New Relic Synthetics Monitoring is a tool that allows developers to simulate user behavior on websites using Selenium and monitor web application performance in real-time. It provides detailed insights into how web applications perform from various locations around the world, by collecting data points such as load times, failures, and HTTP status codes every minute or at specified intervals. The goal of Synthetics Monitoring is to catch problems before customers do. It offers a range of monitoring dashboard sections, including an overview page that shows trends for load time, availability, slowest results, and failures, as well as detailed statistics for each page resource. Developers can configure and develop Selenium scripts to build complex monitoring workflows, and use the tool to troubleshoot issues and improve website performance. New Relic Synthetics Monitoring helps ensure web services are in place and working correctly by running automated tests on a set schedule.
