The primary benefit of using EME for enterprise messaging is that all message transfer is monitored and controlled in one place. The EME Message Viewer is the gateway that shows exactly what is going on.

The EME Message Viewer allows you to take an inside look at the flow of messages on the ESB. A technician can "view" the content of an XML, EDI or other message that has been sent to or received from a trading partner and view sender, receiver, and transaction type. Using BIT-developed Mule interceptors, the movement of messages becomes visible using the Message Viewer. These interceptors audit the ESB correlation id so the exact steps in a flow can be retraced using the Message Viewer. The payload of messages can be optionally audited and then viewed using the Message Viewer. Metadata, referred to as message properties by the Mule ESB, is audited, in addition to the specific endpoint that the message touched. At each step of the integration, the components are logged, timestamped, and message properties are recorded. Where appropriate, a copy of the message content is captured for an absolute audit trail.

EME Message viewer capabilities:

• Login - form-based login and group/role-based security for every feature/page
• Message Viewer - view raw message body and raw header properties for all audited messages; also download the raw message body
• Search Screen - search a range of dates, by correlation id or endpoint
• JMS - upload a binary or text file to a JMS queue as well as set JMS properties on the JMS message, or view messages on a JMS queue
• Activity Monitor - view current memory consumption, and message counts per service; also configurable to probe raw TCP ports displaying status as up or down
• User Management - add new users, edit existing users, set group membership
• Event Log - filter events based on type; correlates messages to events so you can track which message caused which exception
