Which logging option is specifically CLI only when configuring logging in FortiGate?

The logging option that is specifically CLI only when configuring logging in FortiGate is the store-and-upload option. This functionality allows for logs to be stored locally on the FortiGate unit and then periodically uploaded to a central logging location. This approach is not available through the graphical user interface (GUI), making it unique in that it can only be set up through the command-line interface (CLI).

CLI-only options are typically intended for advanced configurations or those that require specific adjustments that GUI does not offer. The ability to manage log storage and upload through CLI can be especially beneficial for network administrators looking for flexibility and efficiency in log management, ensuring they can automate these tasks based on their network's needs.

Other choices, such as real-time logging, are available in both CLI and GUI, hence they do not have the same specificity regarding interface usage as the store-and-upload option. The timing-based logging options, such as “Every minute” and “Every 5 minutes,” also can be configured through the GUI, further differentiating them from the store-and-upload option in terms of accessibility and configuration method.
