The New Relic Netlify Plugin simplifies monitoring Jamstack application performance with real-user monitoring (RUM) and provides critical insights into site performance metrics in production. The plugin automates the installation of the browser monitoring agent, notifies New Relic One when a build event occurs in Netlify, and measures site performance using Google Core Web Vitals. It also allows developers to quickly discover and fix errors before they impact users, explore data using custom-built dashboards, and receive notifications when there are issues with their Netlify site. The plugin can be easily installed via the Netlify UI, by creating environment variables, or by adding a configuration block to the netlify.toml file. Additionally, developers can customize alerts for performance in New Relic One and explore additional features and configuration options in the plugin documentation.
