scope^Required

• Type: com.aliyun.ros.cdk.core.Construct

---

id^Required

• Type: java.lang.String

---

enableResourcePropertyConstraint^Optional

• Type: java.lang.Boolean

---

refreshOptions^Optional

• Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property refreshOptions: The refresh strategy for the datasource resource when the stack is updated.

Valid values:

• Never: Never refresh the datasource resource when the stack is updated.
• Always: Always refresh the datasource resource when the stack is updated. Default is Never.

---

scalingGroupId^Optional

• Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property scalingGroupId: The ID of the scaling group.

---

scalingRuleAris^Optional

• Type: java.util.List OR com.aliyun.ros.cdk.core.IResolvable

Property scalingRuleAris: The unique identifiers of the scaling rules that you want to query.

---

scalingRuleIds^Optional

• Type: java.util.List OR com.aliyun.ros.cdk.core.IResolvable

Property scalingRuleIds: The IDs of the scaling rules that you want to query.

---

scalingRuleNames^Optional

• Type: java.util.List OR com.aliyun.ros.cdk.core.IResolvable

Property scalingRuleNames: The names of the scaling rules that you want to query.

---

scalingRuleType^Optional

• Type: java.lang.String OR com.aliyun.ros.cdk.core.IResolvable

Property scalingRuleType: The type of the scaling rule.

Valid values: SimpleScalingRule: adjusts the number of ECS instances based on the values of the AdjustmentType and AdjustmentValue parameters. TargetTrackingScalingRule: calculates the number of ECS instances that need to be scaled in a dynamic manner and maintains the value of a predefined metric close to the value of the TargetValue parameter. StepScalingRule: scales ECS instances in steps based on the specified thresholds and metric values. PredictiveScalingRule: uses machine learning to analyze historical monitoring data of the scaling group and predicts the future values of metrics. In addition, Auto Scaling automatically creates scheduled tasks to adjust the boundary values for the scaling group.

---

showAlarmRules^Optional

• Type: java.lang.Boolean OR com.aliyun.ros.cdk.core.IResolvable

Property showAlarmRules: Specifies whether to return the event-triggered tasks that are associated with the scaling rule.

Valid values: true false Default value: false.

resource^Required

• Type: com.aliyun.ros.cdk.core.Resource

---

addResourceDesc

public void addResourceDesc(java.lang.String desc)

desc^Required

• Type: java.lang.String

---

applyRemovalPolicy

public void applyRemovalPolicy(RemovalPolicy policy)

policy^Required

• Type: com.aliyun.ros.cdk.core.RemovalPolicy

---

getAtt

public IResolvable getAtt(java.lang.String name)

name^Required
