Creating an Alarm Rule

1. Log in to the management console.
2. Under Management & Deployment, select Cloud Eye.
3. In the navigation pane on the left, choose Alarm Management > Alarm Rules.
4. Click Create Alarm Rule in the upper right corner.
5. On the Create Alarm Rule page, follow the prompts to set the parameters.
   1. Set the alarm rule name and description.

      Table 1 Name and Description

      Parameter	Description

      Description	(Optional) Provides supplementary information about the alarm rule.
      Enterprise Project	Specifies the enterprise project the alarm rule belongs to. Only users with the enterprise project permissions can view and manage the alarm rule. For details about how to create an enterprise project, see Creating an Enterprise Project.

   2. Select a monitored object and set alarm rule parameters.

      Table 2 Parameters

      Parameter	Description	Example Value
      Resource Type	Specifies the type of the resource the alarm rule is created for.	Elastic Cloud Server
      Dimension	Specifies the metric dimension of the selected resource type.	ECSs
      Monitoring Scope	Specifies the monitoring scope the alarm rule applies to. You can select Resource groups or Specific resources. NOTE: If Resource groups is selected and any resource in the group meets the alarm policy, an alarm is triggered. If you select Specific resources, select one or more resources and click to add them to the box on the right.	Specific resources
      Select Group	This parameter is mandatory when Monitoring Scope is set to Resource groups.	-
      Threshold Type	For ECSs, you can select Static or Dynamic. The feature is only available in region CN South-Guangzhou. Static: Indicates the fixed value set in an alarm rule. If the fixed value is reached, an alarm is 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 is triggered.	Static
      Method	There are two options: Use template or Create manually.	Create manually
      Template	Specifies the template to be used. You can select a default alarm template or a custom template.	-
      Alarm Policy	Specifies the policy for triggering an alarm. If you set Resource Type to Website Monitoring, Log Monitoring, Custom Monitoring, or a specific cloud service, whether to trigger an alarm depends on whether the metric 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 Resource Type is to Event Monitoring, the event that triggers the alarm is an instant event. For example, if event improper ECS running occurs, Cloud Eye triggers an alarm.	-
      Alarm Severity	Specifies the alarm severity. Valid values are Critical, Major, Minor, and Informational.	Major

   3. Set Alarm Notification parameters.
      Figure 2 Alarm Notification
      

      Table 3 Alarm Notification parameters

      Parameter	Description
      Alarm Notification	Specifies whether to notify users when alarms are triggered. Notifications can be sent by email, text message, or HTTP/HTTPS message.
      Notification Object	Specifies the object that receives alarm notifications. You can select the account contact or a topic. Account contact is the mobile phone number and email address of the registered account. A topic is used to publish messages and subscribe 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.
      Validity Period	Cloud Eye sends notifications only within the validity period specified in the alarm rule. If Validity Period is set to 08:00-20:00, Cloud Eye sends notifications only within 08:00-20:00.
      Trigger Condition	Specifies the condition for triggering the alarm notification. You can select Generated alarm (when an alarm is generated), Cleared alarm (when an alarm is cleared), or both.

   4. 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.
