Event notifications

Background information

The event monitoring feature of CloudMonitor serves as a centralized platform that enables you to query system events generated for different Alibaba Cloud services and view event statistics. This allows you to monitor your Alibaba Cloud services. Event monitoring can send alert notifications when exceptions occur on your Alibaba Cloud services. You can also use event monitoring to automate exception handling. CloudMonitor is integrated into ROS. When the status of a stack changes, ROS sends an event notification to CloudMonitor. Then, CloudMonitor queries details about the event and sends alerts.
