intervalWindowInSeconds

The query interval for the window, in seconds. IoT SiteWise computes each interpolated value by using data points from the timestamp of each interval, minus the window to the timestamp of each interval plus the window. If not specified, the window ranges between the start time minus the interval and the end time plus the interval.

• If you specify a value for the intervalWindowInSeconds parameter, the value for the type parameter must be LINEAR_INTERPOLATION.

• If a data point isn't found during the specified query window, IoT SiteWise won't return an interpolated value for the interval. This indicates that there's a gap in the ingested data points. For example, you can get the interpolated temperature values for a wind turbine every 24 hours over a duration of 7 days. If the interpolation starts on July 1, 2021, at 9 AM with a window of 2 hours, IoT SiteWise uses the data points from 7 AM (9 AM minus 2 hours) to 11 AM (9 AM plus 2 hours) on July 2, 2021 to compute the first interpolated value. Next, IoT SiteWise uses the data points from 7 AM (9 AM minus 2 hours) to 11 AM (9 AM plus 2 hours) on July 3, 2021 to compute the second interpolated value, and so on.
