      Statistical Granularity and Time Span

      The supported time span varies by statistical granularity. When pulling monitoring data, you should pay attention to the time span restrictions as detailed below:
      Statistical Granularity
      Maximum Time Span (End Time - Start Time)
      60s
      12 hours
      300s
      3 days
      3600s
      30 days
      86400s
      186 days
