AWS CLI Command Reference

[ aws . iotevents ]

describe-detector-model

Description

Describes a detector model. If the version parameter is not specified, information about the latest version is returned.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

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

Options

--detector-model-name (string)

The name of the detector model.

--detector-model-version (string)

The version of the detector 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.

See ‘aws help’ for descriptions of global parameters.

Examples

To get information about a detector model

The following describe-detector-model example displays details for the specified detector model. Because the version parameter is not specified, information about the latest version is returned.

aws iotevents describe-detector-model \
    --detector-model-name motorDetectorModel

  • 'UPDATE' - Update an existing item of the DynamoDB table with new data. This item’s partition key must match the specified hash key. If you specified a range key, the range key must match the item’s sort key.

  • 'DELETE' - Delete an existing item of the DynamoDB table. This item’s partition key must match the specified hash key. If you specified a range key, the range key must match the item’s sort key.

If you don’t specify this parameter, AWS IoT Events triggers the 'INSERT' operation.

The name of the DynamoDB column that receives the action payload.

If you don’t specify this parameter, the name of the DynamoDB column is payload .

tableName -> (string)

The name of the DynamoDB table. The tableName value must match the table name of the target DynamoDB table.

payload -> (structure)

Information needed to configure the payload.

By default, AWS IoT Events generates a standard payload in JSON for any action. This action payload contains all attribute-value pairs that have the information about the detector model instance and the event triggered the action. To configure the action payload, you can use contentExpression .

contentExpression -> (string)

The content of the payload. You can use a string expression that includes quoted strings ('<string>' ), variables ($variable.<variable-name> ), input values ($input.<input-name>.<path-to-datum> ), string concatenations, and quoted strings that contain ${} as the content. The recommended maximum size of a content expression is 1 KB.

type -> (string)

The value of the payload type can be either STRING or JSON .

dynamoDBv2 -> (structure)

Writes to the DynamoDB table that you created. The default action payload contains all attribute-value pairs that have the information about the detector model instance and the event that triggered the action. You can customize the payload . A separate column of the DynamoDB table receives one attribute-value pair in the payload that you specify. For more information, see Actions in AWS IoT Events Developer Guide .

key -> (string)

The value used to identify a detector instance. When a device or system sends input, a new detector instance with a unique key value is created. AWS IoT Events can continue to route input to its corresponding detector instance based on this identifying information.

This parameter uses a JSON-path expression to select the attribute-value pair in the message payload that is used for identification. To route the message to the correct detector instance, the device must send a message payload that contains the same attribute-value.
