AWS IoT SiteWise now provides the ability for customers to automatically compute aggregated asset property values every 15 minutes. Customers can now get aggregated values for asset properties, metrics and transforms (mathematical expressions that map asset properties' data points from one form to another) for every minute, 15-minute, hour, and day. AWS IoT SiteWise computes commonly used statistical aggregates such as average, count, maximum, minimum, standard deviation, and sum over multiple time intervals. Customers can map data streams and define static or computed equipment and process properties across all facilities so they're readily available for analysis. For non-numeric properties, such as Strings and Booleans, AWS IoT SiteWise computes only the count aggregate.

The ability to pre compute 15-minute aggregated asset property values has been a highly requested feature for customers who use AWS IoT SiteWise for energy and manufacturing industrial applications. Customers can automatically benefit from this feature by using the AWS IoT SiteWise GetAssetPropertyAggregates API. To use this API, customers will need to specify asset property identifiers, the time interval (1 minute, 15 minute, 1 hour, 1 day) and list of aggregates such as AVERAGE, COUNT, MAXIMUM, MINIMUM, STANDARD_DEVIATION, and SUM to retrieve aggregated values for an asset property. Customers can visualize 15 minutes auto-computed asset property aggregates using AWS SiteWise Monitor web applications, or retrieve them for feeding analytics applications.

This feature is available in all AWS regions where AWS IoT SiteWise is available. AWS IoT SiteWise is a managed service that enables customers to collect, store, organize and monitor data from industrial equipment at scale.
