Optimized monitoring for inter-region connections - Cloud Enterprise Network

Beginning August 30, 2023, Cloud Enterprise Network (CEN) supports an optimized monitoring system for inter-region connections. After the optimization, more monitoring metrics are available for inter-region connections, bandwidth plans, and quality of service (QoS) queues.

Optimization details

QoS queues can be monitored. Monitoring metrics of inter-region connections and bandwidth plans are optimized, and more monitoring metrics are available. The following table describes the monitoring metrics before and after the optimization.

Some of the metrics are new and therefore no existing metrics are available for comparison.
"Deprecated" indicates that the metric will soon be phased out. The time when metrics will be phased out will be posted on the Alibaba Cloud site.
If you configured metrics by using the earlier version of the CEN console, you can continue using them. However, monitoring data will no longer be available after the metrics are phased out. To ensure smooth user experience, we recommend that you use the new metrics.

Bandwidth plan metrics

New metric	Metric description	Earlier-version metric	Earlier-version metric status
CENBandwidthPackagePeakBandwidthRate	Rate of Outbound Bandwidth: the peak bandwidth of the bandwidth plan. Unit: bit/s.	InternetOutRateByConnectionArea	Deprecated No longer available in the CEN console Renamed InternetOutRateByConnectionArea(deprecated)
CENBandwidthPackagePeakBandwidthRate	Average Rate of Outbound Bandwidth: the average bandwidth of the bandwidth plan. Unit: bit/s.	N/A
CENBandwidthPackagePeakBandwidthUtilization	Usage of Outbound Bandwidth: the percentage of the peak bandwidth to the maximum bandwidth of the bandwidth plan.
