<p>CodeTelemetryLab Admin Performance Inspector is a developer-focused performance profiling plugin built exclusively for the WordPress admin area. It instruments the WordPress request lifecycle in real time and presents all profiling data inside a clean, dedicated dashboard under Tools <span aria-hidden="true" class="wp-exclude-emoji">→</span> Admin Performance Inspector.</p>
<p>No configuration needed. Activate the plugin and instantly see what is slowing down your WordPress backend.</p>
<h4>What It Profiles</h4>
<p><strong>Admin Page Execution Time</strong><br />
Measures total request time from plugins_loaded to shutdown using microtime(true). Displays the precise execution time in milliseconds on the overview panel.</p>
<p><strong>Plugin Load Performance</strong><br />
Tracks the execution time of every active plugin using a lightweight MU-plugin drop-in. Displays a sortable table of all plugins with their individual load times and flags slow-loading plugins automatically.</p>
<p><strong>Database Query Profiling</strong><br />
Captures every SQL query executed during the admin request using WordPress’s native SAVEQUERIES constant. Displays total query count, slow query count, cumulative query time, and a full query list with origin file and line number. Slow queries (default threshold: 100ms) are visually flagged.</p>
<p><strong>Hook Execution Profiling</strong><br />
Times key WordPress hooks including init, admin_init, admin_menu, current_screen, and wp_loaded. Shows execution time and registered callback count for each hook.</p>
<p><strong>Memory Usage Monitoring</strong><br />
Displays current memory usage, peak memory usage, and percentage of PHP memory limit consumed — with a visual progress bar.</p>
<h4>Who Is This For?</h4>
<ul>
<li>WordPress developers diagnosing slow admin dashboards</li>
<li>Site administrators troubleshooting plugin conflicts</li>

<p>You can use this plugin to manually log data or to capture logging on WordPress actions. You can capture load time, memory, backrace, data dumps, urls, and server IPs.</p>
<p>This is designed to either be managed using wp-config.php and logging OR using the admin and debugbar plugin ( https://wordpress.org/extend/plugins/debug-bar/ ). Most of the following documentation applies equally to the settings panel or the wp-config.php vars.  Either one works fine. The only exception is the DEBUG_LOG configuration which is only supported as a wp-config var.</p>
<p>Firstly, you can manually log things using the following function:</p>
<pre><code>do_action( 'log', $message, $group, $data );
</code></pre>
<p>The $group allows you to selectively output logging based on groups of log messages. The $message is the string you want to see in the log. $data is an optional parameter for the data that you want to display in the log (objects, arrays, or any other sort of data really).</p>
<p>To render messages to the log, you must configure wp-config.php as follows:</p>
<p>Run debug on only these groups. Use ‘ALL’ to debug everything. The group ‘ACTIONS’ is reserved for WordPress actions.</p>
<pre><code>define( 'DEBUG_GROUPS', 'ACTIONS,default,myspecialgroup' );
</code></pre>
<p>Display these outputs in the log for each log message.</p>
<pre><code>define( 'DEBUG_PARAMS', 'time,timedelta,memory,memorydelta,data,backtrace,url,server' );
</code></pre>
<p>WordPress actions that you wish to log.</p>
<pre><code>define( 'DEBUG_ACTIONS', 'wp_head,switch_theme,wp_footer' );
</code></pre>
<p>Optional restriction by URL (useful on MU installs).</p>
<pre><code>define( 'DEBUG_URLS', 'myurl.com' );
</code></pre>
<p>Minimum time in milliseconds required to register a log entry as being slow. Default 0 for no minumum.</p>
<pre><code>define( 'DEBUG_MIN_TIME', 500 );
</code></pre>
<p>Minimum memory in killobytes required to register a log entry as being heavy. Default 0 for no minumum.</p>
<pre><code>define( 'DEBUG_MIN_MEM', 1024 );
</code></pre>
<p>Path to log file or set to TRUE to use php error log. Default FALSE for no logging.</p>
<pre><code>define( 'DEBUG_LOG', '/path/to/writable/log/file' );
</code></pre>
<p>or</p>
<pre><code>define( 'DEBUG_LOG', TRUE );
</code></pre>
<h4>Todo</h4>
<ul>
<li>Add variable for sample rate so that this could run randomly on production installs</li>
<li>Admin panel per site</li>
<li>Admin panel globally</li>
<li>WordPress error logging</li>
<li>Mysql query logging</li>
<li>WP_Error integration</li>
<li>Alerts ex: if this takes more than this much memory then log it…</li>
</ul>
