Resource monitoring and alerting rules track key metrics in your cloud environment, such as CPU utilization, memory usage, and network traffic. When a metric meets a trigger condition, the system automatically runs a predefined template to perform O&M actions to help maintain resource stability and security.
Prerequisites
You have created a template. For more information, see Template overview.
