Overview

Alarm reporting is an essential aspect of observability. In addition to traditional resource usage alarms (such as CPU and memory usage alarms), there are custom monitoring metric alarms (such as container restart alarms and application access failure alarms).

CCE works with AOM for metric and event alarm reporting and provides Alarm Center that allows you to quickly configure and view common alarms (such as resource usage alarms).

Figure 1 Alarm Center architecture

• Alarm Center

  Based on the alarm capabilities of AOM, Alarm Center provides quick alarm search and configuration for clusters. You can use Alarm Center to configure common alarm rules with just a few clicks.

• AOM

  AOM is a one-stop, multi-dimensional O&M management platform for monitoring and alarm reporting of cloud applications.

• Simple Message Notification

  Simple Message Notification (SMN) connects cloud applications. After events or alarms are triggered, SMN will send notifications. In cloud native scenarios, alarms triggered by AOM are sent by SMS message, email, or HTTP message configured on SMN.
