Dynatrace Synthetic Monitoring provides a proactive approach to monitoring the availability and performance baselines of both public and internal web applications and API endpoints from diverse locations worldwide. By simulating user interactions in a controlled environment, it helps detect issues preemptively and allows for performance comparisons across deployments. The platform's recent updates include new web performance metrics focusing on paint times, which are crucial for assessing perceived load speeds and enhancing user experience. These metrics, such as First Paint, First Contentful Paint, and Largest Contentful Paint, align with Google's Core Web Vitals, providing a benchmark for optimization. Additionally, improvements to the Visually Complete calculation have been made, refining the accuracy for XHR actions and enabling more nuanced control over performance thresholds. Users can validate synthetic results against real user data, ensuring that improvements are effective across diverse real-world conditions. Further enhancements include easier management of synthetic credentials and support for various authentication methods, alongside the capability to monitor non-HTTP infrastructure components.
