concept australia Updated Sep 10, 2026 1 min read system-events-reference.md
Reference topics provide information about system events.
- Event logs
The event log records all system events that occur within the ServiceNow AI Platform. - Event states
The event state describes where in the life cycle the event is. - The incident events business rule
The incident events business rule comes with the system and defines a number of events that can be triggered by different actions in the Incident table. - Global events
Your instance has a global function called global_events() that triggers from a business rule when certain conditions occur. - Script actions
You can use script actions to create server-side scripts that perform a variety of tasks, such as modifying a configuration item (CI), or managing failed login attempts. Script actions are triggered by events only. - Sample scripts from the change events business rule
Several scripts are found in the baseline change events business rule.
