Measures reported by PSAppTuxQTest

The BEA Tuxedo message queuing servers provide for time-independent communication among clients and servers in a BEA Tuxedo application. They make it possible for an application, within a global transaction, to store client and server generated messages to stable storage for processing later. A client or server process involved in message queuing communications decides when it wants to retrieve a message off its queue.

Since too many enqueued messages can cause performance slowdowns, it is good practice to monitor the length of each message queue, identify overloaded queues, and initiate measures to reduce the load on the queue. The PSAppTuxQTest test provides these queue-level insights.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Servers_in_queue Indicates the number of servers that are currently connected to this queue. Number  
Queued_requests Indicates the number of requests that are currently in this queue. Number A low value is desired for this measure. A high value or a consistent incease in this value is indicative of server overload condition which in turn leads to the poor performance of the server.

Compare the value of this measure across the queues to identify the queue that is stacking the maximum number of requests thus overloading the servers.
