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.
