Enabling Alarm Notifications for DDoS Attacks

After you enable the alarm notification, a notification message will be sent to you through the method you have configured when:

  • An IP address is under the DDoS attacks.
  • Additional fees are incurred for traffic exceeding the basic protection bandwidth.

If you want to monitor service metrics in detail, you are advised to use Cloud Eye to set alarm rules and alarm notifications. For details, see Viewing Monitoring Metrics.

Prerequisites

  • The Simple Message Notification (SMN) service is a paid service. For details about the price, see SMN Product Pricing Details.
  • Before enabling alarm notifications, you are advised to create a message topic in the SMN service as an administrator. For details, see .
