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 Compliance: Ensure compliance with privacy regulations (e.g., GDPR, CCPA) when collecting user data.
• Sampling: Implement sampling to reduce data volume and impact on performance.
• Error Handling: Implement robust error handling to prevent tracking code from breaking the website.

Integration

This skill can be used in conjunction with other monitoring and analytics tools to provide a comprehensive view of application performance.
