Event notification

Background information

The event monitoring feature of Cloud Monitor serves as a centralized platform that allows you to query system events generated for different Alibaba Cloud services and view event statistics. This allows you to track the use of Alibaba Cloud services. When exceptions occur on Alibaba Cloud services, event monitoring allows you to receive alert notifications and handle the exceptions in an automated process. Cloud Monitor is integrated into ROS. When the status of a stack changes, ROS sends an event notification to Cloud Monitor. Then, Cloud Monitor queries details about the event and sends alerts.

For more information about system events, see the following topics:

• Cloud product system event monitoring
• Use the system event alert feature
