   Table 1 Alarm rule information

   Parameter	Description
   Name	Alarm rule name. The system generates a random name, and you can change it if needed. The value can contain only letters, digits, underscores (_), and hyphens (-), and cannot exceed 128 characters.
   Description	Description of the alarm rule. The value can contain a maximum of 256 characters. This parameter is optional.
   Method	Mode for configuring an alarm policy. You can select Associate template or Configure manually. Configure manually: You can create a custom alarm policy as needed. Associate template: If the same alarm rule needs to be configured for multiple GaussDB instances, you can use an alarm template to simplify operation.
   Template	This parameter is only available if you select Associate template for Method. You can select a default alarm template or create a custom one. After an associated template is modified, the policies contained in this alarm rule to be created will be updated accordingly.
   Alarm Policy	This parameter is only available if you select Configure manually for Method. An alarm is triggered when the metric configured for this alarm reaches the preset threshold in consecutive periods. For example, an alarm is triggered if the average CPU usage is 80% or higher for three consecutive 5-minute periods. A maximum of 50 alarm policies can be added to an alarm rule. If any of these alarm policies is met, an alarm will be triggered.

   Table 2 Alarm notification

   Parameter	Description
   Alarm Notifications	Specifies whether to notify users when alarms are triggered. Notifications can be sent by email or text messages, or through HTTP/HTTPS requests to servers. This function is enabled by default.
   Notified By	The following three options are available: Notification policies: Flexible alarm notifications by severity and more notification channels are provided. Notification groups: Configure notification templates on the Cloud Eye console. Topic subscriptions: Configure notification templates on the Simple Message Notification (SMN) console.
   Notification Policies	This parameter is only available if you select Notification policies for Notified By. Select one or more notification policies. You can specify the notification group, window, template, and other parameters in a notification policy. For how to create a notification policy, see Creating, Modifying, or Deleting a Notification Policy.
   Notification Group	This parameter is only available if you select Notification groups for Notified By. Select the notification groups to which alarm notifications will be sent. For details about how to create a notification group, see Creating a Recipient and Notification Group.
   Recipient	This parameter is only available if you select Topic subscriptions for Notified By. You can select the account contact or a topic as the object to which alarm notifications will be sent. The account contact is the mobile phone number and email address of the registered account. A topic is a specific event type for publishing messages or subscribing to notifications. If the required topic is unavailable, create one first and add subscriptions to it. For details, see Creating a Topic and Adding Subscriptions.
   Notification Template	This parameter is only available if you select Notification groups or Topic subscriptions for Notified By. You can select an existing template or create a new one to send alarm notifications.
   Notification Window	This parameter is only available if you select Notification groups or Topic subscriptions for Notified By.

   Trigger Condition	This parameter is only available if you select Notification groups or Topic subscriptions for Notified By. You can select either Generated alarm or Cleared alarm, or both.
   Enterprise Project	Enterprise project that the alarm rule belongs to. Only users who have the permissions of the enterprise project can view and manage this alarm rule.
   Tags	Key-value pairs that you can use to easily categorize and search for cloud resources. You are advised to create predefined tags in Tag Management Service (TMS). If your organization has configured tag policies for Cloud Eye, you need to add tags to alarm rules based on tag policies. If a tag does not comply with the policies, an alarm rule may fail to be created. Contact your organization 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 add up to 20 tags.
