The Threshold Queues tab on Workload Management Analysis drilldown shows real-time information about the each threshold queue that the Workload Manager is currently managing in your current database. These queues are means of controlling workload resources. Rather than stopping activities or connections when too much work is executing in the workload, Workload Manager can assign these entities to a queue where they await their turn to run. Queues are established when the workload reaches certain user-defined thresholds that trigger queue creation.
The tab lists the threshold queues currently defined in your Workload Manager environment on the database. Expand a queue node to view the following summary statistics collected for the queue at each database partition:

To access in-depth information about a specific threshold, click its entry and view the following sub-graph:
Queue Size -- The number of activities or connections still existing in the selected queue at the time specified on the graph.
Queue Time -- At the time specified on the graph, the amount of time that the last activity to be removed from the queue resided in that queue.
