[ aws . events ]



Lists the targets assigned to the specified rule.

See also: AWS API Documentation

See 'aws help' for descriptions of global parameters.


--rule <value>
[--next-token <value>]
[--limit <value>]
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]


--rule (string)

The name of the rule.

--next-token (string)

The token returned by a previous call to retrieve the next set of results.

--limit (integer)

The maximum number of results to return.

--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.

--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.


To display all the targets for a CloudWatch Events rule

This example displays all the targets of the rule named DailyLambdaFunction:

aws events list-targets-by-rule --rule  "DailyLambdaFunction"


Targets -> (list)

The targets assigned to the rule.


Targets are the resources to be invoked when a rule is triggered. Target types include EC2 instances, AWS Lambda functions, Amazon Kinesis streams, Amazon ECS tasks, AWS Step Functions state machines, Run Command, and built-in targets.

Id -> (string)

The ID of the target.

Arn -> (string)

The Amazon Resource Name (ARN) of the target.

RoleArn -> (string)

The Amazon Resource Name (ARN) of the IAM role to be used for this target when the rule is triggered. If one rule triggers multiple targets, you can use a different IAM role for each target.

Input -> (string)

Valid JSON text passed to the target. In this case, nothing from the event itself is passed to the target. For more information, see The JavaScript Object Notation (JSON) Data Interchange Format .

InputPath -> (string)

The value of the JSONPath that is used for extracting part of the matched event when passing it to the target. You must use JSON dot notation, not bracket notation. For more information about JSON paths, see JSONPath .

InputTransformer -> (structure)

Settings to enable you to provide custom input to a target based on certain event data. You can extract one or more key-value pairs from the event and then use that data to send customized input to the target.

InputPathsMap -> (map)

Map of JSON paths to be extracted from the event. These are key-value pairs, where each value is a JSON path. You must use JSON dot notation, not bracket notation.

key -> (string)

value -> (string)

InputTemplate -> (string)

Input template where you can use the values of the keys from InputPathsMap to customize the data sent to the target.

KinesisParameters -> (structure)

The custom parameter you can use to control shard assignment, when the target is an Amazon Kinesis stream. If you do not include this parameter, the default is to use the eventId as the partition key.

PartitionKeyPath -> (string)

The JSON path to be extracted from the event and used as the partition key. For more information, see Amazon Kinesis Streams Key Concepts in the Amazon Kinesis Streams Developer Guide .

RunCommandParameters -> (structure)

Parameters used when you are using the rule to invoke Amazon EC2 Run Command.

RunCommandTargets -> (list)

Currently, we support including only one RunCommandTarget block, which specifies either an array of InstanceIds or a tag.


Information about the EC2 instances that are to be sent the command, specified as key-value pairs. Each RunCommandTarget block can include only one key, but this key may specify multiple values.

Key -> (string)

Can be either tag: tag-key or InstanceIds .

Values -> (list)

If Key is tag: tag-key , Values is a list of tag values. If Key is InstanceIds , Values is a list of Amazon EC2 instance IDs.


EcsParameters -> (structure)

Contains the Amazon ECS task definition and task count to be used, if the event target is an Amazon ECS task. For more information about Amazon ECS tasks, see Task Definitions in the Amazon EC2 Container Service Developer Guide .

TaskDefinitionArn -> (string)

The ARN of the task definition to use if the event target is an Amazon ECS cluster.

TaskCount -> (integer)

The number of tasks to create based on the TaskDefinition . The default is one.

BatchParameters -> (structure)

Contains the job definition, job name, and other parameters if the event target is an AWS Batch job. For more information about AWS Batch, see Jobs in the AWS Batch User Guide .

JobDefinition -> (string)

The ARN or name of the job definition to use if the event target is an AWS Batch job. This job definition must already exist.

JobName -> (string)

The name to use for this execution of the job, if the target is an AWS Batch job.

ArrayProperties -> (structure)

The array properties for the submitted job, such as the size of the array. The array size can be between 2 and 10,000. If you specify array properties for a job, it becomes an array job. This parameter is used only if the target is an AWS Batch job.

Size -> (integer)

The size of the array, if this is an array batch job. Valid values are integers between 2 and 10,000.

RetryStrategy -> (structure)

The retry strategy to use for failed jobs, if the target is an AWS Batch job. The retry strategy is the number of times to retry the failed job execution. Valid values are 1 to 10. When you specify a retry strategy here, it overrides the retry strategy defined in the job definition.

Attempts -> (integer)

The number of times to attempt to retry, if the job fails. Valid values are 1 to 10.

SqsParameters -> (structure)

Contains the message group ID to use when the target is a FIFO queue.

MessageGroupId -> (string)

The FIFO message group ID to use as the target.

NextToken -> (string)

Indicates whether there are additional results to retrieve. If there are no more results, the value is null.
