implementing-real-user-monitoring

## Overview This skill streamlines the process of setting up Real User Monitoring (RUM) for web applications. It guides you through the essential steps of choosing a platform, defining metrics, and implementing the tracking code to capture valuable user experience data. ## How It Works 1. **Platform Selection**: Helps you consider available RUM platforms (e.g., Google Analytics, Datadog RUM, New Relic). 2. **Instrumentation Design**: Guides you in defining the key performance metrics to track, including Core Web Vitals and custom events. 3. **Tracking Code Implementation**: Assists in implementing the necessary JavaScript code to collect and transmit performance data. ## When to Use This Skill This skill activates when you need to: - Implement Real User Monitoring on a website or web application. - Track Core Web Vitals (LCP, FID, CLS) to improve user experience. - Monitor page load times (FCP, TTI, TTFB) for performance optimization. ## Examples ### Example 1: Setting up RUM for a new website User request: "setup RUM for my new website" The skill will: 1. Guide the user through selecting a RUM platform. 2. Provide code snippets for implementing basic tracking. ### Example 2: Tracking custom performance metrics User request: "I want to track how long it takes users to complete a purchase" The skill will: 1. Help define a custom performance metric for purchase completion time. 2. Generate JavaScript code to track the metric. ## Best Practices - **Privacy Complian...
