Mierzy czas w jednostkach znaczników czasomierza wydajności systemu. |
| Timer100NsInverse | 558957824 | Licznik procentowy, który pokazuje średni procent aktywnego czasu obserwowanego w interwale próby. Jest to odwrotny licznik. Liczniki tego typu obejmują procesor\% czas procesora. |
| CounterMultiTimer | 574686464 | Licznik procentowy, który wyświetla aktywny czas co najmniej jednego składnika jako procent całkowitego czasu interwału próbkowania. Ponieważ licznik rejestruje aktywny czas działania składników jednocześnie, wynikowy procent może przekroczyć 100 procent. Ten typ licznika różni się od CounterMultiTimer100Ns tego, że mierzy czas w jednostkach znaczników czasomierza wydajności systemu, a nie w 100 nanosekundach. Ten typ licznika jest wielogodzinnym. |

| AverageBase | 1073939458 | Licznik podstawowy, który jest używany w obliczeniach średniego czasu lub liczby, takich jak AverageTimer32 i AverageCount64. Przechowuje mianownik do obliczania licznika w celu przedstawienia "czasu na operację" lub "count per operation". |
| RawBase | 1073939459 | Licznik podstawowy, który przechowuje mianownik licznika, który przedstawia ogólny ułamek arytmetyczny. Sprawdź, czy ta wartość jest większa niż zero przed użyciem RawFraction jej jako mianownika w obliczeniu wartości. |
| CounterMultiBase | 1107494144 | Licznik podstawowy wskazujący liczbę próbek elementów. Jest on używany jako mianownik w obliczeniach, aby uzyskać średnią wśród elementów próbkowanych podczas wykonywania chronometrażu wielu, ale podobnych elementów.

' 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)
'
' Example - PhysicalDisk\ Avg. Disk sec/Transfer

Uwagi
Wyliczenie PerformanceCounterType określa typy liczników wydajności mapujące bezpośrednio na typy natywne.
Niektóre typy liczników reprezentują nieprzetworzone dane, a inne reprezentują wartości obliczeniowe, które są oparte na co najmniej jednej próbce licznika. Następujące kategorie klasyfikują dostępne typy liczników.
- Średnia: Mierzy wartość w czasie i wyświetla średnią z dwóch ostatnich pomiarów. Licznik podstawowy, który śledzi liczbę zaangażowanych próbek, jest skojarzony z każdym licznikiem średniej.
- Różnica: odejmuje ostatni pomiar z poprzedniego, a jeśli różnica jest dodatnia, wyświetla ją; jeśli ujemna, wyświetla zero.
- Natychmiastowe: Wyświetla najnowszy pomiar.
- Procent: wyświetla wartości obliczeniowe jako wartość procentową.
- Szybkość: Próbkuje rosnącą liczbę zdarzeń w czasie i dzieli różnicę w liczbie zdarzeń przez różnicę czasu, aby wyświetlić szybkość aktywności.
Podczas próbkowania danych licznika wydajności użycie typu licznika reprezentującego średnią może sprawić, że surowe wartości danych będą istotne dla Twojego zastosowania. Na przykład licznik NumberOfItems64 danych pierwotnych może uwidocznić dane, które są dość losowe z próbki do próbki. Formuła dla średniego obliczenia wartości zwracanych przez licznik to (X 0 +X 1 +...+X n)/n, gdzie każdy X jest nieprzetworzonym przykładem licznika.
Liczniki szybkości są podobne do średnich liczników, ale bardziej przydatne w sytuacjach, w których wskaźnik wzrasta w miarę użycia zasobu. Formuła, która szybko oblicza średnią to ((X i -X 0)/(T i -T 0)) / częstotliwość, gdzie każdy X i jest próbką licznika, a każdy T i jest czasem, w którym pobrano odpowiednią próbkę. Wynikiem jest średnie użycie na sekundę.
Liczniki multitimer zbierają dane z więcej niż jednej instancji komponentu, takiego jak procesor lub dysk.
Odwrotne liczniki mierzą czas, przez który składnik nie jest aktywny, i wyciągają z tego pomiaru czas, kiedy są aktywne.
Note
O ile nie określono inaczej, podstawa czasowa to sekundy.
Podczas instrumentowania aplikacji (tworzenia i implementowania niestandardowych liczników wydajności) możesz pracować z typami liczników wydajności, które opierają się na towarzyszącym liczniku podstawowym używanym w obliczeniach. Licznik podstawowy musi być natychmiast po skojarzonym liczniku w kolekcji CounterCreationDataCollection używanej przez aplikację. W poniższej tabeli wymieniono typy liczników podstawowych z odpowiadającymi im typami liczników wydajności.
