Data Collection

List data collection item definitions

Retrieve the definitions (configuration) of all data collection items (DCIs) configured on the object. This returns the DCI configuration, not collected values - use the current-values and history endpoints for data. Enumerations such as origin, dataType, status and threshold function/condition are returned as symbolic names.

Requires OBJECT_ACCESS_READ and OBJECT_ACCESS_READ_DC_CONFIG on the object.
