Creating an Alarm Rule

Scenarios

Functions

• Alarm rules can be created for all monitoring items on Cloud Eye.
• Alarm rules can be created for all resources, resource groups, log monitoring, and custom monitoring.
• You can set notification windows of alarm rules, that is, customize the time when alarm rules are applied.
• Notifications can be sent by email, SMS message, or HTTP/HTTPS message.

Procedure

1. Log in to the management console.
2. Click Service List in the upper left corner and select Cloud Eye.
3. In the navigation pane on the left, choose Alarm Management > Alarm Rules, and click Create Alarm Rule in the upper right corner.
4. On the Create Alarm Rule page, configure the parameters.
   1. Configure the alarm rule name and description.

      Table 1 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 a monitored object and configure alarm content parameters.

      Table 2 Parameters

      Parameter	Description	Example Value
      Alarm Type	Specifies the alarm type to which the alarm rule applies. The value can be Metric or Event.	Metric
      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, click Select Specific Resources and select resources.	Specific resources
      Group	This parameter is mandatory when Monitoring Scope is set to Resource groups.	N/A
      Method	There are two options: Use template or Configure manually.	Configure manually
      Template	Specifies the template to be used. You can select a default or a custom alarm template.	ECS Alarm Template
      Alarm Policy	Specifies the policy for triggering an alarm. If you set Resource Type to Custom Monitoring or a specific cloud service, whether an alarm will be triggered 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 to Event Monitoring, the event that triggers an alarm is an instant operation. For example, if event improper ECS running occurs, Cloud Eye triggers an alarm. 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
      Mount Point or Disk	This parameter is displayed on the console and can be configured only when the following conditions are met: The monitoring scope is Resource groups or Specific resources. Resource Type: ECSs or BMSs Method : Configure manually. Metric Name in an alarm policy: disk metric whose name is prefixed with Agent For the Windows OS, enter a drive letter, such as C, D, or E. For the Linux OS, enter a mount point, such as /dev or /opt.	/dev
      Alarm Severity	Specifies the alarm severity, which can be Critical, Major, Minor, or Informational.	Major

   3. Configure the alarm notification.

      Table 3 Parameters for configuring alarm notifications

      Parameter	Description
      Alarm Notification	Specifies whether to notify users when alarms are triggered. Notifications can be sent by email, SMS message, or HTTP/HTTPS message.
      Notification Object	Specifies the object to which alarm notifications will be sent. You can select the account contact or a topic. The account contact is the tenant owner. If a user registers both a mobile number and an email address, they will receive alarm information through both channels. However, if only one of these contact methods is registered, the alarm information will be sent exclusively to that registered one. A topic is a specific event type for publishing messages or subscribing to notifications. If the required topic is not available, create one and add subscriptions to it first. For details, see Creating a Topic and Adding Subscriptions.
      Notification Window	Cloud Eye sends notifications only within the notification window specified in the alarm rule. If Notification Window is set to 08:00-20:00, Cloud Eye sends notifications only from 08:00 to 20:00.
      Trigger Condition	Specifies the condition for triggering an alarm notification. If Alarm Type is set to Metric, you can select Generated alarm, Cleared alarm, or both. If Alarm Type is set to Event, you can select Generated alarm only.
