      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.

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 validity period 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. You can select Generated alarm (when an alarm is generated), Cleared alarm (when an alarm is cleared), or both.
