Setting Alarm Rules

Updated on 2024-10-14 GMT+08:00

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

  1. Log in to the management console.
  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.

    Figure 1 Choosing a monitored object

  5. Locate the DB instance for which you want to create an alarm rule and click Create Alarm Rule in the Operation column.

    Figure 2 Creating an alarm rule

  6. On the displayed page, set parameters as required.

    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.

    Figure 3 Configuring alarm notification
    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.

    For details about how to create alarm rules, see Creating an Alarm Rule in the Cloud Eye User Guide.
