list-assets

Description

Retrieves a paginated list of asset summaries.

You can use this operation to do the following:

  • List assets based on a specific asset model.

  • List top-level assets.

You can’t use this operation to list all assets. To retrieve summaries for all of your assets, use ListAssetModels to get all of your asset model IDs. Then, use ListAssets to get all assets for each asset model.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

list-assets 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: assetSummaries

Synopsis

  list-assets
[--asset-model-id <value>]
[--filter <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-model-id (string)

The ID of the asset model by which to filter the list of assets. This parameter is required if you choose ALL for filter .

--filter (string)

The filter for the requested list of assets. Choose one of the following options. Defaults to ALL .

  • ALL – The list includes all assets for a given asset model ID. The assetModelId parameter is required if you filter by ALL .

  • TOP_LEVEL – The list includes only top-level assets in the asset hierarchy tree.

Possible values:

  • ALL

  • TOP_LEVEL

--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

Example 1: To list all top-level assets

The following list-assets example lists all assets that are top-level in the asset hierarchy tree and defined in your AWS account in the current Region.

aws iotsitewise list-assets \
    --filter TOP_LEVEL

Output:

{
    "assetSummaries": [
        {
            "id": "a1b2c3d4-5678-90ab-cdef-44444EXAMPLE",
            "arn": "arn:aws:iotsitewise:us-west-2:123456789012:asset/a1b2c3d4-5678-90ab-cdef-44444EXAMPLE",
            "name": "Wind Farm 1",
            "assetModelId": "a1b2c3d4-5678-90ab-cdef-22222EXAMPLE",
            "creationDate": 1575672453.0,
            "lastUpdateDate": 1575672453.0,
            "status": {
                "state": "ACTIVE"
            },
            "hierarchies": [
                {
                    "id": "a1b2c3d4-5678-90ab-cdef-77777EXAMPLE",
                    "name": "Wind Turbines"
                }
            ]
        }
    ]
}

Example 2: To list all assets based on an asset model

The following list-assets example lists all assets based on an asset model and defined in your AWS account in the current Region.

aws iotsitewise list-assets \
    --asset-model-id a1b2c3d4-5678-90ab-cdef-11111EXAMPLE

Output:

{
    "assetSummaries": [
        {
            "id": "a1b2c3d4-5678-90ab-cdef-33333EXAMPLE",
            "arn": "arn:aws:iotsitewise:us-west-2:123456789012:asset/a1b2c3d4-5678-90ab-cdef-33333EXAMPLE",
            "name": "Wind Turbine 1",
            "assetModelId": "a1b2c3d4-5678-90ab-cdef-11111EXAMPLE",
            "creationDate": 1575671550.0,
            "lastUpdateDate": 1575686308.0,
            "status": {
                "state": "ACTIVE"
            },
            "hierarchies": []
        }
    ]
}
