WP-Memory-Usage is a lightweight but powerful WordPress plugin that monitors and displays memory usage directly in your WordPress admin area. 
It is essential for site administrators and developers who need to keep an eye on memory consumption, identify bottlenecks, and act before users are affected.
What the plugin shows:
In the admin footer (every admin page): 
* Current memory usage vs. WordPress limit (with percentage) 
* Current memory usage vs. PHP limit (with percentage) 
* Server IP address and server name 
* PHP version
In the Dashboard widget (“Memory Overview”): 
* PHP version, architecture (32/64 bit), max execution time 
* WordPress memory limit (WP_MEMORY_LIMIT), WordPress admin limit (WP_MAX_MEMORY_LIMIT), PHP memory limit 
* Current peak memory usage with a visual progress bar (colour-coded: green / orange / red) 
* Latest digest status summary (warn / danger / critical badges) 
* Link to the Threshold Alerts settings page
Settings & Monitor — Tabs (since 2.0.0):
<ul>
<li>Settings — thresholds, logging options, email alerts, log rotation</li>
<li>History — latest logged requests with full context (URL, type, user, memory)</li>
<li>Digest — aggregated summaries of past log intervals; browse, merge, and delete digest files</li>
<li>️Actions — practical guidance on what to do when you receive a memory alert</li>
<li>Diagnose (new in 2.1.0) — full PHP/WordPress configuration snapshot with a ready-to-paste AI prompt for analysis</li>
<li>Memory Thresholds — current limits, threshold assessment, and recommendations</li>
<li>Check Installation — verifies that the plugin can run correctly on your server</li>
</ul>
<h3>Why Use WP-Memory-Usage?</h3>
Excessive memory usage leads to slower sites, HTTP 500 errors, and failed background jobs (cron, imports, backups). WP-Memory-Usage gives you the information you need to act before users are affected — without overwhelming you with notifications.
<h3>Features</h3>
<ul>
<li>Real-time memory display in the dashboard widget and every admin page footer</li>
<li>Colour-coded progress bar (green / orange / red) for instant status recognition</li>
<li>Three alert levels: Warning, Danger, Critical — each configurable as a percentage of the effective memory limit</li>
<li>Flexible logging: Ajax, REST, Admin, Cron, favicon requests — log only what matters</li>
<li>Email alerts with configurable recipient</li>
<li>History tab: recent requests with full context (URL, type, admin screen, REST route, AJAX action, user)</li>
<li>Digest tab: aggregated interval reports — browse, merge, and delete digest files</li>
<li>Actions tab: plain-language guidance on resolving memory alerts, no developer skills required</li>
<li>Diagnose tab (new in 2.1.0): full configuration snapshot + one-click AI prompt (English, copy & paste ready)</li>
<li>Memory Thresholds tab: shows effective limits, threshold gaps, and concrete recommendations</li>
<li>Check Installation tab: verifies log directory, WP-Cron, PHP functions, disk space, and email setup</li>
<li>Admin bar indicator: quick status badge visible on every admin page</li>
<li>Multisite compatible</li>
<li>Clean uninstall: removes all options, cron jobs, database-tables and log files on deletion</li>
</ul>

WP-Memory-Usage

Monitor PHP memory usage, set alert thresholds, and diagnose your server configuration — directly inside WordPress admin.

UsageDD allows administrators to monitor the resource usage of their WordPress installation. It will add a small box at the bottom center of each page, only visible to administrators, that displays the number of MySQL queries, the amount of memory used by the page’s code, and if you are using a compatible webserver (most are compatible), the “time to first byte” (TTFB) and the time required to generate the full page. TTFB is used by Google for page-ranking purposes, and it will be the first of the two displayed.
You can use the display to determine if your site has too many plugins loaded, if your theme is too “heavy”, or if something is wrong on your server. The plugin itself uses virtually no resources and should be compatible with every theme and plugin that outputs HTML.
Support is available in our <a href="https://forum.dion-designs.com/f35/usagedd-support/" rel="nofollow ugc">dedicated support area</a>. Support questions posted on wordpress.org may go unanswered for an extended period of time.
