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 Constant | Description |
|---|---|
| PERF_COUNTER_QUEUELEN_TYPEDecimal 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_TYPEDecimal 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_TYPEDecimal 5571840 |
Average length of a queue to a resource over time in 100 nanosecond units. |
| PERF_COUNTER_OBJ_TIME_QUEUELEN_TYPEDecimal 6620416 |
Time an object is in a queue. |
