[ aws . iotsitewise ]
Gets an asset property's current value. For more information, see Querying current values in the IoT SiteWise User Guide .
To identify an asset property, you must specify one of the following:
assetId
and propertyId
of an asset property.propertyAlias
, which is a data stream alias (for example, /company/windfarm/3/turbine/7/temperature
). To define an asset property's alias, see UpdateAssetProperty .See also: AWS API Documentation
See 'aws help' for descriptions of global parameters.
get-asset-property-value
[--asset-id <value>]
[--property-id <value>]
[--property-alias <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]
--asset-id
(string)
The ID of the asset.
--property-id
(string)
The ID of the asset property.
--property-alias
(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 .
--cli-input-json
(string)
Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command.
See 'aws help' for descriptions of global parameters.
To retrieve an asset property's current value
The following get-asset-property-value
example retrieves a wind turbine asset's current total power.
aws iotsitewise get-asset-property-value \
--asset-id a1b2c3d4-5678-90ab-cdef-33333EXAMPLE \
--property-id a1b2c3d4-5678-90ab-cdef-66666EXAMPLE
Output:
