get-asset-property-aggregates¶

Description¶

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 .

Synopsis¶

  get-asset-property-aggregates
[--asset-id <value>]
[--property-id <value>]
[--property-alias <value>]
--aggregate-types <value>
--resolution <value>
[--qualities <value>]
--start-date <value>
--end-date <value>
[--time-ordering <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <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 .

--aggregate-types (list)

The data aggregating function.

(string)

Syntax:

"string" "string" ...

Where valid values are:
  AVERAGE
  COUNT
  MAXIMUM
  MINIMUM
  SUM
  STANDARD_DEVIATION

--resolution (string)

The time interval over which to aggregate data.

--qualities (list)

The quality by which to filter asset data.

(string)

Syntax:

"string" "string" ...

Where valid values are:
  GOOD
  BAD
  UNCERTAIN

--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.

--time-ordering (string)

The chronological sorting order of the requested information.

Default: ASCENDING

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.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To retrieve an asset property’s aggregated average and count values

The following get-asset-property-aggregates example retrieves a wind turbine asset’s average total power and count of total power data points for a 1 hour period in time.

aws iotsitewise get-asset-property-aggregates \
    --asset-id a1b2c3d4-5678-90ab-cdef-33333EXAMPLE \
    --property-id a1b2c3d4-5678-90ab-cdef-66666EXAMPLE \
    --start-date 1580849400 \
    --end-date 1580853000 \
    --aggregate-types AVERAGE COUNT \
    --resolution 1h

Output:

{
    "aggregatedValues": [
        {
            "timestamp": 1580850000.0,
            "quality": "GOOD",
            "value": {
                "average": 8723.46538886233,
                "count": 12.0
            }
        }
    ]
}
