On June 9, 2011 IBM released Fixpack 1 of the Q Replication Dashboard v10.1.  Cool new features include an Alert Manager that sends e-mail messages when replication thresholds are breached (e.g. end-to-end latency exceeds 30 seconds).  After some tire-kicking, I will let you know if this is a viable substitute for the asnmon monitoring feature of Q Replication.  The dashboard has also been integrated with Tivoli Enterprise Portal.
