Title: WP-Memory-Usage Author: berkux Published: June 13, 2009 Last modified: May 25, 2026 --- Search plugins ![](https://ps.w.org/wp-memory-usage/assets/banner-772x250.png?rev=3474934) ![](https://ps.w.org/wp-memory-usage/assets/icon-256x256.png?rev=3474934) # WP-Memory-Usage By [berkux](https://profiles.wordpress.org/berkux/) [Download](https://downloads.wordpress.org/plugin/wp-memory-usage.2.3.0.zip) * [Details](https://tzm.wordpress.org/plugins/wp-memory-usage/#description) * [Reviews](https://tzm.wordpress.org/plugins/wp-memory-usage/#reviews) * [Development](https://tzm.wordpress.org/plugins/wp-memory-usage/#developers) [Support](https://wordpress.org/support/plugin/wp-memory-usage/) ## Description 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):** * **Settings** — thresholds, logging options, email alerts, log rotation * **History** — latest logged requests with full context (URL, type, user, memory) * **Digest** — aggregated summaries of past log intervals; browse, merge, and delete digest files * **️Actions** — practical guidance on what to do when you receive a memory alert * **Diagnose** _(new in 2.1.0)_ — full PHP/WordPress configuration snapshot with a ready-to-paste AI prompt for analysis * **Memory Thresholds** — current limits, threshold assessment, and recommendations * **Check Installation** — verifies that the plugin can run correctly on your server ### Why Use WP-Memory-Usage? 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. ### Features * **Real-time memory display** in the dashboard widget and every admin page footer * **Colour-coded progress bar** (green / orange / red) for instant status recognition * **Three alert levels:** Warning, Danger, Critical — each configurable as a percentage of the effective memory limit * **Flexible logging:** Ajax, REST, Admin, Cron, favicon requests — log only what matters * **Email alerts** with configurable recipient * **History tab:** recent requests with full context (URL, type, admin screen, REST route, AJAX action, user) * **Digest tab:** aggregated interval reports — browse, merge, and delete digest files * **Actions tab:** plain-language guidance on resolving memory alerts, no developer skills required * **Diagnose tab** _(new in 2.1.0)_: full configuration snapshot + one-click AI prompt (English, copy & paste ready) * **Memory Thresholds tab:** shows effective limits, threshold gaps, and concrete recommendations * **Check Installation tab:** verifies log directory, WP-Cron, PHP functions, disk space, and email setup * **Admin bar indicator:** quick status badge visible on every admin page * **Multisite compatible** * **Clean uninstall:** removes all options, cron jobs, database-tables and log files on deletion ### PluginCheck-Plugin Status Plugin is compatible with PluginCheck-Plugin. Note regarding “trademarked_term”:“ WP-Memory-Usage” and “wp-memory-usage” are today considered restricted terms. This plugin entered the WordPress repository in 2009, when those terms were permitted. ### Credits Copyright 2009–2013 by Alex Rabe, 2022– Bernhard Kux ## Screenshots * [[ * Dashboard widget – Memory Overview with progress bar and latest digest status badges (warn / danger / critical) * [[ * Settings tab – thresholds, logging options, email alert configuration * [[ * History tab – recent requests with context (URL, type, memory usage) * [[ * Digest tab – aggregated interval summaries * [[ * Diagnose tab – PHP/WordPress configuration snapshot with AI prompt (new in 2.1.0) * [[ * Memory Thresholds tab – effective limits, assessment and recommendations * [[ * Check Installation tab – server compatibility checks ## FAQ ### Where is the memory usage displayed? In three places: the WordPress dashboard widget “Memory Overview”, the admin footer on every backend page, and in detail across the plugin’s settings tabs. ### What information does the plugin display? PHP version, operating system architecture, WordPress and PHP memory limits, current peak memory usage (in MB and as a percentage), server IP address, and PHP max execution time. ### How can I find out which request consumes the most memory? Enable logging in the Settings tab. The History tab shows individual requests with their memory usage and context. The Digest tab aggregates this data and highlights the top memory-consuming URLs. Temporarily deactivating plugins is a common next step to isolate the cause. ### What is the Diagnose tab? The Diagnose tab (new in 2.1.0) collects a comprehensive snapshot of your PHP and WordPress memory configuration — OPcache status, garbage collector, loaded extensions, php.ini settings, and more. It generates a ready-made prompt you can copy and paste directly into an AI assistant (ChatGPT, Claude, etc.) for instant analysis. ### Does the plugin work with WordPress Multisite? Yes. ### What happens when I delete the plugin? A clean uninstall removes all stored options, scheduled cron jobs, database-tables, and log files. Nothing is left behind. ## Reviews ![](https://secure.gravatar.com/avatar/00c17b22f5d8876e78f6f8efc935495d58ad8bd5b115d73ec0d5f61213c87953? s=60&d=retro&r=g) ### 󠀁[Helped fix site performance problems](https://wordpress.org/support/topic/helped-fix-site-performance-problems/)󠁿 [scmsteve](https://profiles.wordpress.org/scmsteve/) March 24, 2026 I originally found this becuase I was trying to monitor memory usage to help diagnose poor site performance. It works well for that. However, it also has a tab with a lot of other statistics and it was some of these that helped me track down some opcache issues. Site load times went from TTFB of about 2.25s to 0.6s after tuning! I am very thankful for this plugin, you should give it a try if you are trying to get some very useful stats. The inclusion of an AI prompt is also very nice as it might help you figure out what the numbers are telling you. ![](https://secure.gravatar.com/avatar/fff0c98ff4d4a93b60303319da74d158898e262d694144992f1bcba2cc2d2ad0? s=60&d=retro&r=g) ### 󠀁[Displays the memory limit & current memory usage](https://wordpress.org/support/topic/displays-the-memory-limit/)󠁿 [Denny Müller](https://profiles.wordpress.org/redaquamedia/) March 26, 2024 Minimal, clear and useful.
