Auto Scaling:DescribeScalingGroupDetail

The virtual private cloud (VPC) ID of the scaling group.

The time when the scaling group was created.

The total number of Elastic Compute Service (ECS) instances in the scaling group.

The name of the scaling group. The name of each scaling group must be unique in a region.

The name must be 2 to 64 characters in length, and can contain letters, digits, underscores (_), hyphens (-), and periods (.). It must start with a letter or digit.

The number of instance types that are specified. Preemptible instances of multiple lowest-priced instance types are evenly distributed across the zones of the scaling group. Valid values: 0 to 10.

The number of instances that are stopped in Economical Mode in the scaling group.

The percentage of pay-as-you-go instances among the excess instances when the minimum number of pay-as-you-go instances reaches the requirement. Valid values: 0 to 100.

The time when the scaling group was modified.

The minimum number of ECS instances that must be contained in the scaling group.

The ID of the scaling group.

Indicates whether pay-as-you-go ECS instances can be automatically created to reach the required number of ECS instances when preemptible ECS instances cannot be created due to high prices or insufficient inventory of resources. This parameter takes effect when you set MultiAZPolicy to COST_OPTIMIZED. Valid values:

• true
• false

The reclaim mode of the scaling group. Valid values:

• recycle: economical mode
• release: release mode
• forcerelease: forced release mode
• forcerecycle: forced recycle mode

For more information, see RemoveInstances .

The number of ECS instances that are in the Pending Remove state in the scaling group.

The number of ECS instances that are in the In Service state in the scaling group.

The minimum number of pay-as-you-go instances that must be contained in the scaling group. Valid values: 0 to 1000. If the number of pay-as-you-go instances in the scaling group is less than the value of this parameter, Auto Scaling preferentially creates pay-as-you-go instances.

The number of ECS instances that are in the Protected state in the scaling group.

The health check mode of the scaling group. Valid values:

• NONE: Auto Scaling does not perform health checks.
• ECS: Auto Scaling checks the health status of instances in the scaling group. If you want to enable instance health check, you can set the value to ECS, regardless of whether the scaling group is of ECS type or Elastic Container Instance type.
• LOAD_BALANCER: Auto Scaling checks the health status of instances in the scaling group based on the health check results of load balancers. The health check results of Classic Load Balancer (CLB) instances are not supported as the health check basis for instances in the scaling group.

The status of the scaling group. Valid values:

• Active: The scaling group is in the Enabled state. Enabled scaling groups can receive requests to execute scaling rules and trigger scaling activities.
• Inactive: The scaling group is in the Disabled state. Disabled scaling groups cannot receive requests to execute scaling rules.
• Deleting: The scaling group is being deleted. Scaling groups that are being deleted cannot receive requests to execute scaling rules, and the parameter settings of the scaling groups cannot be modified.

Indicates whether Deletion Protection is enabled for the scaling group. Valid values:

• true: Deletion Protection is enabled for the scaling group. This way, the scaling group cannot be deleted.
• false: Deletion Protection is disabled for the scaling group.

The ID of the active scaling configuration in the scaling group.

The type of the instances that are managed by the scaling group. Valid values:

• ECS: ECS instances
• ECI: elastic container instances

The scaling policy of the ECS instances in the multi-zone scaling group. Valid values:

• PRIORITY: ECS instances are created based on the value of VSwitchIds. If Auto Scaling cannot create ECS instances in the zone where the vSwitch of the highest priority resides, Auto Scaling creates ECS instances in the zone where the vSwitch of the next highest priority resides.

• COST_OPTIMIZED: ECS instances are created based on the unit prices of their vCPUs. Auto Scaling preferentially creates ECS instances that use the lowest-priced vCPUs. If preemptible instance types are specified in the scaling configuration, Auto Scaling preferentially creates preemptible instances. You can also specify CompensateWithOnDemand to allow Auto Scaling to create pay-as-you-go instances in the case that preemptible instances cannot be created due to insufficient inventory of preemptible instance types.

  **

  Note The COST_OPTIMIZED setting takes effect only if you specified multiple instance types or preemptible instance types in your scaling configuration.

• BALANCE: ECS instances are evenly distributed across the zones of the scaling group. If ECS instance are unevenly distributed across the specified zones due to insufficient inventory of instance types, you can call the RebalanceInstance operation to rebalance the distribution of the ECS instances.

The number of ECS instances that are being removed from the scaling group.

The number of ECS instances that are in the Pending Add state in the scaling group.

The number of ECS instances that are in the Standby state in the scaling group.

The number of ECS instances that are being added to the scaling group and configured.

The ID of the launch template that is used by the scaling group.

The total weighted capacity of all ECS instances in the scaling group if Weighted is specified. In other cases, the value of this parameter indicates the total number of ECS instances in the scaling group.

The expected number of ECS instances in the scaling group. Auto Scaling automatically maintains the expected number of ECS instances.

Indicates whether preemptible instances can be supplemented. If this parameter is set to true, Auto Scaling creates an instance to replace a preemptible instance when Auto Scaling receives the system message which indicates that the preemptible instance is to be reclaimed.

The version number of the launch template.

The region ID of the scaling group.

The vSwitch ID of the scaling group.

The maximum number of ECS instances that can be contained in the scaling group.

The cooldown period of the scaling group. Unit: seconds.

The backend vServer groups.

The information about the instance types that are extended in the launch template.

The information about the Application Load Balancer (ALB) server groups.

The information about the server groups.

The instance removal policies.

The IDs of the ApsaraDB RDS instances that are associated with the scaling group.

The IDs of the SLB instances that are associated with the scaling group.

The IDs of the vSwitches that are associated with the scaling group. If you specify VSwitchIds, VSwitchId is ignored.

The processes that are suspended. If no process is suspended, null is returned. Valid values:

• ScaleIn: scale-in
• ScaleOut: scale-out
• HealthCheck: health check
• AlarmNotification: event-triggered task
• ScheduledAction: scheduled task

Indicates whether Auto Scaling stops executing scaling activities in the scaling group. Valid values:

• true: Auto Scaling stops executing scaling activities in the scaling group if the scaling activities failed for more than seven consecutive days in the scaling group. You must modify the scaling group or scaling configuration to resume the execution of the scaling activities.
• false: Auto Scaling does not stop executing scaling activities in the scaling group.

The ID of the CloudMonitor application group that is associated with the scaling group.

Indicates whether instances in the scaling group are evenly distributed across zones. This parameter takes effect only if you set MultiAZPolicy to COMPOSABLE. Valid values:

• true
• false

The allocation policy of instances. Auto Scaling selects instance types based on the allocation policy to create the required number of instances. You can apply the policy to pay-as-you-go instances and preemptible instances. This parameter takes effect only if you set MultiAZPolicy to COMPOSABLE. Valid values:

• priority: Auto Scaling selects instance types based on the specified order to create the required number of instances.
• lowestPrice: Auto Scaling selects instance types that have the lowest unit price of vCPUs to create the required number of instances.

The allocation policy of preemptible instances. Auto Scaling selects instance types based on the allocation policy to create the required number of preemptible instances. You can apply the policy to pay-as-you-go instances and preemptible instances. This parameter takes effect only if you set MultiAZPolicy to COMPOSABLE. Valid values:

• priority: Auto Scaling selects instance types based on the specified order to create the required number of preemptible instances.
• lowestPrice: Auto Scaling selects instance types that have the lowest unit price of vCPUs to create the required number of preemptible instances.

The maximum life span of an instance in the scaling group. Unit: seconds.

Valid values: 0 or from 86400 to Integer.maxValue. A value of 0 for MaxInstanceLifetime indicates that any previously set limit has been removed, which effectively disables the maximum instance lifetime constraint.

Default value: null.

The Alibaba Cloud Resource Name (ARN) of the function that is specified in the custom scale-in policy. This parameter takes effect only if you set the first value of RemovalPolicies to CustomPolicy.

The number of instances that are in the Initialized state and not added to the scaling group.

The ID of the resource group to which the scaling group belongs.

The CLB configurations.

Indicates whether the Expected Number of Instances feature is enabled. Valid values:

• true
• false

The tags of the scaling group.

The health check mode of the scaling group. Valid values:

• NONE: Auto Scaling does not perform health checks.
• ECS: Auto Scaling checks the health status of instances in the scaling group. If you want to enable instance health check, you can set the value to ECS, regardless of whether the scaling group is of ECS type or Elastic Container Instance type.
• LOAD_BALANCER: Auto Scaling checks the health status of instances in the scaling group based on the health check results of load balancers. The health check results of CLB instances are not supported as the health check basis for instances in the scaling group.
