Which of the following is NOT included in Real User Monitoring (RUM) data capture?

Real User Monitoring (RUM) focuses on capturing data about real users' interactions with a web application in order to analyze the user experience and performance. In the context of RUM data capture, key components tracked typically include user actions, session properties, and information such as IP addresses and geographical locations.

User actions refer to interactions such as clicks and navigation within the application, providing insight into how users engage with the interface. Session properties encompass metadata about the users' sessions, such as duration and page views. The collection of IP addresses and locations is significant for understanding the geographic distribution of users, which can influence performance and content delivery.

Method arguments, on the other hand, pertain to more technical details related to server-side processes or API calls, which are generally outside the scope of what RUM captures. RUM is more focused on front-end performance aspects from the user's perspective rather than backend processing details. As such, method arguments are not part of the data collected in Real User Monitoring, making this the correct answer.
