Queue statistics

The following table describes the queue statistical data returned by Process Administrator, the 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.

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.

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
RemainingQueued

Number of Work Items Remaining in Queue 

Number of Remaining Queued

Ending queue depth

Reports the number of remaining work items in the queue.

NumberOfSamples

Number of Samples

Number of Samples

Number of samples

Reports the number of samples.

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

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

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
