This topic describes how to configure an alert rule for Anti-DDoS Pro or Anti-DDoS Premium in the CloudMonitor console. After alert rules are configured, CloudMonitor notifies you of exceptions in traffic and connections on the IP addresses of your Anti-DDoS Pro or Anti-DDoS Premium instances. This allows you to handle exceptions and restore workloads at the earliest opportunity.
