Description This counter type is a multitimer. Multitimers collect data from more than one instance of a component, such as a processor or disk. Counters of this type display the active time of one or more components as a percentage of the total time of the sample interval. Because the numerator records the active time of components operating simultaneously, the resulting percentage can exceed 100 percent.

This counter type differs from PERF_100NSEC_MULTI_TIMER in that it measures time in units of ticks of the system performance timer, rather than in 100ns units.

Generic type Percentage
Formula ((N1 - N0) / (D1 - D0)) x 100, where the denominator
(D) represents the total elapsed time of the sample interval and the numerator (N) represents the portions of the sample interval during which the monitored components were active. They are multiplied by 100 to display the value as a percentage.
Average (Nx - N0) / (Dx - D0) x 100
Example There are no counters of this type installed with Windows 2000.
