DescribeStackResourceDrifts

Returns drift information for the resources that have been checked for drift in the specified stack. This includes actual and expected configuration values for resources where CloudFormation detects configuration drift.

For a given stack, there will be one StackResourceDrift for each stack resource that has been checked for drift. Resources that haven't yet been checked for drift aren't included. Resources that don't currently support drift detection aren't checked, and so not included. For a list of resources that support drift detection, see Resource type support for imports and drift detection.

Use DetectStackResourceDrift to detect drift on individual resources, or DetectStackDrift to detect drift on all supported resources for a given stack.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

MaxResults

The maximum number of results to be returned with a single call. If the number of available results exceeds this maximum, the response includes a NextToken value that you can assign to the NextToken request parameter to get the next set of results.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 100.

Required: No

NextToken

A string that identifies the next page of stack resource drift results.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Required: No

StackName

The name of the stack for which you want drift information.

Type: String

Length Constraints: Minimum length of 1.

Pattern: ([a-zA-Z][-a-zA-Z0-9]*)|(arn:\b(aws|aws-us-gov|aws-cn)\b:[-a-zA-Z0-9:/._+]*)

Required: Yes

StackResourceDriftStatusFilters.member.N

The resource drift status values to use as filters for the resource drift results returned.

DELETED: The resource differs from its expected template configuration in that the resource has been deleted.
MODIFIED: One or more resource properties differ from their expected template values.
IN_SYNC: The resource's actual configuration matches its expected template configuration.
NOT_CHECKED: CloudFormation doesn't currently return this value.

Type: Array of strings

Array Members: Minimum number of 1 item. Maximum number of 4 items.

Valid Values: IN_SYNC | MODIFIED | DELETED | NOT_CHECKED

Required: No

Response Elements

The following elements are returned by the service.

NextToken

If the request doesn't return all the remaining results, NextToken is set to a token. To retrieve the next set of results, call DescribeStackResourceDrifts again and assign that token to the request object's NextToken parameter. If the request returns all results, NextToken is set to null.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

StackResourceDrifts.member.N

Drift information for the resources that have been checked for drift in the specified stack. This includes actual and expected configuration values for resources where CloudFormation detects drift.

For a given stack, there will be one StackResourceDrift for each stack resource that has been checked for drift. Resources that haven't yet been checked for drift aren't included. Resources that do not currently support drift detection aren't checked, and so not included. For a list of resources that support drift detection, see Resource type support for imports and drift detection.

Type: Array of StackResourceDrift objects
