What must be enabled in order to collect logs from non-Fortigate devices?

To collect logs from non-Fortigate devices, ADOMs (Administratively Domain) must be enabled. ADOMs are essentially a feature within FortiAnalyzer that allows for organizing and managing logs from various devices, including non-Fortigate devices. By using ADOMs, administrators can create separate logical domains to handle distinct sets of logs, enabling enhanced management, reporting, and analysis for different devices under a single FortiAnalyzer instance.

The other options do not facilitate log collection from non-Fortigate devices. Traffic logs and event logs specifically pertain to the activity and occurrences recorded by Fortigate devices. Archiving refers to the process of storing logs for long-term retention, but it doesn't inherently enable the collection of logs from devices that do not belong to the Fortigate family. Thus, enabling ADOMs is crucial to integrating logs from various non-Fortigate sources into the FortiAnalyzer system.
