# System Events

As described on the previous pages, the [Event Service](https://docs.extrahorizon.com/extrahorizon/services/automation/event-service) allows you to view and fire events and the [Dispatcher Service](https://docs.extrahorizon.com/extrahorizon/services/automation/dispatchers-service) allows you to subscribe to events and execute actions based on them.
