Field Description
TxProcess Sender Process
RxProcess Receiver Process
Cur Len The number of messages, in the sender process, waiting to be sent to the receiver process
High Mark The maximum number of accumulated messages (over the life of the queue), in the sender
process, waiting to be sent out to the receiver process
Time Out The time period the sender process waits for acknowledgement from the receiver process
before attempting to resend the queued messages
Retries The number of successive attempts (retries) the sender process will make to send the
messages to the receiver process
Msg Sent The accumulated number of messages sent between the sender and receiver processes
from the time the queue was created.
Ack Rcvd The number of acknowledgements received from the receiver process
Aval Retrans The current number of attempts, for retransmission, available in the event an
acknowledgement is not received. This value decrements on every retry and may fall
below the initial value, of “Max Retrans” to zero, in case the receiver is not responding.
This count is reset dynamically to Max Retrans value in case the queue starts to function
after experiencing some acknowledgement loss
Max Retrans The max number of retransmission attempts configured for a sender - receiver pair
