Which type of personal information is NOT captured by default in RUM?

In Real User Monitoring (RUM), the system captures various metadata about users to help analyze performance and user experience. However, user’s local time zone is typically not collected by default. This decision likely stems from privacy concerns, as capturing more granular personal information can pose risks related to data privacy regulations and user consent.

By default, systems prioritize capturing basic information needed for performance analysis, such as the user's IP address, browser version, and device type. This information is crucial for understanding how different environments affect the performance of web applications. In contrast, local time zone data is less critical for the types of performance analyses that RUM aims to perform, making it an optional piece of data that might require explicit consent or configuration to collect.

Thus, while other types of information are essential for technical assessment and troubleshooting, the local time zone is often omitted by default to ensure compliance with privacy regulations and to ask for explicit user consent before collection.
