// Summary:

// percentage can exceed 100 percent.

// Summary:
// A percentage counter that shows the active time of one or more components as

// Summary:
// A percentage counter that shows the active time of one or more components as

//
// Summary:
// An average counter that measures the time it takes, on average, to complete a

// time of the sample interval to the number of processes or operations completed
// during that time. This counter type measures time in ticks of the system clock.

// started and the time when this value is calculated.
ElapsedTime = 807666944,
//
// Summary:
// An average counter that shows how many items are processed, on average, during

// number of items processed during the last interval to the number of operations
// completed during the last interval.
AverageCount64 = 1073874176,
//
// Summary:
// A base counter that stores the number of sampling interrupts taken and is used

// is greater than zero before using it as the denominator in a calculation of SampleFraction.
