2. In the top navigation bar, select a region. In the left-side navigation pane, click Virtual Border Routers (VBRs).

3. On the Virtual Border Routers (VBRs) page, find the VBR that you want to manage and click the icon in the Monitor column.

4. Click Set Alert Threshold in the upper-right corner of the Monitor panel.

5. On the Alert Rules page, click Create Alert Rule.

6. In the Create Alert Rule panel, set the following parameters and click OK.

   The following table describes the parameters that are related to this topic. For more information about other parameters, see Create an alert rule.

   Parameter	Description
   Product	Select the type of resource that you want to monitor by using CloudMonitor. In this example, Express Connect - VBR is selected.
   Resource Range	Specify the resources to which the alert rule is applied. If you specify All Resources, the system generates an alert when a VBR that belongs to the current Alibaba Cloud account meets the specified condition. If you specify Application Group and select an application group from the Associated Resources drop-down list, the system generates an alert when a VBR that belongs to the application group meets the specified condition. If you specify Instance and select the region and ID of a VBR from the Associated Resources drop-down list, the system generates an alert only when the selected VBR meets the specified condition.
   Rule Description	Specify the condition of the alert rule. An alert is triggered when the condition of the alert rule is met. To specify a condition, perform the following operations: Click Add Rule. In the Configure Rule Description panel, enter a rule name in the Alert Rule field and configure the Metric Type parameter. Valid values of the Metric Type parameter: Simple Metric: Select a metric and set the threshold and alert level for the metric. Combined Metrics: Select an alert level and specify alert conditions for two or more metrics in the Multi-metric Alert Condition section. Note If a multi-metric alert rule is configured, the desired resource must have data on each metric. An alert can be triggered only if the related conditions are met. For example, if a multi-metric alert rule includes Internet metrics but the ECS instance is not configured with an elastic IP address (EIP), alerts cannot be triggered. Expression: Select an alert level and then configure an alert expression. Dynamic Threshold: For more information about dynamic thresholds, see Overview and Create dynamic threshold-triggered alert rules. Note The dynamic threshold feature is in invitational preview. To use the feature, you must submit a ticket. Click OK. Note For more information about how to specify complex alert conditions, see Alert rule expressions.
