get_asset_property_value_history

get_asset_property_value_history(**kwargs)

Gets the history of an asset property's values. For more information, see Querying historical values in the 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

response = client.get_asset_property_value_history(
    assetId='string',
    propertyId='string',
    propertyAlias='string',
    startDate=datetime(2015, 1, 1),
    endDate=datetime(2015, 1, 1),
    qualities=[
        'GOOD'|'BAD'|'UNCERTAIN',
    ],
    timeOrdering='ASCENDING'|'DESCENDING',
    nextToken='string',
    maxResults=123
)

Parameters

• assetId (string) -- The ID of the asset.
• propertyId (string) -- The ID of the asset property.
• propertyAlias (string) -- 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 IoT SiteWise User Guide .
• startDate (datetime) -- The exclusive start of the range from which to query historical data, expressed in seconds in Unix epoch time.
• endDate (datetime) -- The inclusive end of the range from which to query historical data, expressed in seconds in Unix epoch time.
• qualities (list) --

  The quality by which to filter asset data.

  • (string) --
• timeOrdering (string) --

  The chronological sorting order of the requested information.

  Default: ASCENDING

• nextToken (string) -- The token to be used for the next set of paginated results.
• maxResults (integer) --

  The maximum number of results to return for each paginated request.

  Default: 100

    The asset property's value history.

    • (dict) --

      Contains asset property value information.

      • value (dict) --

        The value of the asset property (see Variant ).

        • stringValue (string) --

          Asset property data of type string (sequence of characters).

        • integerValue (integer) --

          Asset property data of type integer (whole number).
