MUDRAVA

<p>MUDRAVA RUM captures real user performance data from your WordPress site visitors. Unlike synthetic testing tools, this plugin measures actual user experience including Time to First Byte (TTFB), Largest Contentful Paint (LCP), server generation time, total page load time, and more.</p>
<p><strong>Features:</strong></p>
<ul>
<li>Collects TTFB, LCP, server generation time, total load, memory peak, device type, network type, country, and session ID</li>
<li>Live Monitor dashboard with real-time log viewing</li>
<li>Filterable by session ID, URL, device type, and network type</li>
<li>On-demand performance reports with averages and P75 LCP</li>
<li>Scheduled email summaries (daily or weekly via WP-Cron)</li>
<li>Critical TTFB alerts with configurable thresholds</li>
<li>Configurable sampling rate and URL blacklist</li>
<li>Role-based exclusion (skip tracking for specific user roles)</li>
<li>Automatic data retention management (max records and days)</li>
<li>Color-coded performance indicators (good/warning/poor)</li>
</ul>
<p><strong>How It Works:</strong></p>
<p>A lightweight JavaScript collector runs on your site’s frontend, gathering Core Web Vitals and performance metrics from each page view. Data is sent via the WordPress REST API and stored in a custom database table. The admin dashboard provides a Live Monitor view, filterable reports, and email summaries.</p>
