<Description><![CDATA[Event Type is a readable and writable resource used to represent how this event will behave. Event Type should be one of the following values:-
0. Disabled
1. Alarm Current State
2. Alarm State Change Log
3. Event Log
When the Event Type is set to Disabled (0), this event will not be recorded by the device. No Latest Eventlog payload should be delivered for events that are Disabled.
When the Event Type is set to Alarm Current State (1), this Event is treated as an alarm state manager and the Latest Eventlog Payload will only contain the current state of this alarm.
When the Event Type is set to Alarm State Change Log (2), the Event is treated as an alarm that reports whenever the Alarm is either set or cleared. The Latest Eventlog Payload will contain all alarm transitions since the previous delivery in this mode.
When the Event Type is set to Event Log (3), this object instance is treated as a raw event log. It is used to manage and deliver events. The Latest Eventlog Payload will contain all events since the previous delivery in this mode.
See the Event Log Payload for examples of each of these modes.

<Description><![CDATA[The Latest Eventlog Payload resource is a read-only serialised Opaque (Binary) representation of all the Event Data between the Last Delivered Event Time and the Latest Recorded Event Time. When this payload is delivered to the LwM2M server, via either a read request or a confirmed observation on this Object, Object Instance or Resource, the Latest Delivered Interval should be updated. When no new data exists, an empty Opaque value should be provided.
The payload data can be provided in an implementation specific serialisation, but by default for fixed length values should use the OMA-LwM2M CBOR format encoded with one of these schemes:-
Event Type = Alarm Current State (1)
In this mode, only the current alarm state should be reported
1. 8-bit integer, value 2 representing OMA-LwM2M CBOR format.
2. Event Code [16-bit integer]
3. Event Type [8-bit Integer] - Alarm Current State (1)
4. Alarm Timestamp [32-bit unsigned integer] representing the number of seconds since Jan 1st, 1970 in the UTC time zone.
5. Alarm State [8-bit Integer]
