Reference topics provide information about system events.
* **[Event logs](https://www.servicenow.com/docs/IuKEabFIzHx4vnq8~x9AhA)**   
  The event log records all system events that occur within the ServiceNow AI Platform.
* **[Event states](https://www.servicenow.com/docs/2AzRls6vTZc4CQoh9XKrtA)**   
  The event state describes where in the life cycle the event is.
* **[The incident events business rule](https://www.servicenow.com/docs/d0KFopmi2SCU79_oQSmLHg)**   
  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](https://www.servicenow.com/docs/hl29bQNPm9I3dCfLg0kTYw)**   
  Your instance has a global function called global_events() that triggers from a business rule when certain conditions occur.
* **[Script actions](https://www.servicenow.com/docs/YW9cd7rD82FUiMSqFdsT6Q)**   
  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](https://www.servicenow.com/docs/elXJZVjbnJJD_oKQc63ikg)**   
  Several scripts are found in the baseline change events business rule.
