--domain-name (string)

The domain name for which you want Auto-Tune action details.

--max-results (integer)

Set this value to limit the number of results returned. If not specified, defaults to 100.

--next-token (string)

NextToken is sent in case the earlier API call results contain the NextToken. Used for pagination.

--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.
