Event codes and event types

Applications that handle event data can have a set of codes to identify the types of events that generated the event data. For example, event codes can identify whether an event was caused by a power outage or a possible tamper. These event codes are typically mapped to the event identifiers provided by other systems.

• The CEF v1.0 schema provides event code information in the EventType element. The IsHistorical element indicates whether the event is an alarm or historical event.
• The CEF v2.0 schema provides event code information in the EventCategory element. The EventType element indicates whether the event is an alarm or historical event.

Alarm events are sometimes called status events or current events.
