The unified alerting feature provided by Quota Center for quota items of Ecs Quotas by Instance Type can be used to improve the efficiency of alert configurations. After you configure a unified alert rule, Quota Center checks the available quotas of all the quota items of Ecs Quotas by Instance Type. You do not need to configure alerts for each quota item of Ecs Quotas by Instance Type.
Usage notes
The alert latency of a unified alert rule for quota items of Ecs Quotas by Instance Type is T+1. This indicates that a unified alert rule takes effect on the next day of the day you configure the rule. If you require a lower alert latency, we recommend that you configure alert rules for each quota item. The alert latency of such a rule is 15 minutes. For more information, see Create an alert rule for a quota item.
