See ‘aws help’ for descriptions of global parameters.

Synopsis

  describe-alarm-model
--alarm-model-name <value>
[--alarm-model-version <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--alarm-model-name (string)

The name of the alarm model.

--alarm-model-version (string)

The version of the alarm model.

--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.

--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.

You must use expressions for all parameters in DynamoDBv2Action . The expressions accept literals, operators, functions, references, and substitution templates.

Examples

• For literal values, the expressions must contain single quotes. For example, the value for the tableName parameter can be 'GreenhouseTemperatureTable' .
