In Cognite Data Fusion, the event resource type stores complex information that happens over a period. Events have a start time and an end time and can be related to multiple assets. For example, an event can describe two hours of maintenance on a water pump and associated pipes, or a future period when the pump is scheduled for inspection.


Time series is the resource type for storing a series of data points in time order, for example temperature measurements.

About events

The startTime and endTime for an event’s period are defined in milliseconds in Unix Epoch time. CDF doesn't support fractional milliseconds, and doesn't count leap seconds. You can specify start and end times in the future.

To describe and classify events, you can add arbitrary string values for description, metadata, type, and subtype.


See the events API documentation for more information about how to work with events.
