   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 select All Resources, the system generates an alert when a VBR that belongs to the current Alibaba Cloud account meets the specified condition. If you select 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 select 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 Rules. In the Add Rule Description panel, specify the rule name, metric type, metric, threshold, alert level, and notification method. Click OK.
   Mute For	Specify the interval at which CloudMonitor resends alert notifications before the alert is cleared. An alert is triggered when the condition of an alert rule is met. CloudMonitor does not resend an alert notification if the alert is triggered again within the mute period. If the alert is not cleared after the mute period ends, CloudMonitor resends alert notifications. Note You can click Advanced Settings to set this parameter.
