You can view monitoring information about physical connection associated with virtual border routers (VBRs) by using the health check feature of Cloud Monitor and Cloud Enterprise Network (CEN). Monitoring information includes outbound bandwidth, inbound bandwidth, latency, and packet loss rate. This topic describes how to view monitoring information about a physical connection on the Health Check page of the CEN console.

Prerequisites

The VBR has health checks configured. For more information, see Configure health checks.

Background information

CEN is integrated with Cloud Monitor to provide monitoring information about physical connections. Monitoring information includes outbound bandwidth, inbound bandwidth, latency, and packet loss rate. Before you view monitoring information about a physical connection, take note of the following limits:
  • After you associate a VBR with the physical connection, CEN displays the inbound and outbound bandwidth of the physical connection by default. For more information about how to view bandwidth information about physical connections, see View monitoring charts.
  • Before you can view information about latency and packet loss rate of the physical connection, you must configure health checks for the physical connection.

    After you configure health checks, you can view all monitoring information about the physical connection on the Health Check page. Monitoring information includes outbound bandwidth, inbound bandwidth, latency, and packet loss rate.

Procedure

  1. Log on to the 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 and click The Monitor icon in the Monitor column.
    By default, the system displays the monitoring information within the last hour. You can also view monitoring information within the last 3, 6, or 12 hours. In addition, you can specify a custom time period.
    • Outbound Bandwidth: the bandwidth that is used to transmit data from Alibaba Cloud to the data center. Unit: bit/s. This is the default unit.

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

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

      You can also select Kbit/s, Mbit/s, or Gbit/s from the drop-down list next to the 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. Unit: %.
