# StackInstanceResourceDriftsSummary
<a name="API_StackInstanceResourceDriftsSummary"></a>

The structure containing summary information about resource drifts for a stack instance.

## Contents
<a name="API_StackInstanceResourceDriftsSummary_Contents"></a>

 ** LogicalResourceId **   
The logical name of the resource specified in the template.  
Type: String  
Required: Yes

 ** ResourceType **   
Type of resource. For more information, see [AWS resource and property types reference](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-template-resource-type-ref.html) in the * AWS CloudFormation User Guide*.  
Type: String  
Length Constraints: Minimum length of 1. Maximum length of 256.  
Required: Yes

 ** StackId **   
The ID of the stack instance.  
Type: String  
Required: Yes

 ** StackResourceDriftStatus **   
The drift status of the resource in a stack instance.  
+  `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: String  
Valid Values: `IN_SYNC | MODIFIED | DELETED | NOT_CHECKED | UNKNOWN | UNSUPPORTED`   
Required: Yes

 ** Timestamp **   
Time at which the stack instance drift detection operation was initiated.  
Type: Timestamp  
Required: Yes

 ** PhysicalResourceId **   
The name or unique identifier that corresponds to a physical instance ID of a resource supported by CloudFormation.  
Type: String  
Required: No

 ** PhysicalResourceIdContext.member.N **   
Context information that enables CloudFormation to uniquely identify a resource. CloudFormation uses context key-value pairs in cases where a resource's logical and physical IDs aren't enough to uniquely identify that resource. Each context key-value pair specifies a unique resource that contains the targeted resource.  
Type: Array of [PhysicalResourceIdContextKeyValuePair](API_PhysicalResourceIdContextKeyValuePair.md) objects  
Array Members: Maximum number of 5 items.  
Required: No

 ** PropertyDifferences.member.N **   
Status of the actual configuration of the resource compared to its expected configuration. These will be present only for resources whose `StackInstanceResourceDriftStatus` is `MODIFIED`.   
Type: Array of [PropertyDifference](API_PropertyDifference.md) objects  
Required: No
