   Table 2 Alarm rule parameters

   Parameter	Description	Example Value
   Alarm Type	Alarm type to which the alarm rule will apply. The type can be Metric or Event. For details about how to select an alarm type, see Table 1.	Metric
   Cloud Product	Select the cloud product you want to monitor. This parameter is only available if you select Metric for Alarm Type. For details about supported cloud products and their metrics, see Cloud Product Metrics.	Elastic Cloud Server - ECSs
   Resource Level	Resource level of the monitored object. This parameter is only available if Alarm Type is set to Metric. The value can be Cloud product (recommended) or Specific dimension. Take ECS as an example. ECSs is the cloud product. Specific dimensions are disks, mount points, processes, and more. NOTE: If you select Cloud product for Resource Level, metrics across dimensions (such as Disk Usage and CPU Usage) can be configured in the same alarm rule. If you select Specific dimension, only metrics of the specified dimension can be configured for the same alarm rule	Cloud product
   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. To exclude resources that do not need to be monitored, click Select Resources to Exclude. Resource groups: An alarm will be triggered if any resource in the selected resource group meets the alarm policy. To exclude resources that do not need to be monitored, click Select Resources to Exclude. Specific resources: Click Select Specific Resources next to Instance to select resources. NOTE: If Alarm Type is set to Metric, you can select Resource groups, All resources, or Specific resources. If Alarm Type is set to Event and Event Type is set to System event, you can configure the monitoring scope. Currently, Resource groups is only available for DDS, RDS, and DCS event alarms.	Specific resources
   Group	When Monitoring Scope is set to Resource groups, you need to select a group. If no resource group meets you needs, click Create Resource Group to create one. After selecting a resource group from the drop-down list, you can click View Resources in a Group to view the details of resources in the group. After an alarm rule is configured, the group cannot be modified.	N/A
   Instance	When Monitoring Scope is set to Specific resources, you need to select the monitored objects for the alarm rule. Click Select Specific Resources to select desired resources.	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 Alarm Type is set to Event. You can select either System event or Custom event. For details about the events supported by each cloud service, see Events Supported by Event Monitoring.	System event
   Event Source	This parameter is only available if Alarm Type is set to Event. If Event Type is set to System event, select the cloud service from which the event comes. If Event Type is set to Custom event, the event source must be the same as that of the reported source and is written in the service.item format. For details about how to report an event, see Reporting Events.	Elastic Cloud Server
   Method	Select a method for configuring an alarm rule. For metric alarm rules or system event alarm rules, you can customize a policy or use a preset template to create one. For custom event alarm rules, you can only customize a policy. Configure manually: You can create a custom alarm policy as needed. Associate template: If the same alarm rule needs to be configured for multiple groups of resources under the same cloud product, you can use an alarm template to simplify operations.	Configure manually
   Template	If Method is set to Associate template, you need to select a template. You can select a default or custom template. NOTE: An alarm template may contain alarm policies of multiple cloud products or different dimensions of the same cloud product. When you create an alarm rule, the alarm policies vary according to the resource level. If Resource Level is set to Cloud product, all alarm policies of the cloud product in the alarm template will be synchronized to the alarm rule. If Resource Level is set to Specific dimension, alarm policies of the same dimension as the current resource in the alarm template will be added to the alarm rule.	N/A
   Alarm Policy	If you select Configure manually for Method, you need to configure alarm policies. 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, Cloud Eye triggers an alarm if the average CPU usage of the monitored object is 80% or more for three consecutive 5-minute periods. If you set Alarm Type is to Event and a specified event occurs, an alarm is triggered. For example, an alarm is triggered if a VM is restarted. For details about alarm policy parameters, see Alarm Policies. You can add up to 50 alarm policies for a single alarm rule. You can choose to send alarm notifications when any of the policies is met or when all policies are met.	N/A
   Alarm Severity	Alarm severity, which can be Critical, Major, Minor, or Informational.	Major

7. Configure parameters for alarm notifications.
   Figure 3 Configuring alarm notifications
   

   Table 3 Parameters for configuring alarm notifications

   Parameter	Description	Example Value
   Alarm Notification	Whether to send alarm notifications by SMS, emailFunctionGraph (function), FunctionGraph (Workflow), WeCom, DingTalk, Lark, WeLink or HTTP or HTTPS. This parameter is enabled by default.	Enabled
   Notified By	Notification method. You can select Notification groups, or Topic subscriptions. Notification groups: You need to create notification recipients and add them to a notification group. Topic subscriptions: You can select a cloud account contact or a custom topic created in SMN. NOTE: Cloud Eye uses SMN for alarm notifications. If SMN has major delays, the alarm notifications may also be delayed.	Notification groups
   Notification Group	If Notified By is set to Notification groups, you need to select the notification group to which alarm notifications will be sent. For details about how to create a notification group, see Creating a Recipient and Notification Group.	N/A
   Recipient	Target recipient of alarm notifications. You can select the account contact or a topic name. This parameter is available only if Notified By is set to Topic subscriptions. If there is a display name of a topic, the format is Topic name (display name), and you can search for a topic by name or display name. If no display name is set for a topic, only the topic name will be displayed. Account contact: Enter the phone number and email address of the registered account. A topic is used to publish messages and subscribe to notifications. If there is no topic you need, create one first and add subscriptions to it. For details, see Creating a Topic and Adding Subscriptions.	Account contact
   Notification Window	This parameter is only available if you select Notification group or Topic subscription for Notification Recipient. Time window during which Cloud Eye sends notifications. For example, if the notification window is set to 08:00:00 to 20:00:00, notifications are sent only within this specified time range when a metric reaches the specified threshold or a specified event occurs.	08:00-20:00
   Time Zone	Time zone for the alarm notification window. By default, it matches the time zone of the client server, but can be manually configured.	(GMT+08:00) Beijing, Chongqing, Hong Kong, Urumqi, Kuala Lumpur, Singapore, Perth, Taipei, Irkutsk, Ulaanbaatar
   Trigger Condition	This parameter is only available if you set Notified By to Notification groups or Topic subscriptions. If Alarm Type is set to Metric, you can select Generated alarm, Cleared alarm, or both. When the alarm type is set to Event, you can only select Generated alarm for Trigger Condition.	Generated alarm

8. Set parameters in Advanced Settings.

   Table 4 Enterprise Project and Tag

   Parameter	Description
   Enterprise Project	Enterprise project that the alarm rule belongs to. Only users with the enterprise project permissions can manage the alarm rule. To create an enterprise project, see Creating an Enterprise Project.
   Tag	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.

9. 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.
