Description

Returns details about the reserved concurrency configuration for a function. To set a concurrency limit for a function, use PutFunctionConcurrency .

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  get-function-concurrency
--function-name <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options

--function-name (string)

The name of the Lambda function.

Name formats

• Function name - my-function .

• Function ARN - arn:aws:lambda:us-west-2:123456789012:function:my-function .

• Partial ARN - 123456789012:function:my-function .

The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

--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.

Examples

To view the reserved concurrency setting for a function

The following get-function-concurrency example retrieves the reserved concurrency setting for the specified function.

aws lambda get-function-concurrency \
    --function-name my-function

Output:

{
    "ReservedConcurrentExecutions": 250
}

Output

ReservedConcurrentExecutions -> (integer)

The number of simultaneous executions that are reserved for the function.
