You can set alarms for NAT gateways to monitor the status of NAT gateways.
Log in to the Cloud Monitor console.
In the directory on the left, select Alarm Configuration > Alarm Policy to enter the alarm policy configuration page, and click Create.
Enter the name of the alarm policy, select NAT Gateway as the policy type, select the alarm object, set the alarm policy, select the alarm receiving group and alarm channel, and click Complete. You can view the set alarm policy in the alarm policy list.
Note:
After an alarm policy is created, you need to unbind all resources before you can delete it.
Viewing an Alarm Message
When an alarm condition is triggered, you will receive an alarm through the selected alarm channel (SMS/email/message center), or you can click Alarm History in the left directory to view it.
