How long is RUM data stored for waterfall analysis?

1. 5 days

2. 10 days

3. 30 days

4. 7 days

The correct answer is: 10 days

RUM (Real User Monitoring) data is stored for waterfall analysis for 10 days. This specific retention period allows users to analyze the performance of web pages over the past week and a half, providing a comprehensive view of user interactions and experience. The waterfall analysis is vital for diagnosing issues related to page load times and identifying specific bottlenecks in resource loading, which can be pivotal for optimizing web performance. This 10-day data retention is standardized within Dynatrace to ensure that businesses can historically compare and analyze user experiences over a reasonable timeframe. This duration strikes a balance between offering sufficient historical data for trend analysis and managing storage resources effectively. In terms of other durations mentioned, shorter periods such as 5 days or 7 days would not provide enough historical context for effective analysis, while a duration of 30 days extends beyond the standard practice for RUM data retention in Dynatrace.
