Express Connect uses Cloud Monitor to provide monitoring and alerting for VBR-to-VPC connections. You can monitor the real-time status of a connection and receive alert notifications based on your configured rules. This helps you efficiently monitor the connection status and prevent failures from affecting your services.
Prerequisites
A VBR-to-VPC connection is created. For more information, see Create a VBR-to-VPC connection.
Before you configure an alert rule, create an alert contact or an alert contact group. For more information, see Create an alert contact or an alert contact group.
View monitoring information for a VBR-to-VPC connection
Log on to the Express Connect console.
In the top navigation bar, select the destination region. In the navigation pane on the left, choose .
On the VBR Connections page, find the target VBR-to-VPC connection, and then click the
icon in the Monitoring column to view the monitoring information.By default, monitoring data from the last hour is displayed. You can view data from the last 3, 6, or 12 hours. You can also click Custom to specify a custom period.
Configure alert rules for a VBR-to-VPC connection
You can configure alert rules for a VBR-to-VPC connection to receive alert notifications when the connection fails. This helps you quickly identify connection issues and prevent service disruptions.
Log on to the Cloud Monitor console.
In the navigation pane on the left, choose .
On the Alert Rules page, click Create Alert Rule.
In the Create Alert Rule panel, configure the following parameters and click OK.
Parameter
Description
Product
The cloud service that CloudMonitor can manage. In this topic, select Express Connect - Peering Connection.
Resource Range
The scope of resources to which the alert rule applies. Valid values:
All Resources: The alert rule applies to all existing and new resources of the specified cloud service.
Application Group: The alert rule applies to all existing and new resources within the specified application group.
Instance: The alert rule applies only to the specified resources of the cloud service.
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 Set Rule Description panel, enter a Rule Name, and then set the rule conditions.
Simple Metric: Select a metric, and then set a threshold and an alert level for the metric.
Composite Metric: Select an alert level and configure a multi-metric alert description to set conditions for two or more metrics.
NoteIf you create a multi-metric alert rule, the target resource must have data for each metric. An alert is triggered only after all conditions are met. For example, if a multi-metric alert rule includes a metric for the public network but the ECS host is not configured with a public IP address, the alert cannot be triggered.
Expression: Select an alert level, and then configure an alert expression.
Intelligent Threshold: For more information about intelligent thresholds, see Overview and Create an intelligent threshold alert rule.
NoteThe intelligent threshold feature is in invitational preview. To use this feature, you must submit a ticket to request access.
Click OK.
NoteFor more information about how to set complex alert conditions using expressions, see Alert rule expressions.
VBR-to-VPC connection metrics
Metric | Description | MetricName | Statistics |
Inbound traffic | The total inbound traffic received from the peer. Unit: Byte. | IntranetRX | Value |
Outbound traffic | The total outbound traffic sent to the peer. Unit: Byte. | IntranetTX | Value |
Inbound bandwidth | The average rate of inbound traffic received from the peer. Unit: bit/s. | ReceiveBandwidth | Value |
Outbound bandwidth | The rate of outbound traffic sent to the peer. Unit: bit/s. | TransportedBandwidth | Value |
Packet loss rate | The ratio of data packets dropped because the bandwidth limit of the VBR-to-VPC connection is exceeded to the total number of data packets transmitted over the connection. | RouterInterfaceLossRate | Maximum |
Packets dropped due to throttling | The total number of data packets that are sent to the peer and dropped due to throttling. Unit: pps. | RateLimitDropPps | Value |
RI health check packet loss rate | During a health check on the VBR-to-VPC connection between a VBR instance and a VPC-connected instance, this is the ratio of response packets that are not received to the total number of probe packets sent. Note This setting takes effect only when the health check feature is enabled.
| RouterInterfaceHealthyCheckLossRate | Value |
RI health check latency | During a health check on the VBR-to-VPC connection between a VBR instance and a VPC-connected instance, this is the time it takes to receive a response after a probe packet is sent. Unit: us Note This metric is available only after you enable the health check feature.
| RouterInterfaceHealthyCheckLatency | Value |
