System events reference

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.
