Configuring Event Alarm Rules

Scenarios

Event monitoring provides event data reporting, query, and alarm reporting. When there are specified events, you will receive alarm notifications and learn about the running status of your resources. You can set alarm rules for system and custom events. When a specified event occurs, Cloud Eye automatically sends an alarm notification. This helps you quickly identify and address issues.

Procedure

1. Log in to the Cloud Eye console.
2. In the navigation pane on the left, choose Event Monitoring.
3. Click Create Alarm Rule in the upper right corner.
   

   If you want to create an alarm rule for a specific event, locate the event in the event list and click Create Alarm Rule in the Operation column. On the Create Alarm Rule page, the required parameters have been configured for that event.

4. On the Create Alarm Rule page, configure basic information about the alarm rule.

   Table 1 Basic parameters

   Parameter	Description
   Name	Name of the alarm rule. The system already generates a random name. You can modify it. The rule name can contain up to 128 characters. Only letters, digits, underscores (_), and hyphens (-) are allowed.
   Description	(Optional) Alarm rule description. It can contain up to 256 characters.

5. Select an object to be monitored and set alarm parameters.

   Alarm Type	Alarm type that the alarm rule applies to. The default value is Event.

   Event Source	Name of the cloud service that triggers the event. For a custom event, set Event Source to the value of event_source.

   Template	If you set Method to Associate template, you need to select a template. You can select a default or custom template.
   Event Name	A phrase that briefly describes an instantaneous operation triggering an alarm, such as login and logout. For a custom event, the event name is the value of event_name when the custom event is reported.

   Table 3 Alarm notification parameters

   Parameter	Description
   Alarm Notifications	Whether to send alarm notifications by SMS, email, FunctionGraph (function), FunctionGraph (workflow), WeCom, DingTalk, Lark, WeLink, HTTP, or HTTPS. This parameter is enabled by default.
   Notified By	Notification method. The following options are available: Notification groups: A notification group includes one or more notification channels for sending notifications to specified recipients. For details, see Creating a Recipient and Notification Group. Topic subscriptions: You need to select recipients for alarm notifications. You can select either the account contact or a custom topic created in SMN. NOTE: Cloud Eye uses SMN for alarm notifications. If SMN has major delays, the alarm notifications may also be delayed.
   Notification Group	If Notified By is set to Notification groups, you need to select the notification group to which alarm notifications will be sent. 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. 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. 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 Creating a Topic and Adding Subscriptions.
   Notification Window	Cloud Eye sends notifications only within the notification window specified in the alarm rule. If the notification window is set to 08:00-20:00, notifications are sent only within this specified time range.
   Time Zone	Time zone for the alarm notification window. By default, it matches the time zone of the client, but can be manually configured.
