|Description||This counter type shows the active time of one or more components as a percentage of the total time of the sample interval. It derives the active time by measuring the time that the components were not active and subtracting the result from 100 percent by the number of objects monitored.
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 its 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 100ns units.
|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 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 2000.|
