What information is typically contained in System Pages?

System Pages in Pega are designed to hold specific information about the current state of the application and context in which it operates. One of the primary purposes of System Pages is to provide details about the current user session, which includes aspects like user roles, access rights, and session-specific data. This information is vital for managing user interactions and ensuring that the application behaves appropriately based on the logged-in user's status and permissions.

The other options do not align with the primary function of System Pages. Data about inactive users, for example, would not be relevant to a current session and typically doesn't reside within System Pages. Similarly, while system resource usage is important for overall application performance, it is not typically stored in the context of user sessions in System Pages. Cached requests made to external systems may affect how an application interacts with external services but do not relate directly to the current user context maintained in System Pages. Thus, focusing on the current user session is what makes this option the most relevant.
