Type of the event.
An event is created every time an associated rule or geofence is triggered by a device ingestion.
The event type depends on the data the device sends.
Sensors that report numerical data (such as battery, humidity, pressure and temperature sensors),
generate an event when the reported sensor reading of the device goes in or out of range, which is configured in the rule.
This produces events of BELOW_RANGE, IN_RANGE and ABOVE_RANGE types.
Sensors that report boolean data (such as attach and tamper sensors), generate events when the device
transitions from one state to another, either from false to true or vice versa.
This produces events of FALSE_TO_TRUE and TRUE_TO_FALSE types.
The same event types are also generated by the online rule when the device state changes from offline
(when the device has stopped ingesting data) to online (when the device data ingestion has resumed)
or vice versa.
The acceleration sensor generates events whenever the reported sensor reading
crosses the acceleration threshold (for example, when the device was dropped).
This produces events of the type EVENT.
Such events are stateless.
Events of INSIDE_GEOFENCE and OUTSIDE_GEOFENCE types are generated when the device enters or exits
a geofence associated with the device.
Events of DWELLING_STARTED type are generated when the device has
stayed inside an associated geofence for longer than the threshold duration.
DWELLING_ENDED type events are generated when dwelling of the device has ended.
Events of DETENTION_STARTED type are generated when the device has been
stationary for longer than the threshold duration, regardless whether the device is inside
or outside of any geofence.
DETENTION_ENDED type events will be generated when the device starts moving again.
Events of UNUTILIZED type are generated when the device has been stationary for longer than the
threshold duration.
UTILIZED type events are generated when the device starts moving again after having been stationary.
Events of OVERSTOCK, NORMAL_VOLUME and UNDERSTOCK types are generated when the number of assets
inside a geofence crosses the minVolume and maxVolume thresholds of an associated stock rule.
Events of SHIPMENT_EARLY, SHIPMENT_ON_TIME and SHIPMENT_DELAYED types are generated when a shipment
is too early, on time or delayed.
