WP-Memory-Usage vs Display PHP Version

Very lightweight and simple plugin that displays the currently installed PHP/MySQL version in the “At a Glance” admin dashboard widget. In the latest plugin version you can also view the current MySQL version when hovering over the PHP version text. We chose to implement it this way as you may not need to know the MySQL version as often as the PHP version, and it just adds unnecessary visual noise. Just hover over the PHP version label to display the installed MySQL version. Also, on some Windows based servers the returned MySQL version can be displayed with a 5.5.5- prefix which can be a little annoying, so this is removed for convenience. Please rate this Plugin if you find it useful. It only takes a moment but it’s very much appreciated. 🙂 And here’s how you can help support our open source work. We couldn’t do this without you!

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?
