Creating Alarm Rules

Scenarios

You can set NAT gateway alarm rules to customize the monitored objects and notification policies. Then, you can learn NAT gateway running status in a timely manner.

Procedure

1. Log in to the management console.
2. Under Management & Deployment, select Cloud Eye.
3. In the left navigation pane, choose Alarm Management > Alarm Rules.
4. On the Alarm Rules page, click Create Alarm Rule and set required parameters to create an alarm rule, or modify an existing alarm rule.
5. On the Create Alarm Rule page, follow the prompts to configure the parameters.
   1. Set the alarm rule name and description.

      Table 1 Configuring the alarm rule name and description

      Parameter	Description
      Name	Specifies the alarm rule name. The system generates a random name, which you can modify. Example value: alarm-b6al
      Description	(Optional) Provides supplementary information about the alarm rule.

   2. Select an object to be monitored 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.	NAT Gateway
      Dimension	Specifies the metric dimension of the selected resource type.	Public NAT Gateway
      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
      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 customize a 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 raw data of the SNAT connections of the monitored object is 8000 or more for three consecutive 1-minute periods.	-
      Alarm Severity	Specifies the alarm severity, which can be Critical, Major, Minor, or Informational.	Major

   3. Configure the 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 the Cloud Eye User Guide.
      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.

6. After the parameters are set, click Create.

   After the alarm rule is set, the system automatically notifies you when an alarm is triggered.
