list_provisioned_concurrency_configs#

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.

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)
