This topic describes how to use CloudMonitor to monitor transit routers. You can create threshold-triggered alert rules to be notified of anomalies in data transmission over transit routers.
Limits
Only Enterprise Edition transit routers support monitoring.
View the monitoring data of a transit router
Log on to the CEN console.
On the Instances page, click the ID of the CEN instance that you want to manage.
On the tab, find the transit router that you want to manage and click the
icon in the Monitoring column. In the Monitoring panel, view the monitoring data of the transit router.
By default, the monitoring data of the last hour is displayed. Each data point represents the average value within the minute.
You can query monitoring data within the last 3 hours, 6 hours, 12 hours, 1 day, 7 days, and 30 days, or a custom time period. You can also set the Interval parameter to query monitoring data that is collected at a specified interval.
The monitoring data is dynamically updated.
On the top of the Charts tab, turn on Auto Refresh to enable the system to automatically update the monitoring data every minute.
Metric
Description
Inbound Traffic Rate

Outbound Traffic Rate
The data transfer rate from the transit router to the network instance. Unit: bit/s.
Inbound Packet Rate
The packet forwarding rate from the network instance to the transit router. Unit: pps.
Outbound Packet Rate
The packet forwarding rate from the transit router to the network instance. Unit: pps.
Inbound Bytes
The byte transfer rate from the network instance to the transit router. Unit: bytes.
Outbound Bytes
The byte transfer rate from the transit router to the network instance. Unit: bytes.
Inbound Packets
The number of packets that the transit router receives from the network instance. Unit: packets.
Outbound Packets
The number of packets that the transit router sends to the network instance. Unit: packets.
NoteYou can also navigate to the Charts tab to view the monitoring data of the transit router. For more information, see View the monitoring data of transit routers.
Create a threshold-triggered alert rule for a transit router
Log on to the CEN console.
On the Instances page, click the ID of the CEN instance that you want to manage.
On the tab, find the transit router that you want to manage and click Set Alarm in the Monitoring column.
In the Add Rule Description panel, set the parameters and click OK.
The following table describes the parameters that are related to this topic. For more information about how to configure other parameters, see Create an alert rule.
Parameter
Description
