status |
String |
自动变配开关状态。 取值:
|
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。 |

Boolean |
自动回缩开关状态。 取值:
|
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 |
