}URI Request Parameters
The request does not use any URI parameters.
Request Body
The request accepts the following data in JSON format.
- detectorModelDefinition
-
Information that defines how the detectors operate.
Type: DetectorModelDefinition object
Required: Yes
- detectorModelDescription
-
A brief description of the detector model.
Type: String
Length Constraints: Maximum length of 1024.
Required: No
- detectorModelName
-
The name of the detector model.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 128.
Pattern:
^[a-zA-Z0-9_-]+$Required: Yes
- evaluationMethod
-
Information about the order in which events are evaluated and how actions are executed.
Default:
BATCHType: String
Valid Values:
BATCH | SERIALRequired: No
- key
-
The input attribute key used to identify a device or system to create a detector (an instance of the detector model) and then to route each input received to the appropriate detector (instance). This parameter uses a JSON-path expression in the message payload of each input to specify the attribute-value pair that is used to identify the device associated with the input.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 128.
Pattern:
^((`[\w\- ]+`)|([\w\-]+))(\.((`[\w- ]+`)|([\w\-]+)))*$Required: No
- roleArn
-
The ARN of the role that grants permission to Amazon IoT Events to perform its operations.
Type: String
Length Constraints: Minimum length of 1. Maximum length of 2048.
Required: Yes
-
Metadata that can be used to manage the detector model.
Type: Array of Tag objects
Required: No
