JRMora

This plugin adds a native widget to the WordPress dashboard that connects to your Matomo On-Premise installation to display vital metrics in real-time.
Unlike other plugins that use iframes (often blocked for security) or synchronous PHP requests (which slow down the admin area), this widget uses a 100% JavaScript (Client-Side) architecture.
Your WordPress server performs no requests; the browser queries your Matomo API directly.
Key Features:
<ul>
<li>Zero Server Impact: All processing is done in the client’s browser.</li>
<li>Pure Real-Time: Visitor counters and logs update automatically every 10 seconds.</li>
<li>Smart Hybrid Chart: Combines historical data (cached) with real-time data from the current day for total accuracy.</li>
<li>Performance Monitor: Detailed chart of load times (Network, Server, DOM…) and visit duration metrics.</li>
<li>“Black Box” Tooltips: Detailed, accessible information on hover, with visual differentiation for Searches, Downloads, Outlinks, and Events.</li>
<li>Privacy-Friendly: IP masking and visitor ID hashing included.</li>
<li>Native Notifications: Desktop alerts and optional sound when new visits arrive or traffic thresholds are met.</li>
</ul>

This is a unofficial, basic WordPress plugin for the Matomo web analytics software platform. 
It adds the Matomo javascript code into every page of your website, so you don’t have to code PHP to add it to your templates.
It is based quite heavily on the (no more supported) Piwik Analytics WordPress plugin which itself is based on the (no more available) Google Analytics wordpress plugin by Joost de Valk.
The following options are supported:
<ul>
<li>matomo hostname</li>
<li>matomo path</li>
<li>site ID</li>
<li>option to control download tracking</li>
<li>option to exclude the admin user (probably you)</li>
</ul>
Please note, this plugin requires a self-contained Matomo installation somewhere under your control. It does not include Matomo itself.
