FortiAnalyzer Federation
FortiAnalyzer can also join a FortiAnalyzer Federation which enables centralized viewing of devices, incidents, and events across multiple FortiAnalyzers acting as members.
In this mode, FortiAnalyzer Federation members form a Fabric with one device operating in supervisor mode as the root device. Incident and event information is synced from members to the supervisor using the API.
See the FortiAnalyzer Federation Deployment Guide on the Fortinet Docs Library for more information.
