A receiver is the final destination for receiving and delivering alerts. When the route collects an alert, a receiver delivers the alert to relevant personnel for further processing.

Alerts will be delivered by mail. To deliver the notification, configure an SMTP server and related settings, including the mailbox addresses of the sending and receiving ends, etc.

Through this combination model, users can flexibly configure the alarm system and customize alarms based on resource usage and performance indicators. For example, when CPU or memory usage exceeds a set threshold, the system can automatically trigger an alert and notify the user via email. Send appropriate alarm information to corresponding processing personnel according to different needs.

Important!

It is recommended to set alarm configuration through EonOne. The settings on EonOne will be synchronized to EonKube. However, the alarm configurations set on EonKube will not be synced to EonOne.
