	//   this statistic to determine the total volume of a metric.
	//
	//   - Average - The value of Sum / SampleCount during the specified period. By
	//   comparing this statistic with the Minimum and Maximum values, you can
	//   determine the full scope of a metric and how close the average use is to the
	//   Minimum and Maximum values. This comparison helps you to know when to increase
