What function does the report calendar serve?

The report calendar serves the crucial function of providing an overview of all scheduled reports. This feature allows users to easily see what reports have been planned, their timings, and their frequency. Having a centralized view helps in managing reporting activities effectively, ensuring that all stakeholders are aware of when reports are generated. This overview is especially beneficial in operational environments where timely access to data is important for decision-making processes.

The other options relate to different functionalities that are handled by FortiAnalyzer or similar reporting systems. Scheduling future reports pertains to a more specific task of setting dates and times for report generation. Generating real-time reports involves the immediate creation of reports based on current data, which is a separate capability. Meanwhile, managing report templates relates to the design aspect of reports, which is not the primary focus of the report calendar. Thus, option B specifically highlights the calendar's role in managing and overseeing scheduled reporting activities.
