In all our Windchill environments, we have many replica servers configured. The only way to get notified for any issues in replication is through end user's tickets. We shall have pro-active monitoring in place. For that there shall be a way to configure notifications for replication jobs/queue failures. OOTB JMX notifications does not have any option to get queue failure specifically. Neither PSM have that capability. Data replication being a daily and generic activity, is really crucial and must be monitored to keep end users and system happy.
