WP-Memory-Usage is a lightweight but powerful WordPress plugin that monitors and displays memory usage directly in your WordPress admin area. 
This tool is essential for site administrators and developers who need to keep an eye on the memory consumption of their WordPress installation, helping to identify potential issues and optimize performance.
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) 
* Link to the Threshold Alerts settings page
Memory Alerts Tabs (since 2.0.0): 
Log events, set thresholds (Warning / Danger / Critical), monitor memory usage…
<h3>Why Use WP-Memory-Usage?</h3>
