This topic describes how to monitor a VPN gateway by using CloudMonitor. You can also set threshold-triggered alert rules and monitor the traffic of a VPN gateway. When a threshold is breached, a notification is sent to you.
View the monitoring data about a VPN gateway
- Log on to the VPN gateway console.
In the top navigation bar, select the region in which the VPN gateway resides.
On the VPN Gateways page, find the VPN gateway that you want to manage and click its ID.
On the details page, click the Monitor tab to view the monitoring data.
By default, the system displays the monitoring data within the last hour. You can also select 3 hours, 6 hours, 12 hours, or specify a custom time range.
The system can automatically update monitoring data.
On the top of the Monitor tab, you can turn on Auto Refresh to enable the system to automatically update monitoring data every minute.
