--detector-model-description (string)
A brief description of the detector model.
--key (string)
The input attribute key used to identify a device or system to create a detector (an instance of the detector model) and then to route each input received to the appropriate detector (instance). This parameter uses a JSON-path expression to specify the attribute-value pair in the message payload of each input that is used to identify the device associated with the input.
--role-arn (string)
The ARN of the role that grants permission to AWS IoT Events to perform its operations.
--tags (list)
Metadata that can be used to manage the detector model.
Shorthand Syntax:
key=string,value=string ...
JSON Syntax:
[
{
"key": "string",
"value": "string"
}
...
]
--evaluation-method (string)
When set to SERIAL , variables are updated and event conditions evaluated in the order that the events are defined. When set to BATCH , variables are updated and events performed only after all event conditions are evaluated.
Possible values:
- BATCH
- SERIAL
--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.
See 'aws help' for descriptions of global parameters.
Examples¶
To create a detector model
The following create-detector-model example creates a detector model with its configuration specified by a parameter file.
aws iotevents create-detector-model \
--cli-input-json file://motorDetectorModel.json
