Creating an Alarm Rule

The alarm function provides the alarm service for monitoring data. By creating alarm rules, you can define how the alarm system checks monitoring data and sends alarm notifications when monitoring data meets alarm policies. Alarm rules for important metrics help you timely know metric data exceptions and quickly rectify the faults.

If you disable Alarm Notification when creating an alarm rule, no alarm notification will be sent. You can view the status changes of alarm rules using the alarm records function of Cloud Eye.

This section describes how to create alarm rules for metrics and events.

Creating an Alarm Rule for Metric Monitoring

Log in to the management console.
In the upper left corner, select the desired region.
Click Service List. Under Management & Governance, click Cloud Eye.
In the navigation pane on the left, choose Alarm Management > Alarm Rules.
On the displayed Alarm Rules page, click Create Alarm Rule and configure required parameters.
- Alarm Type: The type of the alarm that the alarm rule applies to. Select Metric.
- Cloud Product: The name of the service for which the alarm rule is configured. Select Cloud Phone Host - Cloud Phone Servers.

Alarm Notifications	Whether to send alarm notifications by SMS, emailFunctionGraph (function), FunctionGraph (Workflow), WeCom, DingTalk, Lark, WeLink or HTTP or HTTPS. This parameter is enabled by default.
Notified By	Notification method. You can select Notification groups, or Topic subscriptions. Notification groups: You need to create notification recipients and add them to a notification group. Topic subscriptions: You can select a cloud account contact or a custom topic created in SMN.
Notification Group	Notification group that alarm notifications will be sent to. For details about how to create a notification group, see Creating a Recipient and Notification Group.
Recipient	Target recipient of alarm notifications. You can select the account contact or a topic name. This parameter is available only if Notified By is set to Topic subscriptions. If there is a display name of a topic, the format is Topic name (display name), and you can search for a topic by name or display name. If no display name is set for a topic, only the topic name will be displayed. The account contact is the mobile phone number and email address of the registered account.

Enterprise Project	Enterprise project that the alarm rule belongs to. Only users with the enterprise project permissions can manage the alarm rule. To create an enterprise project, see Creating an Enterprise Project.
Tag	Each tag is a key-value pair. You can tag cloud resources to easily categorize and search for them. You can create tags using TMS. For details, see Creating Predefined Tags.
