Lambda.Client.list_provisioned_concurrency_configs(**kwargs)

Retrieves a list of provisioned concurrency configurations for a function.

Request Syntax

response = client.list_provisioned_concurrency_configs(
    FunctionName='string',
    Marker='string',
    MaxItems=123
)

Parameters:

• FunctionName (string) –

  [REQUIRED]

  The name or ARN 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.

• Marker (string) – Specify the pagination token that’s returned by a previous request to retrieve the next page of results.

• MaxItems (integer) – Specify a number to limit the number of configurations returned.

Return type:

dict

Response Structure

• (dict) –

  • ProvisionedConcurrencyConfigs (list) –

    A list of provisioned concurrency configurations.

    • (dict) –

      Details about the provisioned concurrency configuration for a function alias or version.

      • FunctionArn (string) –

        The Amazon Resource Name (ARN) of the alias or version.

      • RequestedProvisionedConcurrentExecutions (integer) –

        The amount of provisioned concurrency requested.

      • AvailableProvisionedConcurrentExecutions (integer) –

        The amount of provisioned concurrency available.

      • AllocatedProvisionedConcurrentExecutions (integer) –

        The amount of provisioned concurrency allocated. When a weighted alias is used during linear and canary deployments, this value fluctuates depending on the amount of concurrency that is provisioned for the function versions.

      • Status (string) –

        The status of the allocation process.

      • StatusReason (string) –

        For failed allocations, the reason that provisioned concurrency could not be allocated.

      • LastModified (string) –

        The date and time that a user last updated the configuration, in ISO 8601 format.

  • NextMarker (string) –

    The pagination token that’s included if more results are available.

Exceptions

• Lambda.Client.exceptions.InvalidParameterValueException

• Lambda.Client.exceptions.ResourceNotFoundException

• Lambda.Client.exceptions.TooManyRequestsException

• Lambda.Client.exceptions.ServiceException

Examples

The following example returns a list of provisioned concurrency configurations for a function named my-function.

response = client.list_provisioned_concurrency_configs(
    FunctionName='my-function',
)

print(response)
