Discriminator for the measurement type, always "measurement".
OptionaldestinationFor messages sent by data preparation, this is "cumulocity" by default, but can be set to other options for other destinations. For messages received by data preparation this is not set.
Since we usually don't know the C8Y ID to put in the payload, the data preparation rule can specify a single external ID to lookup (and automatically create if it does not exist). it is mandatory to include one item when sending this (unless the internal C8Y "id" is known and passed in the payload, or it's an operation where there's a dedicated field). When a Cumulocity message (e.g. operation) is received, this will contain a list of ALL external ids for this Cumulocity device.
The measurement data, including type, time, and custom fragments.
Creates a Cumulocity Measurement. Extends the base CumulocityObject.
Remarks
This interface models a measurement as received or sent to the Cumulocity platform. The
payloadcontains the measurement details, including its type, timestamp, and any number of custom fragments representing measurement series or additional data.
