Queue-length Algorithm Counter Types

Queue-length algorithm counter types increment the number of items in a queue at each sample interval as specified by the appropriate frequency property—Frequency_PerfTime, and so on. The cooked result divides by the number of samples to produce the average queue length.

An example is the AvgDiskQueueLength property in the Win32_PerfRawData_PerfDisk_LogicalDisk that uses the PERF_COUNTER_100NS_QUEUELEN_TYPE counter type.

CounterType ConstantDescription
PERF_COUNTER_QUEUELEN_TYPE

Decimal 4523008

Average length of a queue to a resource over time. It shows the difference between the queue lengths observed during the last two sample intervals divided by the duration of the interval.
PERF_COUNTER_LARGE_QUEUELEN_TYPE

Decimal 4523264

Average length of a queue to a resource over time. Counters of this type display the difference between the queue lengths observed during the last two sample intervals, divided by the duration of the interval.
PERF_COUNTER_100NS_QUEUELEN_TYPE

Decimal 5571840

Average length of a queue to a resource over time in 100 nanosecond units.
PERF_COUNTER_OBJ_TIME_QUEUELEN_TYPE

Decimal 6620416

Time an object is in a queue.
