Field Detail

TaskCompleteCount

static final String TaskCompleteCount

Count of all tasks completed by the service (failed + success).

IQueueCounters.ITaskCounters.TaskCompleteCount, Constant Field Values

AverageActiveCount

static final String AverageActiveCount

The #of tasks that are currently running (moving average).

Note: This count does NOT reflect the #of tasks holding locks for queues where tasks require locks to execute.

AverageQueueLength

static final String AverageQueueLength

The queue length (moving average).

Note: this is the primary average of interest - it includes both the tasks waiting to be run and those that are currently running in the definition of the "queue length".
