What type of information is primarily extracted using the OneStream System Diagnostics solution?

The OneStream System Diagnostics solution is primarily utilized to gather application performance metrics. This includes detailed insights into how well the system is functioning, processing speeds, resource utilization, and potential bottlenecks that may affect performance. By focusing on application performance metrics, organizations can monitor the efficiency and effectiveness of their OneStream applications, enabling them to identify and resolve issues that may hamper the overall user experience or system reliability.

While financial summaries provide important data for reporting and analysis, they do not directly pertain to the performance of the application itself. Server hardware specifications are related to the physical resources but do not reflect how the application is operating or performing. Similarly, user access reports focus on the security and permissions within the system rather than its performance. Therefore, the emphasis on application performance metrics distinguishes this choice as the correct answer.
