Which of the following interaction types is NOT detected by Real User Monitoring?

In the context of Real User Monitoring (RUM), the detection of various interaction types is crucial for understanding user behavior on web applications. The correct answer indicates that "Mouse over" is not typically tracked by RUM.

RUM focuses on capturing meaningful interactions that indicate user engagement with a website. Clicks, touch starts, and key downs represent direct user actions that typically lead to significant events, such as navigation or input submission. These interactions provide valuable insights into user intent and behavior, making them essential metrics for performance and usability analysis.

While a "Mouse over" interaction can be indicative of user interest, it does not usually indicate a definitive action or intention to engage with the website further. Therefore, it is often not prioritized for tracking in RUM, as it may introduce noise into the data without providing actionable insights. Consequently, the focus remains on interactions that signify clear user actions that can substantially impact user experience and site performance.
