     Table 2 Alarm parameters

     Parameter	Description
     Method	You are advised to select Use existing template. The existing templates already contain three common alarm metrics: CPU usage, memory usage, and storage space usage. NOTE: If you select Associate template, after the associated template is modified, the policies contained in this alarm rule to be created will be modified accordingly.
     Template	Select the template to be used. You can select a default alarm template or create a custom template.
     Alarm Policy	If you select Configure manually for Method, you need to configure alarm policies. An alarm is triggered when the metric configured for this alarm reaches the preset threshold in consecutive periods. For example, Cloud Eye triggers an alarm if the average CPU usage of the monitored object is 80% or more for three consecutive 5-minute periods. NOTE: A maximum of 50 alarm policies can be added to an alarm rule. If any one of these alarm policies is met, an alarm is triggered.
     Alarm Severity	If you select Configure manually for Method, you need to configure alarm severity. The alarm severity can be Critical, Major, Minor, or Informational.

     Notification Group	Notification group the alarm notification is to be sent to.
     Notification Object	Object the alarm notification is to be sent to. You can select the account contact or a topic.
