N3T_Appl_Reject_Conn_WorkSpike

Requests for new connections are not satisfied by this application because the connection backlog limit has been exceeded. Also, the number of currently active connections is a high percentage of the high water mark for the number of currently active connections, indicating a spike in application workload. An application workload spike likely prevented the z/OS application from completing the workload. To determine this, the following metrics in the Connections table are monitored:

This situation occurs if the active connections value is greater than the value for 90% of the high water mark and the backlog connections rejected value is greater than 0 (zero). A workload spike is likely the cause of the z/OS application being unable to complete its workload.

To resolve this problem, increase the application backlog queue limit or create an additional instance of the application.

Formula: Percent Active Connections >= 90 AND Backlog Connections Rejected > 0
