Stalled Queues KPI
The stalled queues indicator alerts you if messages are stuck for a long time or if messages are never retrieved from queues that are connected to clients.
A queue is considered to be stalled only if all these conditions are true:

A client is connected to the queue

Marginal Value | Critical Value | Maximum Value |
1 queue. | 50% of the maximum value. | Defined by whichever of these values is greater: ![*](chapterTOC_bullet.png) 1 queue. ![*](chapterTOC_bullet.png) 5% of the total number of client queues or forward queues in Brokers. ![*](chapterTOC_bullet.png) Current number of stalled queues. For example, if the number of stalled queues is zero, and 5% of the sum of client queues and forward queues is less than 1, then the maximum value is 1 queue. |
