Queue statistics

The following table describes the queue statistical data returned by Process Administrator, Process Engine APIs, and vwtool. The first three columns denote the tools you can use to return the statistic, and the name each tool uses to reference the statistic. The last two columns provide the formula used in generating this data, and a brief description of the statistic.

Average
ProcessedWO
Average Work Items Processed Average Processed WOs Number of work items processed / Number of samples Reports the average number of work items processed during the period.
AverageQueueDelay Average Queue Delay Average Queue Delay Total queue delay / (Number of work items dequeued * Units) Reports the average length of time that a work item was in a queue prior to processing.
AverageQueueDepth Average Queue Depth Average Queue Depth Sum of queue depths for each sample in the period / Number of samples Reports the average number of work items in a queue during the sampling period.
AverageThroughput Average Throughput Average Throughput Number of work items queued / ((end time - start time) * Units) Reports the average number of work items queued.
AverageWOLocked Average Work Items Locked  Average WO Locked Number of work items locked / Number of samples Reports the average number of work items locked during the period.
AverageWO
ProcessingTime
Average Work Items Processing Time Average WO Processing Time (Work item servicing time + Work item aborting time) / (Number of work items dequeued * Units) Reports the average length of time taken to process a work item.
CurrentQueueDepth Current Queue Depth Current Queue Depth Current queue depth Reports the number of work items currently in a queue.
CurrentWOLocked Current Work Items Locked  Current WOs Locked Current number of work items locked Reports the current number of work items locked in the queue.
DequeuedRate Dequeued Rate Dequeued Rate Number of work items dequeued / Sample duration * Units Reports the rate at which work items left the queue during the sampling period.
EndTime End Time End Time   Reports the end time that was used for the evaluated request.
EvaluationTime Evaluation Time Evaluation Time   Reports the time at which this request was evaluated on the server.
InitialNumberOf
Queued
Initial Number of Work Items in Queue  Initial Number Of WO Queued Beginning queue depth Reports the number of work items in the queue at the beginning of the sampling period.
NumberOf

NumberOfUnits
InPeriod
Number of Units in Period  Number Of Units Number of units Reports the number of specified units (minutes, hours, days, weeks, months, or years) in sampling period.
NumberOfWO
Locked
Total Work Items Locked   Number of work items locked Reports the total number of work items that were locked during the period.
NumberOfWO
Processed
Total Work Items Processed WO Processed Number of work items queued + Number of work items aborted Reports the total number of work items processed during the period.
QueuedRate Work Items Queued Rate Queued Rate Number of work items queued / Sample duration * Units Reports the rate at which work items entered the queue during the sampling period.
QueueGrowth
Rate
Queue Growth Rate Queue Grow Rate Number of work items queued / Number of work items dequeued Reports the rate of growth of the queue for the sampling interval:If the number is greater than 1, work items accumulated in the queue during the sampling interval.If the number is less than 1, the number of work items in the queue went down during the interval.
QueueName Queue Queue Name   Reports the name of the queue for which you are collecting statistics.
Requested
EndTime
Requested End Time  N/A   Reports the end time requested by the user.
Requested
StartTime
Requested Start Time  N/A    Reports the start time requested by the user.
Requested
TimeUnit
Requested Time Unit  N/A   Reports the time unit type requested by the user.
StartTime Start Time Start Time   Reports the start time that was used for the evaluated request.
Summation
Duration
WOInQueue
Summation Duration of Work Items in Queue  Summation Duration WOs In Queue Duration work items in queue Reports the total time work items stayed in the queue before being processed during the sampling period.
SummationQueue
Depth
Summation Queue Depth Summation Queue Depth Total queue depth Reports the total queue depth during the sampling period.
SummationWO
Locked
Summation Work Items Locked  Summation Work Items Locked   Reports the total number of all work items locked in the queue for the samples in the interval.
SummationWO
Processed
Summation Work Items Processed Summation WO Processed Number of work items queued + Number of work items aborted Reports the total number of work items processed during the sampling period. Work items that have been queued or aborted are considered processed."Aborted" means that a user or automated process locked a work item but then unlocked it, rather than completing it.
TotalAbortedTime Total Aborted Time  Total Aborted Time Total aborted time Reports the total processing time taken by work items that were locked then unlocked without being advanced or updated during the sampling period.
TotalServiceTime Total Processing Time Total Service Time Total service time Reports the total processing time taken by work items that were locked and then advanced or updated during the sampling period.
TotalWOAborted Total Work Items Aborted Total WOs Aborted Number of work items aborted / Units Reports the total number of work items that were aborted during the period."Aborted" means that a user or automated process locked a work item but then unlocked it, rather than completing it.
TotalWODequeued Total Work Items Dequeued  Total WOs Dequeued Number of work items dequeued Reports the total number of work items that left the queue for processing during the period.
TotalWOQueued Total Work Items Queued  Total WOs Queued Number of work items enqueued / Units Reports the total number of work items that entered the queue during the period.
