Metric
import type { Metric } from "https://aws-api.deno.dev/v0.3/services/iotsitewise.ts?docs=full";
Contains an asset metric property. With metrics, you can calculate aggregate functions, such as an average, maximum, or minimum, as specified through an expression. A metric maps several values to a single value (such as a sum).
The maximum number of dependent/cascading variables used in any one metric calculation is 10.
Therefore, a root metric can have up to 10 cascading metrics in its computational dependency tree.
Additionally, a metric can only have a data type of DOUBLE
and consume properties with data types of INTEGER
or DOUBLE
.
For more information, see Metrics in the IoT SiteWise User Guide.
§Properties
The processing configuration for the given metric property. You can configure metrics to be computed at the edge or in the Amazon Web Services Cloud. By default, metrics are forwarded to the cloud.
The list of variables used in the expression.
The window (time interval) over which IoT SiteWise computes the metric's aggregation expression.
IoT SiteWise computes one data point per window
