Enabling Alarm Notifications

This topic describes how to enable notifications for attack logs. Once this function is enabled, WAF sends you SMS or email notifications if an attack is detected.

You can configure certificate expiration reminders. When a certificate is about to expire, WAF notifies you by the way you configure, such as email or SMS.

  • Before you set alarm notification, create a message topic in the SMN service.
  • If you have enabled enterprise projects, ensure that you have all operation permissions for the project where your WAF instance locates. Then, you can select the project from the Enterprise Project drop-down list and enable alarm notifications.

Prerequisites

SMN has been enabled.

Constraints

  • Alarm notifications are sent if the number of attacks reaches or exceeds the threshold configured for a certain period.

  2. Click in the upper left corner of the management console and select a region or project.
