list-datasets

Description

Retrieves information about datasets.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

list-datasets 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: datasetSummaries

Synopsis

  list-datasets
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To retrieve information about datasets

The following list-datasets example lists summary information about available datasets.

aws iotanalytics list-datasets

Output:

{
    "datasetSummaries": [
        {
            "status": "ACTIVE",
            "datasetName": "mydataset",
            "lastUpdateTime": 1557859240.658,
            "triggers": [],
            "creationTime": 1557859240.658,
            "actions": [
                {
                    "actionName": "query_32",
                    "actionType": "QUERY"
                }
            ]
        }
    ]
}

Output

datasetSummaries -> (list)

A list of DatasetSummary objects.

(structure)

A summary of information about a dataset.

datasetName -> (string)

The name of the dataset.

status -> (string)

The status of the dataset.

creationTime -> (timestamp)

The time the dataset was created.

lastUpdateTime -> (timestamp)

The last time the dataset was updated.

triggers -> (list)

A list of triggers. A trigger causes dataset content to be populated at a specified time interval or when another dataset is populated. The list of triggers can be empty or contain up to five DataSetTrigger objects

(structure)

The DatasetTrigger that specifies when the dataset is automatically updated.

schedule -> (structure)

The Schedule when the trigger is initiated.

expression -> (string)

The expression that defines when to trigger an update. For more information, see Schedule Expressions for Rules in the Amazon CloudWatch Events User Guide .

dataset -> (structure)

The dataset whose content creation triggers the creation of this dataset’s contents.

name -> (string)

The name of the dataset whose content generation triggers the new dataset content generation.

actions -> (list)

A list of DataActionSummary objects.

(structure)

Information about the action that automatically creates the dataset’s contents.

actionName -> (string)

The name of the action that automatically creates the dataset’s contents.

actionType -> (string)

The type of action by which the dataset’s contents are automatically created.

nextToken -> (string)

The token to retrieve the next set of results, or null if there are no more results.
