Default event views – FortiAnalyzer – FortiOS 6.2.3
Default event views
FortiAnalyzer event handlers apply one or more tags to events, allowing the events to be grouped into views in the Event Monitor. These views are visible in the left navigation tree. Default views are organized into three view categories, including:
- By Endpoint: Provides security event views from an endpoint perspective.
- By Threat: Provides security event views from a threat perspective. l System Events: Provides event views which cover device system events.
