get-asset-property-value-history

Description

Gets the history of an asset property’s values. For more information, see Querying Historical Property Values 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 .

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

get-asset-property-value-history is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: assetPropertyValueHistory

Synopsis

  get-asset-property-value-history
[--asset-id <value>]
[--property-id <value>]
[--property-alias <value>]
[--start-date <value>]
[--end-date <value>]
[--qualities <value>]
[--time-ordering <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options

--asset-id (string)

The ID of the asset.

--property-id (string)

The ID of the asset property.

--property-alias (string)

The property 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 .

--start-date (timestamp)

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

--end-date (timestamp)

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)

Syntax:

"string" "string" ...

Where valid values are:
  GOOD
  BAD
  UNCERTAIN

--time-ordering (string)

The chronological sorting order of the requested information.

Possible values:

  • ASCENDING

  • DESCENDING

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples

To retrieve an asset property’s historical values

The following get-asset-property-value-history example retrieves a wind turbine asset’s total power values for a 20 minute period in time.

aws iotsitewise get-asset-property-value-history \
    --asset-id a1b2c3d4-5678-90ab-cdef-33333EXAMPLE \
    --property-id a1b2c3d4-5678-90ab-cdef-66666EXAMPLE \
    --start-date 1580851800 \
    --end-date 1580853000

Output:
