Express Connect is integrated with CloudMonitor. You can view the status of Express Connect circuits updated in real time and configure alert rules. This helps you gain deep insights into Express Connect circuits and detect connectivity errors at the earliest opportunity to avoid service interruptions.

Prerequisites

View the status of Express Connect circuits

The status of Express Connect circuits is updated in real time to help you detect connectivity errors at the earliest opportunity.

  1. Log on to the Express Connect console.
  2. In the top navigation bar, select the region and click Exclusive Physical Connection in the left-side navigation pane.
  3. View the status of an Express Connect circuit in the Connection Status column.
    Notice The Connection Status column displays the actual status of an Express Connect circuit only after the installation of the Express Connect circuit and the payment are completed. Otherwise, the Connection Status column displays Down.
    • UP: The Express Connect circuit is active.

      You can configure alert rules for an Express Connect circuit only when the Connection Status column displays UP.

Configure alert rules

You can configure alert rules for an Express Connect circuit only when the Connection Status column displays UP. After you configure alert rules, the system generates alerts when the Express Connect circuit is down. This helps you detect connectivity errors at the earliest opportunity and avoid service interruptions.

Note The following procedure shows how to configure alert rules for an Express Connect circuit in the Express Connect console. For more information about how to configure alert rules for an Express Connect circuit in the CloudMonitor console, see Create a threshold-triggered alert rule.
  1. Log on to the Express Connect console.
  2. In the top navigation bar, select the region and click Exclusive Physical Connection in the left-side navigation pane.
  3. Find the ID of the Express Connect circuit that you want to manage and click Set Alert Threshold in the Connection Status column.
  4. On the ExpressConnect-PORT tab, click Create Alert Rule.
  5. On the Create Alert Rule page, configure an alert rule and click Confirm.
    Parameter Description
    Product The name of the service that you want to monitor by using CloudMonitor. ExpressConnect-PORT is selected in this example.
    Resource Range The resources to which you want to apply the alert rule.
    • If you select All Resources, the system generates alerts when it detects connectivity errors in Express Connect circuits that belong to the current Alibaba Cloud account.
    • If you select Instances, you must also specify the region and ID of an Express Connect circuit. The system generates alerts only when it detects connectivity errors in the specified Express Connect circuit.
    Alert Rule The name of the alert rule.
    Rule Description The content of the alert rule. An alert is triggered when the value of a property meets a condition.

    In this example, an alert is triggered when the value of PhysicalConnectionStatus meets the condition Status<1.

    Mute for The interval at which CloudMonitor resends alert notifications before the alert is cleared.

    An alert is triggered when the value of a property meets the condition of an alert rule. The system does not resend an alert notification when the alert is triggered again within the mute period. CloudMonitor starts to resend alert notifications if the alert is not cleared after the mute period ends.

    Effective Period The period of time during which the alert rule is effective. CloudMonitor monitors a resource and generates alerts only when the alert rule is effective.
    Notification Contact The contact group to which alert notifications are sent.
    Notification Methods

    The methods that are used to send alert notifications. You can send alert notifications only through emails and DingTalk messages.

    Auto Scaling If you select Auto Scaling, a specific scaling rule is triggered when an alert is generated. You must specify Region, ESS Group, and ESS Rule if you select this option.
    Log Service If you select Log Service, the alert information is written to Log Service when an alert is generated. You must specify Region, Project, and Logstore if you select this option.

    For more information, see Quick start.

    Email Remark The additional information that you want to include in each alert notification sent through an email.
    HTTP CallBack The publicly-accessible webhook URL. CloudMonitor pushes alert notifications to this URL through HTTP POST requests. For more information, see Use the alert callback feature to report threshold-triggered alerts.

View monitoring data of an Express Connect circuit

You can analyze the monitoring data of an Express Connect circuit collected within a specified time range.

  1. Log on to the Cloud Monitor console.
  2. In the left-side navigation pane, click Cloud products. On the page that appears, enter ExpressConnect-PORT into the search box, and then find and click ExpressConnect-PORT.
  3. On the PORT List tab, select the region where the Express Connect circuit is located, find the ID of the Express Connect circuit, and then click Monitoring Charts in the Actions column.

    By default, the system displays monitoring data collected within the last hour. You can select 3 hours, 6 hours, 12 hours, 1 day, 3 days, 7 days, or 14 days on the dashboard, or specify a custom time range.

    • If the status of the Express Connect circuit displays 1, it indicates that the Express Connect circuit is up.
    • If the status of the Express Connect circuit displays 0, it indicates that the Express Connect circuit is down.
