What must the firewall administrator do to complete a Custom report showing bandwidth usage for the "mgt" group?

To complete a Custom report showing bandwidth usage for the "mgt" group, selecting 'Source User' from the 'Available Columns' is essential because it allows the report to display data specifically related to user activities within that group. By including this as a column in the report, the administrator can directly correlate bandwidth usage to individual users in the "mgt" group, providing granular visibility into how bandwidth is consumed by specific users or applications associated with them.

This is crucial for understanding bandwidth utilization patterns and for making informed decisions about resource allocation, policy adjustments, or additional training that may be required for users consuming excessive bandwidth. Selecting user details enhances the report's relevance, making it a powerful tool for network monitoring and analysis.
