功能介绍

查询自动变配。

调用方法

请参见如何调用API

URI

GET /v3/{project_id}/instances/{instance_id}/auto-scaling/policy

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

租户在某一Region下的project ID。

获取方法请参见获取项目ID

instance_id

String

实例ID,严格匹配UUID规则。

请求参数

表2 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

String

用户Token。

通过调用IAM服务获取用户Token接口获取。

请求响应成功后在响应消息头中包含的“X-Subject-Token”的值即为Token值。

String

自动变配策略ID。

instance_id

String

实例ID。

instance_name

String

实例名称。

status

String

自动变配开关状态。

取值:

  • ON:已开启

  • OFF:已关闭

monitor_cycle

Integer

监测周期(单位:秒)。 在整个观测窗口期内,若CPU平均使用率大于等于设定值,则在观测窗口结束后,进行扩容。

silence_cycle

Integer

enlarge_threshold

Integer

扩容阈值(百分比数值),指CPU平均使用率。

max_flavor

String

扩容规格上限。

取值:

  • true:已开启

  • false:已关闭

min_flavor

String

缩容规格下限。

silence_start_at

String

静默期开始时间(上一次变更结束时间)。

格式为"yyyy-mm-ddThh:mm:ssZ"。 其中,T指某个时间的开始;Z指时区偏移量,例如北京时间偏移显示为+0800。

scaling_strategy

ScalingStrategyInfo object

自动变配策略。

max_read_only_count

Integer

只读节点数量上限。

min_read_only_count

Integer

只读节点数量下限。

read_only_weight

Integer

只读节点读写分离权重。

表4 ScalingStrategyInfo
