CloudMonitor provides multiple monitoring metrics for NAT Gateway, including the SNAT connections to help you monitor network usage of the NAT Gateway service and set alarm rules for the monitoring metrics. After you purchase the NAT gateway service, CloudMonitor automatically collects data on the preceding monitoring metrics.

Alarm service

  • Parameter descriptions
    • Monitoring metrics: The monitoring metrics provided by the NAT Gateway service.
    • Statistical cycle: The alarm system checks whether your monitoring data has exceeded the alarm threshold based on the cycle.  For example, if the statistical cycle of the alarm rule for memory usage is set to one minute, the system checks whether the memory usage has exceeded the threshold value every other minute.
    • Consecutive times: An alarm is triggered when the value of the monitoring metrics continuously exceeds the threshold value for the set consecutive cycles.
