GetAssetPropertyAggregates - AWS IoT SiteWise

GetAssetPropertyAggregates

Gets aggregated values for an asset property. For more information, see Querying aggregates in the AWS IoT SiteWise User Guide.

To identify an asset property, you must specify one of the following:

  • The assetId and propertyId of an asset property.

  • A propertyAlias, which is a data stream alias (for example, /company/windfarm/3/turbine/7/temperature). To define an asset property's alias, see UpdateAssetProperty.

Request Syntax

GET /properties/aggregates?aggregateTypes=aggregateTypes&assetId=assetId&endDate=endDate&maxResults=maxResults&nextToken=nextToken&propertyAlias=propertyAlias&propertyId=propertyId&qualities=qualities&resolution=resolution&startDate=startDate&timeOrdering=timeOrdering HTTP/1.1

URI Request Parameters

The request uses the following URI parameters.

aggregateTypes

The data aggregating function.

Array Members: Minimum number of 1 item.

Valid Values: AVERAGE | COUNT | MAXIMUM | MINIMUM | SUM | STANDARD_DEVIATION

Required: Yes

assetId

The ID of the asset, in UUID format.

Length Constraints: Fixed length of 36.

Length Constraints: Minimum length of 1. Maximum length of 4096.

Pattern: [A-Za-z0-9+/=]+

propertyAlias

The alias that identifies the property, such as an OPC-UA server data stream path (for example, /company/windfarm/3/turbine/7/temperature). For more information, see Mapping industrial data streams to asset properties in the AWS IoT SiteWise User Guide.

Length Constraints: Minimum length of 1. Maximum length of 1000.

Pattern: [^\u0000-\u001F\u007F]+

propertyId

The ID of the asset property, in UUID format.

Length Constraints: Fixed length of 36.

Pattern: ^[0-9a-f]{8}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{4}-[0-9a-f]{12}$

qualities

The quality by which to filter asset data.

Array Members: Fixed number of 1 item.

Valid Values: GOOD | BAD | UNCERTAIN

resolution

The time interval over which to aggregate data.

Length Constraints: Minimum length of 2. Maximum length of 3.

Pattern: 1m|15m|1h|1d

Required: Yes

startDate

The exclusive start of the range from which to query historical data, expressed in seconds in Unix epoch time.

Required: Yes

timeOrdering

The chronological sorting order of the requested information.

Default: ASCENDING

Valid Values: ASCENDING | DESCENDING
