      Note：

      • The statistical granularity (period) may vary by metric. You can call the DescribeBaseMetrics API to obtain the period supported by each metric.
      • The metric values of public network inbound packets (InPkg) and outbound packets (OutPkg) as well as public network inbound bandwidth (InTraffic) and outbound bandwidth (OutTraffic) are calculated as follows: for the ten-second statistical granularity, the metric value is the average value; for the one-minute granularity, the metric value is the maximum of the average values of every ten seconds; for the five-minute granularity, the metric value is the maximum of the average values of every minute; and so on.
