See what your users actually experience.
Core Web Vitals, real user sessions, JavaScript errors, and frontend performance — captured from real browsers, not synthetic probes.
Your servers are healthy. Your users are not.
Server metrics look fine. Uptime is 100%. But users are complaining about slow page loads, broken buttons, and invisible errors. Without RUM, the frontend is a black box — you see what your infrastructure reports, not what your users experience.
Everything Real User Monitoring captures.
Real signals collected by the Watchlog Agent — available in your dashboard within 60 seconds of enabling.
Web Vitals — by page, device, and region.
Your frontend performance scored and segmented the way Google PageSpeed measures it.
| Page | Avg Load | LCP | Errors |
|---|---|---|---|
| /checkout | 2.1s | 1.8s | 3 |
| /dashboard | 1.4s | 1.2s | 0 |
| /login | 0.9s | 0.8s | 0 |
| /products | 3.2s | 2.9s | 7 |
What Real User Monitoring gives you.
How engineering teams use Real User Monitoring.
A deploy degraded LCP on /checkout from 1.2s to 4.8s. RUM shows the regression, the affected users, and the slow resource.
An exception is throwing on 8% of checkout sessions. RUM shows the error, stack trace, and session replay so you can reproduce it.
Web Vitals segmented by device show mobile users have 3x worse LCP. RUM pinpoints the heavy resource causing it.
RUM surfaces sessions where users rage-clicked a button 6 times. Replay shows the button is unresponsive due to a JS error.
Real User Monitoring inside the Watchlog platform.
RUM pairs with Synthetic Testing for proactive vs. reactive frontend visibility, APM for trace correlation on slow API calls, and Alerts for Web Vitals threshold notifications.
Start Real User Monitoring in under 2 minutes.
No YAML. No complex configuration. The Watchlog Agent handles discovery automatically.
Install the Watchlog RUM SDK for your frontend framework. For Vue.js, use @watchlog/rum-vue.
npm install @watchlog/rum-vueSign in to Watchlog, open the RUM page, and copy your API Key and endpoint from app.watchlog.io/rum.
https://app.watchlog.io/rumAdd the Watchlog RUM plugin to your frontend entry file and pass the API Key, endpoint, app name, and router.
app.use(createWatchlogRUMPlugin({
router,
apiKey: 'YOUR_API_KEY',
endpoint: 'https://api.watchlog.io/rum',
app: 'my-vue-app',
environment: 'production'
