This topic describes how to create threshold-based alert rules for a physical connection in a Cloud Enterprise Network (CEN) instance. CEN is integrated with Cloud Monitor of Alibaba Cloud. You can use the CEN console to navigate to the Cloud Monitor console and create threshold-based alert rules for the physical connection. This allows you to monitor the resource usage of the physical connection and avoid business disruption caused by resource exhaustion.


  1. Log on to the CEN console.
  2. In the left-side navigation pane, click Health Check.
  3. Select the region of the virtual border router (VBR) to which the physical connection is established and click Set Alarm in the Monitor column.
  4. On the Create Alarm Rule page, configure alert rules and click Confirm.
    You can create alert rules based on your business requirements. Supported parameters are: latency, packet loss rate, inbound bandwidth, and outbound bandwidth. You can specify a threshold value that triggers the alert based on your business requirements. For more information, see Create a threshold-triggered alert rule.
