What metric is affected when user tracking is turned off in Dynatrace Real user monitoring?

When user tracking is turned off in Dynatrace's Real User Monitoring (RUM), the metric that is most affected is the Returning vs. New User monitoring metric. This is because user tracking relies on the ability to distinguish between unique users who are accessing the application, allowing Dynatrace to classify users as either returning or new based on their interaction history.

When user tracking is disabled, Dynatrace cannot effectively differentiate between returning and new users since it cannot collect the necessary data that ties unique user sessions together. As a result, metrics that depend on this classification will lose accuracy. User feedback ratings, user interface load times, and application resource consumption metrics do not rely on the same level of user tracking detail to function, which means they will not be as directly impacted by turning off user tracking.
