If you select Specific dimension, only metrics of the specified dimension can be configured for the same alarm rule.	KMS key
   Monitoring Scope	Monitoring scope the alarm rule applies to. All resources: An alarm will be triggered if any resource of the current cloud product meets the alarm policy.

When you set Alarm Type to Metric, whether to trigger an alarm depends on whether the data in consecutive periods reaches the threshold. For example, an alarm is triggered if the average CPU usage is 80% or higher for three consecutive 5-minute periods. When you set Alarm Type is to Event and a specific event occurs, an alarm is triggered. For example, an alarm is triggered if a VM is restarted.	-
