PERF_COUNTER_MULTI_TIMER_INV

  • Article

Applies To: Windows Server 2003, Windows Server 2003 R2, Windows Server 2003 with SP1, Windows Server 2003 with SP2

Description

This counter type shows the active time of one or more components as a percentage of the total time of the sample interval.

This counter type is an inverse multitimer. Multitimers monitor more than one instance of a component, such as a processor or disk. Inverse counters measure the time that a component is not active, and derive the active time from that measurement.

This counter differs from PERF_100NSEC_MULTI_TIMER_INV in that it measures time in units of ticks of the system performance timer, rather than in 100 nanosecond units.

Generic type

Percentage.

Formula

(B- ((N1 - N0) / (D1 - D0))) x 100, where the denominator (D) represents the total elapsed time of the sample interval, the numerator (N) represents the time during the interval when monitored components were inactive, and the variable B represents the number of components being monitored.

Average

(B- ((Nx - N0) / (Dx - D0))) x 100

Example

There are no counters of this type installed with Windows Server 2003 family.
