If multiple resources in your Alibaba Cloud account trigger the same alert rule within a single cycle, Cloud Monitor consolidates the notifications to reduce alert fatigue and resource usage. After the initial alert, subsequent consolidated notifications are sent at one-minute intervals.
Notification methods
Notification consolidation applies to email and DingTalk chatbot notifications. Each consolidated email or message displays details for up to 20 resources.
