Setting Alarm Rules

Scenarios

You can set alarm rules to customize the monitored objects and notification policies and keep track of the RDS running status.

The RDS alarm rules include alarm rule names, services, dimensions, monitored objects, metrics, alarm thresholds, monitoring period, and whether to send notifications.

Setting Alarm Rules

2. Click in the upper left corner and select a region and a project.
3. Click Service List. Under Management & Governance, click Cloud Eye.
4. In the navigation pane on the left, choose Cloud Service Monitoring > Relational Database Service.

   Table 1 Alarm rule information

   Parameter	Description
   Name	Alarm rule name. The system generates a random name, which you can modify.
   Description	Description about the rule.
   Method	There are three options: Associate template, Use existing template, and Configure manually. NOTE: If you select Associate template, after the associated template is modified, the policies contained in this alarm rule to be created will be modified accordingly. You are advised to select Use existing template. The existing templates already contain three common alarm metrics: CPU usage, memory usage, and storage space usage.
   Template	Select the template to be used. You can select a default alarm template or create a custom template.
   Alarm Policy	Policy for triggering an alarm. 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. 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 is triggered.
   Alarm Severity	The alarm severity can be Critical, Major, Minor, or Informational.

   Table 2 Alarm notification

   Parameter	Description
   Alarm Notification	Whether to notify users when alarms are triggered. Notifications can be sent by email, text message, or HTTP/HTTPS message.
   Notification Recipient	You can select a notification group or topic subscription as required.
   Notification Group	Notification group the alarm notification is to be sent to.
   Notification Object	Object the alarm notification is to be sent to. You can select the account contact or a topic. The 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.
   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 within 08:00-20:00.
   Trigger Condition	Condition for triggering an alarm notification. You can select Generated alarm (when an alarm is generated), Cleared alarm (when an alarm is cleared), or both.
   Enterprise Project	Enterprise project that the alarm rule belongs to. Only users with the enterprise project permissions can view and manage the alarm rule.
   Tag	A tag is a key-value pair. Tags identify cloud resources so that you can easily categorize and search for your resources.

7. Click Create. The alarm rule is created.
