Which setting adjustments may be required for XHR actions?

Enabling timed actions support is vital for accurately tracking and measuring the performance of XHR (XMLHttpRequest) actions within an application. XHR actions are often used to asynchronously request data from a server without having to reload the entire page. By enabling timed actions support, Dynatrace can effectively capture the timing data associated with these network requests, allowing for performance analysis and ensuring that slow transactions or requests can be identified and addressed.

This setting specifically allows Dynatrace to monitor how long these XHR requests take to complete, including any delays that may occur, which is essential for diagnosing performance issues related to asynchronous data fetching. It also helps in understanding the overall user experience, as slow XHR actions can significantly impact the perceived performance of an application.

Other adjustments, such as disabling error capturing, increasing buffering limits, or adjusting logging levels, may not directly relate to the specific measurement and performance assessment of XHR actions, which makes enabling timed actions support the most relevant and necessary adjustment in this scenario.
