Configuring Monitoring Alarm Rules
You can set alarm rules to customize the monitored objects and notification policies, and set parameters such as the alarm rule name, monitored object, metric, threshold, monitoring scope, and whether to send notifications. This helps you learn the CNAD protection status in a timely manner.
For details about how to set monitoring alarms for multiple instances or protected IP addresses, see Setting Monitoring Alarm Rules in Batches. For details about how to set monitoring alarms for a specified instance or protected IP address, see Setting Monitoring Alarm Rules for a Specified Resource.
If you need to customize more metrics, you can report them to Cloud Eye through API requests. For details, see Adding Monitoring Data and Metrics.
