Rayetun Site Monitor
Rayetun Site Monitor
Description
Stop guessing about your site’s performance. Rayetun Site Monitor gives you real-user Core Web Vitals data collected directly from your visitors’ browsers — no external account, no API key, no tracking from third parties.
Activate it. Visit a few pages. Within seconds you’ll see live performance metrics on your WordPress dashboard.
⚡ Why This Plugin?
Unlike Search Console (which shows aggregated, delayed data), Rayetun Site Monitors every page in real-time from the moment of activation. No sample-size thresholds. No waiting for Google to collect data. Just instant, actionable insights.
- 🎯 Zero configuration — activate and data flows immediately
- 📊 Real users, real data — field metrics from actual visitors (not synthetic robots)
- 🔒 Your data stays yours — everything lives in your WordPress database
- ⚡ No impact on performance — sub-4KB beacon, loaded with defer, zero blocking
- 🔐 GDPR-friendly — no cookies, no third-party data sharing
📈 What It Measures
The plugin tracks all five Core Web Vitals and presents them with Google’s official thresholds:
Metric
Target
What It Means
LCP — Largest Contentful Paint
≤ 2.5s
How fast your main content appears
CLS — Cumulative Layout Shift
≤ 0.1
How stable your page layout stays
INP — Interaction to Next Paint
≤ 200ms
How responsive your site feels to clicks
FCP — First Contentful Paint
≤ 1.8s
How fast anything appears on screen
TTFB — Time to First Byte
≤ 800ms
How quick your server responds
🖥️ The Dashboard
A single glance tells you everything about your site’s performance:
- Score cards — P75 value per metric with color-coded Good / Needs Improvement / Poor badges
- Distribution bars — see at a glance what % of page loads fall into each rating band
- Sparkline trend charts — watch how each metric improves (or worsens) over 7, 14, or 30 days
- Slowest Pages ranking — which URLs need the most work, sorted by LCP
- Device split — toggle between All Devices, Mobile Only, or Desktop Only
- Date range & URL filters — drill into specific time periods and individual pages
🔍 LCP Element Attribution
“My LCP is slow. But what is slow?”
Rayetun Site Monitor answers that automatically. The beacon captures the exact DOM element responsible for Largest Contentful Paint — whether it’s a hero image, a video embed, a heading, or a background. See the element tag, CSS class, and image source right alongside the metric.
No guesswork. No DevTools digging. Just answers.
🧪 PageSpeed Insights Lab Tests
Click PSI on any page row and Google’s lab test runs instantly inside your WordPress admin. Compare your real-user data (Field LCP P75) with Google’s synthetic lab test in a single view:
- Lab performance score
- Lab metrics: LCP, FCP, CLS, TBT
- Field LCP P75 (real-user percentile)
- Failed Opportunities list (unused JS, render-blocking resources, unoptimized images)
- One-hour result caching to stay under API limits
No plugin configuration needed — the plugin works without an API key. Add a free key to get 25,000 requests/day instead of 25.

External Services
This plugin contacts external services only when explicitly triggered by an admin action or through an opt-in configuration. No data is transmitted automatically in the background.
🔬 Google PageSpeed Insights API
Triggered by: Clicking the PSI button on a page row (manual, admin-only action)
Data sent: The page URL being tested (e.g., https://example.com/my-page/). No visitor data, no personal information.
Recipient: Google LLC
Endpoints:
– https://www.googleapis.com/pagespeedonline/v5/runPagespeed — API endpoint
– https://pagespeed.web.dev/ — report viewer (browser link only, no plugin data sent)
Privacy: Google Privacy Policy | Terms of Service
📚 Google web.dev Documentation Links
The WordPress Site Health integration displays links to Google’s public Core Web Vitals documentation. These are standard hyperlinks that open in a browser tab — the plugin sends no HTTP requests to these URLs.
https://web.dev/articles/lcp/https://web.dev/articles/cls/https://web.dev/articles/inp/https://web.dev/articles/fcp/https://web.dev/articles/ttfb/
🔔 Webhook Notifications (opt-in)
Triggered by: Site admin enabling the feature and configuring a URL in Settings Webhook Notifications, and a performance threshold being exceeded
Data sent: Site name, site URL, metric name, P75 value, threshold, and the page URL that triggered the alert. No visitor data.
Recipient: The URL configured by the site admin (Slack workspace, Discord server, Zapier account, custom server, etc.). The plugin author has no access to webhook destinations.
🏠 Front-end Beacon (your site only)
The JavaScript beacon collects performance data only from your own site’s REST API at /wp-json/rayetun-site-monitor/v1/collect. Zero data is sent to external servers. Visitor metrics stay on your server.

Faq
The plugin collects metrics from real visitors. Open a few pages on your site in a web browser after activation, then refresh the dashboard. You’ll see data within seconds of each page view.
No. The beacon loads with the defer attribute (non-blocking) and is under 4 KB. It uses the browser’s native PerformanceObserver API — no external library downloads, no render-blocking scripts. Your page speed is unaffected.
Search Console shows aggregated, multi-day-old data that requires a minimum sample size before displaying. Rayetun shows data from the moment of activation for every individual page, broken down by device, with real-time threshold alerts and PSI lab tests triggered on-demand.
Data older than 30 days is automatically purged by a daily WordPress cron job. This keeps your database lean with zero manual cleanup.
Yes. The JavaScript beacon runs in the visitor’s browser after page load completes, regardless of server-side caching.
Click PSI on any row in the Slowest Pages table or the Posts/Pages list column. The PSI API works without a key. To avoid Google’s anonymous rate limits on high-traffic sites, get a free API key at developers.google.com and paste it into Site Monitor Settings.
Go to Site Monitor Settings Webhook Notifications, toggle it on, and paste your endpoint URL. For Slack, use an Incoming Webhook URL. For Discord, append /slack to the webhook URL. Alerts fire only when a configured threshold is exceeded.
Yes. The Export CSV button downloads up to 50,000 rows for your selected date range and device filter. The file opens directly in Excel, Google Sheets, or any BI tool.
Currently designed for single-site installs. Multisite support is on the roadmap for a future release.
No. Rayetun Site Monitor is completely standalone — it doesn’t read, modify, or interfere with any other plugin’s data.
The plugin is built on WordPress standards (REST API, WP-Cron, options API) and works with any properly configured WordPress site. It’s been tested on WordPress 6.2+ with PHP 8.0+.
