      Table 2 Alarm rule parameters

      Parameter	Description	Example Value
      Alarm Type	Specifies the alarm type to which the alarm rule applies. The type can be Metric or Event.	Metric
      Cloud Product	This parameter is only available if Metric is selected for Alarm Type. Select a cloud product from the drop-down list. For details about supported cloud products and their metrics, see Services Monitored by Cloud Eye.	Elastic Cloud Server - ECSs
      Resource Level	This parameter is only available if Metric is selected for Alarm Type. Two options are available: Cloud product (recommended) and Specific dimension. Take ECS as an example. ECSs is the cloud product. Specific dimensions are disks, mount points, processes, and more.	Cloud product
      Monitoring Scope	This parameter is only available if Metric is selected for Alarm Type. Three options are available: All resources, Resource groups, or Specified resources. NOTE: All resources: An alarm will be triggered if any resource of the current cloud product meets the alarm policy. To exclude resources that do not require monitoring, click Select Resources to Exclude. Resource groups: An alarm will be triggered if any resource in the to-be-selected resource group meets the alarm policy. Specified resources: Click Select Specific Resources to select resources.	All resources
      Group	This parameter is available only if Metric is selected for Alarm Type and Resource groups for Monitoring Scope.	N/A
      Instance	This parameter is available only if Metric is selected for Alarm Type and Specific resources for Monitoring Scope.	N/A
      Threshold Type	For ECSs, you can select Static or Dynamic. The feature is available only in the CN South-Guangzhou region. Static: Indicates the fixed value set in an alarm rule. If the fixed value is reached, an alarm will be triggered. Dynamic: Indicates the predicative value range calculated based on historical data. If the current metric data deviates from the predicted value range, an alarm will be triggered.	Static
      Event Type	This parameter is only available if Event is selected for Alarm Type. You can select either System event or Custom event.	System event
      Event Source	This parameter is only available if Event is selected for Alarm Type. If System event is selected for Event Type, select the cloud service from which the event comes. Example value: Elastic Cloud Server If Custom event is selected for Event Type, the event source must be the same as that of the reported fields and written in the service.item format.	N/A
      Method	Configure manually: If Event is selected for Alarm Type and Custom Event for Event Type, Method is set to Configure manually by default. Associate template: After an associated template is modified, the policies contained in this alarm rule to be created will be modified accordingly.	Configure manually
      Template	You need to select a default template in either of the following conditions: Metric is selected for Alarm Type and Associate template is selected for Method. Event is selected for Alarm Type, System event is selected for Event Type, and Associate template is selected for Method. You can also customize an alarm template.	N/A
      Alarm Policy	If Event is selected for Alarm Type and Custom event is selected for Event Type, you need to set Alarm Policy. If Custom event is selected for Event Type, as long as an event occurs, an alarm will be triggered. If there is an event, such as improper ECS running, Cloud Eye triggers an alarm. For details, see Alarm Policies. 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 will be triggered.	N/A
      Alarm Severity	Specifies the alarm severity, which can be Critical, Major, Minor, or Informational.	Major

      Table 4 Enterprise Project and Tag

      Parameter	Description
      Enterprise Project	Specifies the enterprise project that the alarm rule belongs to. Only users who have all permissions for the enterprise project can manage the alarm rule. For details about how to create an enterprise project, see Creating an Enterprise Project.
      Tag	Specifies a key-value pair. Tags identify cloud resources so that you can easily categorize and search for your resources. You are advised to create predefined tags in TMS. For details, see Creating Predefined Tags. If your organization has configured tag policies for Cloud Eye, follow the policies when configure Tag for an alarm rule. If you add a tag that does not comply with the tag policies, alarm rules may fail to be created. Contact your administrator to learn more about tag policies. A key can contain up to 128 characters, and a value can contain up to 225 characters. You can create up to 20 tags.

   5. Click Create.

After the alarm rule is created, if the metric data reaches the specified threshold, Cloud Eye immediately informs you that an exception has occurred.
