Express Connect integrates with CloudMonitor to provide monitoring and alerts for QoS queues. This feature lets you detect the status of QoS queues in real time and receive alert notifications based on the alert rules that you configure. This helps you monitor QoS queues more effectively and ensure that resource allocation aligns with your policies.
Prerequisites
You can associate QoS policies only with dedicated physical connection ports that have advanced Quality of Service (QoS) capabilities. QoS policies cannot be associated with shared physical connection ports or virtual border router (VBR) instances.
To use QoS policies, you must enable the outbound data transfer fee.
You have created a QoS policy and added queues to the policy.
View QoS queue monitoring information
Log on to the Express Connect console.
In the top menu bar, select the destination region.
In the navigation pane on the left, click QoS Policy. Click the target instance. On the Queues tab, in the Queue Details section, click the Monitoring icon to view the monitoring data.
By default, the system displays monitoring data collected within the last hour. You can select other time ranges from the Time drop-down list. Supported time ranges are 3 hours, 6 hours, and 12 hours. You can also select Custom to specify a custom time range.
After you enable Auto Refresh, the monitoring chart is updated every minute.
Configure QoS queue alert rules
Click the Monitoring icon. In the upper-right corner of the page, click Set Alert Rule.
In the Set Rule Description panel, select a metric type, configure parameters such as the metric threshold and alert level, and then click OK.
For more information about other configuration items for alert rules and how to set alert conditions using expressions, see Create an alert rule and Expressions for alert rules.
Simple Metric: Select a metric, and then set a threshold and an alert level for the metric.
Composite Metric: Select an alert level, and then configure a multi-metric alert description to set alert conditions for two or more metrics.
NoteIf you set a multi-metric alert rule, the target resource must have data for each metric. An alert is triggered only when the conditions for all metrics are met. For example, if a multi-metric alert rule includes the rate and packet loss of a QoS queue, an alert is not triggered if the packet loss does not exceed the specified threshold.
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-based alert rule.
NoteThe intelligent threshold feature is available only by invitational preview. To use this feature, you must submit a ticket.
QoS queue monitoring metrics
Metric | Description | MetricName | Statistics |
QoS queue rate | The data transfer rate of a QoS queue. Unit: bps | QosQueueRate | Value |
QoS queue packet loss | The number of packets that are dropped in a QoS queue per second. Unit: pps | QosQueueLossPkg | Value |
