
</ul>
<p>To turn off syntax highlighting, put the following in wp-config.php:</p>
<pre><code>define('MP_HIGHLIGHT_SYNTAX', false);
</code></pre>
<p>To omit the file and line number from the function trace and display the functions as a comma-separated list (to save vertical space), define the following in wp-config.php:</p>
<pre><code>define('MP_DISPLAY_FILES', false);
</code></pre>
<p>This plugin was loosely based on <a href="http://bueltge.de/" rel="nofollow ugc">Frank Bueltge</a>‘s <a href="https://wordpress.org/extend/plugins/debug-queries/" rel="ugc">Debug Queries</a> plugin, so a hearty thanks to him for the development of that.</p>

<h4>Only for development!</h4>
<h4>Now with OPcache memory consumption support</h4>
<p>This plugin dumps the colorized filenames and memory consumptions or file sizes after the normal WordPress HTML output, after the closing html tag. This generates invalid HTML but gives you an overview of loaded plugins and the current theme.</p>
<p><em>What’s running</em> lists all files parsed and executed by the PHP engine. It can be used for plugin or theme refactoring.</p>
<h4>Now you can highlight your own plugin and theme</h4>
<p>Provide a part of its path in wp-config.php:</p>
<pre><code>define( 'WHATS_RUNNING_HIGHLIGHT', 'wp-content/plugins/my-plugin' ); </code></pre>
<h4>Color codes</h4>
<ul>
<li>your code is highlighted with YELLOW background</li>
<li>plugin files are in BLUE</li>
<li>themes files are in ORANGE</li>
<li>files in the wp-includes directory are in GREEN</li>
<li>files in the wp-admin directory are in GREY</li>
<li>all other files are in RED</li>
<li>VIOLET bar after the filename represents the file size ( 0.5 kB/px )</li>
<li>DARK MAGENTA bar after the filename represents the OPcache memory consumption ( 1 kB/px )</li>
</ul>
