To provide a comprehensive report of system usage, the most important elements are user identifications (IDs) and access timestamps. These data points record who accessed the system, at what time, and for how long. Together, they allow the analyst to determine frequency and duration of use, which is essential for both operational auditing and security oversight.

Other options, such as informational logs or error logs, may provide context but do not directly answer the requirement of identifying users and usage patterns. For instance, 802.1x logs are related to network authentication, while commands or error timestamps reveal activity details but not the overall access history.

Collecting and analyzing IDs and timestamps supports compliance with regulatory frameworks like ISO 27001 and SOC 2, which require clear audit trails. It also provides accountability and supports investigations in case of unauthorized access or misuse. By including these elements, the analyst ensures the report meets internal and external requirements for system monitoring.
