This topic describes how to use the custom event alert feature. This feature allows you to receive alert notifications for custom events in a timely manner and automate the handling process.

Background information

CloudMonitor can notify you of custom events that are reported when exceptions occur. CloudMonitor supports the following notification methods for custom events:
  • Sends alert notifications to you by using emails or DingTalk chatbots.
  • Pushes alert notifications to the specified callback URL. Then, you can automate the handling process based on your scenario.
