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.
