PERF_100NSEC_MULTI_TIMER_INV

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. Counters of this type measure time in 100 nanosecond units.

This counter type is an inverse multitimer. Multitimers are designed to 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 the measurement of inactive time.

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 the Windows Server 2003 family.
