    ' PERF_AVERAGE_TIMER
    '  Description - This counter type measures the time it takes, on 
    '     average, to complete a process or operation. Counters of this
    '     type display a ratio of the total elapsed 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. The F variable represents the number of
    '     ticks per second. The value of F is factored into the equation
    '     so that the result can be displayed in seconds.
    '
    '  Generic type - Average
    '
    '  Formula - ((N1 - N0) / F) / (D1 - D0), where the numerator (N)
    '     represents the number of ticks counted during the last 
    '     sample interval, F represents the frequency of the ticks, 
    '     and the denominator (D) represents the number of operations
    '     completed during the last sample interval.
    '
    '  Average - ((Nx - N0) / F) / (Dx - D0)

    '	PERF_COUNTER_COUNTER
    '	Description	 - This counter type shows the average number of operations completed
    '		during each second of the sample interval. Counters of this type
    '		measure time in ticks of the system clock. The F variable represents
    '		the number of ticks per second. The value of F is factored into the
    '		equation so that the result can be displayed in seconds.
    '
    '	Generic type - Difference
    '
    '	Formula - (N1 - N0) / ( (D1 - D0) / F), where the numerator (N) represents the number
    '		of operations performed during the last sample interval, the denominator
    '		(D) represents the number of ticks elapsed during the last sample
    '		interval, and F is the frequency of the ticks.
    '
    '	Average - (Nx - N0) / ((Dx - D0) / F)

설명

열거형은 네이티브 형식에 직접 매핑되는 성능 카운터 유형을 지정합니다.

일부 카운터 형식은 원시 데이터를 나타내고 다른 카운터 형식은 하나 이상의 카운터 샘플을 기반으로 하는 계산된 값을 나타냅니다. 다음 범주는 사용 가능한 카운터 유형을 분류합니다.

• 평균: 시간에 따른 값을 측정하고 마지막 두 측정값의 평균을 표시합니다. 관련된 샘플 수를 추적하는 기본 카운터는 각 평균 카운터와 연결됩니다.
• 차이점: 이전 측정값에서 마지막 측정값을 빼고 차이가 양수이면 표시합니다. 음수이면 0을 표시합니다.
• 즉각적인: 가장 최근의 측정값을 표시합니다.
• 백분율: 계산된 값을 백분율로 표시합니다.
• 속도: 시간이 지남에 따라 증가하는 이벤트 수를 샘플링하고 작업 속도를 표시하기 위해 시간 변경으로 개수 값의 변경을 나눕니다.

성능 카운터 데이터를 샘플링할 때 평균을 나타내는 카운터 형식을 사용하면 원시 데이터 값을 사용할 때 의미가 있습니다. 예를 들어 원시 데이터 카운터 NumberOfItems64 는 샘플에서 샘플로 상당히 무작위인 데이터를 노출할 수 있습니다. 카운터가 반환하는 값의 평균 계산에 대한 수식입니다(X 0 +X 1 +...+X n)/n. 여기서 각 X i는 원시 카운터 샘플입니다.

속도 카운터는 평균 카운터와 비슷하지만 리소스를 사용할 때 속도가 증가하는 상황에 더 유용합니다. 평균을 빠르게 계산하는 수식은 ((X n -X 0)/(T n -T 0)) /frequency이며, 여기서 각 X는 카운터 샘플이고 각 T i는 해당 샘플을 가져온 시간입니다. 결과는 초당 평균 사용량입니다.

다중 타이머 카운터는 프로세서 또는 디스크와 같은 구성 요소의 둘 이상의 인스턴스에서 데이터를 수집합니다.

역 카운터는 구성 요소가 활성 상태가 아닌 시간을 측정하고 해당 측정값에서 활성 시간을 파생합니다.
