Create a dimension that you can use to limit the scope of a metric used in a security profile for AWS IoT Device Defender. For example, using a TOPIC_FILTER
dimension, you can narrow down the scope of the metric only to MQTT topics whose name match the pattern specified in the dimension.

--name
(string)
A unique identifier for the dimension. Choose something that describes the type and value to make it easy to remember what it does.
--type
(string)
Specifies the type of dimension. Supported types:
TOPIC_FILTER.
Possible values:
TOPIC_FILTER
--string-values
(list)
Specifies the value or list of values for the dimension. For
TOPIC_FILTER
dimensions, this is a pattern used to match the MQTT topic (for example, “admin/#”).(string)
Syntax:
"string" "string" ...
--tags
(list)
Metadata that can be used to manage the dimension.
(structure)
A set of key/value pairs that are used to manage the resource.
Key -> (string)
The tag’s key.
Value -> (string)
The tag’s value.
Shorthand Syntax:
Key=string,Value=string ...
JSON Syntax:
[
{
"Key": "string",
"Value": "string"
}
...
]
--client-request-token
(string)
Each dimension must have a unique client request token. If you try to create a new dimension with the same token as a dimension that already exists, an exception occurs. If you omit this value, AWS SDKs will automatically generate a unique client request.
--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.
--cli-auto-prompt
(boolean)
Automatically prompt for CLI input parameters.
See ‘aws help’ for descriptions of global parameters.
To create a dimension
The following create-dimension
creates a dimension with a single topic filter called TopicFilterForAuthMessages
.
aws iot create-dimension \
--name TopicFilterForAuthMessages \
--type TOPIC_FILTER \
--string-values device/+/auth
Output:
{
"name": "TopicFilterForAuthMessages",
"arn": "arn:aws:iot:eu-west-2:123456789012:dimension/TopicFilterForAuthMessages"
}
For more information, see Detect Commands in the AWS IoT Developer Guide.
name -> (string)
A unique identifier for the dimension.
arn -> (string)
The ARN (Amazon resource name) of the created dimension.
