You can monitor messages on Data Capture and Delivery devices using the Edge Event Monitor tool.
The Edge Event Monitor is a standalone Java™ tool that runs on the same server as the WebSphere® Premises Server and connects to the MicroBroker on the edge controller as a MicroBroker client.
The Edge Event Monitor tool is located in the tools directory on the CD that contains the IBM® Data Capture and Delivery Toolkit for WebSphere Premises Server. For more information on how to use the Edge Event Monitor, refer to the PDF document, edge_event_monitor.pdf, in the compressed EdgeEventMonitor.zip file.
