Implements IConstruct, IDependable, IInspectable

The AWS::CE::AnomalySubscription resource (also referred to as an alert subscription) is a Cost Explorer resource type that sends notifications about specific anomalies that meet an alerting criteria defined by you.

You can specify the frequency of the alerts and the subscribers to notify.

Anomaly subscriptions can be associated with one or more AWS::CE::AnomalyMonitor resources, and they only send notifications about anomalies detected by those associated monitors. You can also configure a threshold to further control which anomalies are included in the notifications.

Anomalies that don’t exceed the chosen threshold and therefore don’t trigger notifications from an anomaly subscription will still be available on the console and from the GetAnomalies API.

addDeletionOverride(path)

public addDeletionOverride(path: string): void

Parameters

• path string — The path of the value to delete.

Syntactic sugar for addOverride(path, undefined).

---

addDependency(target)

public addDependency(target: CfnResource): void

Parameters

• target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

---

addDependsOn(target)⚠️

public addDependsOn(target: CfnResource): void

⚠️ Deprecated: use addDependency

Parameters

• target CfnResource

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

---

addMetadata(key, value)

public addMetadata(key: string, value: any): void

Parameters

• key string
• value any

Add a value to the CloudFormation Resource Metadata.

See also: [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)

---

addOverride(path, value)

public addOverride(path: string, value: any): void

Parameters

• path string — - The path of the property, you can use dot notation to override values in complex types.
• value any — - The value.

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with "Properties." (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example,

cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');

would add the overrides

"Properties": {
  "GlobalSecondaryIndexes": [
    {
      "Projection": {
        "NonKeyAttributes": [ "myattribute" ]
        ...
      }
      ...
    },
    {
      "ProjectionType": "INCLUDE"
      ...
    },
  ]
  ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

---

addPropertyDeletionOverride(propertyPath)

public addPropertyDeletionOverride(propertyPath: string): void

Parameters

• propertyPath string — The path to the property.

Adds an override that deletes the value of a property from the resource definition.

---

addPropertyOverride(propertyPath, value)

public addPropertyOverride(propertyPath: string, value: any): void

Parameters

• propertyPath string — The path of the property.
• value any — The value.

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

---

applyRemovalPolicy(policy?, options?)

public applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): void

Parameters

• policy RemovalPolicy
• options RemovalPolicyOptions

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you've removed it from the CDK application or because you've made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

---

getAtt(attributeName, typeHint?)

public getAtt(attributeName: string, typeHint?: ResolutionTypeHint): Reference

Parameters

• attributeName string — The name of the attribute.
• typeHint ResolutionTypeHint

Returns

• Reference

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

---

getMetadata(key)

public getMetadata(key: string): any

Parameters

• key string

Returns

• any

Retrieve a value value from the CloudFormation Resource Metadata.

See also: [https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.)
