Sending Event Alarms to WeCom

Updated on 2024-05-25 GMT+08:00

Overview

CAE can send notifications when instance scheduling, health check, image pull, volume mounting, or container startup succeeds or fails. By configuring event notification rules, you can learn about the component running status in a timely manner and quickly locate faults. The configuration of event notification rules depends on the AOM and SMN services. Component instance events are reported to AOM. You can choose Application O&M Management > Alarm Management > Alarm List > Events to view the reported events. SMN is the sender of alarm messages.

By default, CAE reports component instance events to AOM. After configuring event notification rules, CAE creates topics and subscribers in SMN, and creates alarm rules and alarm action rules in AOM.
