Enhancing Performance Troubleshooting: Connecting Core Web Vitals with Session Replays

In today’s digital world, improving website performance is a top priority for developers and product managers, but identifying the root cause of issues can still be challenging and time consuming, with teams teams spending considerable time trying to understand why a website had a slow Largest Contentful Paint (LCP) or a high Interaction to Next Paint (INP). New Relic continues to invest in ways to make this easier and more streamlined by directly connecting Core Web Vitals (CWV) with Session Replays. This integration provides additional context by displaying key performance metrics like Largest Contentful Paint (LCP) and Interaction to Next Paint (INP) directly on the replay timeline, allowing developers to see exactly when and where performance bottlenecks occur during a user's session and correlate them with user frustration, moving beyond manual guesswork and log-sifting to seeing exactly what the user experiences to troubleshoot faster.

Getting  to the Root Cause faster

The new integration simplifies this by adding a Session Replays column to CWV dashboards. This allows you to see the number of session replays associated with specific performance issues across various dimensions like geography, device type, or page URL. By clicking on the number of available session replays, you're taken to a pre-filtered list of user sessions that are directly affected by the performance problem. The system intelligently prioritizes sessions with the most critical CWV issues, giving you a clear starting point for investigation. This workflow offers several key benefits:

• Find root cause faster: Quickly pinpoint the source of performance issues and resolve them to keep your users engaged.
• Prioritize customer impacting issues: Fix what matters most to users to improve digital experiences and reduce churn.
• See it, fix it for good: Watch actual user sessions to understand the impact of performance problems to create better overall user experiences.

This feature is available to all New Relic users who have both Browser entity instrumentation and Session Replays enabled. If you need more data, you can simply increase your sampling rate in the Browser Application settings. This update continues to build on delivering better user experiences by speeding up root cause and resolutions and making it easier to resolve customer issues.  Learn more here.
