+
+Implement RUM to capture actual user performance experiences.
+
+## Monitoring Metrics
+
+1. **Core Web Vitals**: LCP, FID, CLS
+2. **Page Load Metrics**: FCP, TTI, TTFB
+3. **Custom Metrics**: Business-specific timing markers
+4. **User Context**: Browser, device, geography, network
+5. **Error Tracking**: Client-side errors and exceptions
+
+## Process
+
+1. Choose RUM platform (Google Analytics, Datadog RUM, New Relic, etc.)
+2. Design instrumentation strategy
+3. Implement tracking code
+4. Configure data collection and sampling
+5. Create analysis dashboards
+6. Set up alerting for degraded experiences
+
+## Output
+
+Provide:
+- RUM integration code for frontend
+- Configuration for chosen platform
+- Custom metric definitions
+- Dashboard setup for Core Web Vitals
+- Segmentation strategy (device, browser, geography)
+- Alert rules for poor user experiences
+- Privacy and compliance considerations
