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



(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.


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


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