What types of errors does Dynatrace capture in Real User Monitoring (RUM)?

Dynatrace captures a comprehensive set of errors in Real User Monitoring (RUM), which includes JavaScript errors, HTTP errors, and failed resources. This multifaceted approach allows for a deeper understanding of how end users interact with applications and the issues they might encounter.

JavaScript errors are critical as they directly affect the functionality and user experience on web pages. Capturing these errors helps identify problems in the client-side scripts that may prevent parts of the application from functioning correctly.

HTTP errors are also essential for monitoring because they indicate issues with server responses to client requests. These errors can lead to failed loading of resources, pages, or features, significantly impacting user satisfaction.

Additionally, capturing failed resources is vital as it covers scenarios where specific assets, such as images, scripts, or stylesheets, fail to load. This type of error can degrade the visual and interactive quality of an application, leading to a poor user experience.

Together, these error types provide a holistic view of the application's performance from a user's perspective, allowing organizations to quickly identify and resolve problems that may hinder user engagement and satisfaction.
