AWS – Amazon CloudWatch RUM adds support for Interaction to Next Paint (INP) Web Vital

Today, CloudWatch RUM, a real-time monitoring service that visualizes and analyzes user interactions with web applications, announces support for Interaction to Next Paint (INP) web vital monitoring. This crucial metric would help customers measure the latency of a page’s response to user interactions, offering insights into the end-user experience of their web application.

INP is a metric that assesses a page’s overall responsiveness to user interactions by observing the latency of all click, tap, and keyboard interactions that occur throughout the lifespan of a user’s visit to a page. The final INP value is the longest interaction observed, ignoring outliers. This new metric joins the existing set of core web vitals tracked by CloudWatch RUM. The time series graph for INP allows customers to instantly assess whether page responsiveness is positive, tolerable, or frustrating based on a percentile aggregate of the metric. Furthermore, customers can click on specific data points to access a list of correlated INP events, leading them directly to affected user sessions for in-depth analysis of issues and their impact on user experience. Users can start capturing INP by upgrading the aws-rum-web to v1.23.0 at minimum, which is now available via NPM and CDN.

The new INP metric is available in all AWS Regions where CloudWatch RUM is available at no additional cost to customers.
