You can view monitoring information about an Express Connect circuit associated with a virtual border router (VBR) by using CloudMonitor and the health check feature of Cloud Enterprise Network (CEN). Monitoring information includes outbound bandwidth, inbound bandwidth, network latency, and packet loss rate. This topic describes how to view monitoring information about an Express Connect circuit on the Health Check page of the CEN console.

Background information

Before you view monitoring information about an Express Connect circuit, take note of the following limits:
  • After you associate a VBR with a transit router, the system displays the inbound and outbound bandwidth of the Express Connect circuit by default.
  • Before you can view information about network latency and packet loss rate of an Express Connect circuit, you must configure health checks for the Express Connect circuit. For more information, see Manage health checks.

View monitoring information about an Express Connect circuit

  1. Log on to CEN console.
  2. In the left-side navigation pane, click Health Check.
  3. On the Health Check page, select the region where the VBR is deployed.
  4. Find the health check configuration and click Monitor in the Monitor column to view monitoring information about the Express Connect circuit.

    By default, the system displays monitoring data collected within the last hour. You can also choose to view monitoring data collected within the last 3 hours, 6 hours, 12 hours, or the last day by selecting an option from the drop-down list in the upper-left corner of the Monitoring page. You can also specify a custom time period.

    • Outbound Bandwidth: the bandwidth that is used to transmit data from Alibaba Cloud to the data center. Default unit: bit/s.

      You can select Kbit/s, Mbit/s, or Gbit/s from the drop-down list next to a monitored item.

    • Inbound Bandwidth: the bandwidth that is used to transmit data from the data center to Alibaba Cloud. Default unit: bit/s.

      You can select Kbit/s, Mbit/s, or Gbit/s from the drop-down list next to a monitored item.

    • Latency: the network latency between Alibaba Cloud and the data center. Unit: milliseconds.
    • Packet Loss Rate: the packet loss rate of communication between Alibaba Cloud and the data center.
    Note You can also view monitoring information about the Express Connect circuit on the Charts tab. For more information, see View monitoring information about an Express Connect circuit.

Create a threshold-based alert rule for the Express Connect circuit

  1. Log on to CEN console.
  2. In the left-side navigation pane, click Health Check.
  3. On the Health Check page, select the region where the VBR is deployed. Find the health check configuration and click Set Alarm in the Monitor column.
  4. On the Alert Rules page, click Create Alert Rule.
  5. On the Create Alert Rule page, set Product to CEN-Router, set other parameters based on your requirements, and then click OK.
    You can configure a threshold-based alert rule by specifying a threshold value for latency, packet loss rate, inbound bandwidth, or outbound bandwidth. For more information, see Create a threshold-triggered alert rule.
