CNAD Event Metrics

Description

Cloud Eye enables event monitoring for protected EIPs and generates alarms for scrubbing, blocking, and unblocking events. This helps you learn about the protection status of CNAD in a timely manner.

After the event alarm notification function is enabled, you can view event details on the Event Monitoring page of the Cloud Eye console when an event occurs.
