ScalingRules

• Implements: com.aliyun.ros.cdk.ess.datasource.IScalingRules

This class encapsulates and extends the ROS resource type DATASOURCE::ESS::ScalingRules, which are used to query the information about scaling rules.

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.

Methods

toString

public java.lang.String toString()

Returns a string representation of this construct.

synthesize

public void synthesize(ISynthesisSession session)

Allows this construct to emit artifacts into the cloud assembly during synthesis.

This method is usually implemented by framework-level constructs such as Stack and Asset as they participate in synthesizing the cloud assembly.

session^Required

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

The synthesis session.

addCondition

public void addCondition(RosCondition condition)

condition^Required

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

addCount

public void addCount(java.lang.Number OR IResolvable count)

count^Required

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

addDependency

public void addDependency(Resource resource)

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

fetchCondition

public RosCondition fetchCondition()

fetchDependency

public java.util.List<java.lang.String> fetchDependency()

fetchResourceDesc

public java.lang.String fetchResourceDesc()

getAtt

public IResolvable getAtt(java.lang.String name)

name^Required

• Type: java.lang.String

setMetadata

public void setMetadata(java.lang.String key, java.lang.Object value)

key^Required

• Type: java.lang.String

value^Required

• Type: java.lang.Object

Static Functions

isConstruct

import com.aliyun.ros.cdk.ess.datasource.ScalingRules;
ScalingRules.isConstruct(java.lang.Object x)

Return whether the given object is a Construct.

x^Required

• Type: java.lang.Object

Properties

node^Required

public ConstructNode getNode();

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

The construct tree node associated with this construct.

env^Required

public IResourceEnvironment getEnv();

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

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

ref^Required

public java.lang.String getRef();

stack^Required

public Stack getStack();

• Type: com.aliyun.ros.cdk.core.Stack

The stack in which this resource is defined.

attrScalingRuleIds^Required

public java.lang.Object getAttrScalingRuleIds();

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

attrScalingRules^Required

public java.lang.Object getAttrScalingRules();

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

Attribute ScalingRules: The list of scaling rules.

props^Required

public ScalingRulesProps getProps();
