CloudMonitor provides multiple metrics, such as the number of source network address translation (SNAT) connections, to help you monitor the status of Network Address Translation (NAT) Gateway. CloudMonitor also allows you to set alert rules for these metrics so that you can receive alerts when any exception occurs.

After you purchase NAT Gateway, CloudMonitor automatically collects data based on these metrics.
