Which troubleshooting feature allows a user to analyze client performance over time?

Client Insights is the correct choice as it provides a comprehensive overview of client performance over time, enabling users to effectively analyze trends and behaviors. This feature aggregates various types of data, allowing users to see how clients interact with the network on a long-term basis. Through Client Insights, users can monitor metrics such as connection quality, throughput, and latency, helping to pinpoint performance issues and understand the overall client experience.

The other options serve different purposes. Historical Data Logs typically focus on storing records of previous events and activities rather than analyzing ongoing performance trends. Session Statistics provide real-time metrics regarding active sessions, which can be useful for immediate troubleshooting but do not extend to long-term analysis. Performance Alerts notify users of specific issues or thresholds being reached but do not offer a continuous view of client performance over time like Client Insights does.
