The LoopBack Activity log provides a high-level overview of how IBM® Integration Bus interacts with LoopBack connectors by using the LoopBackRequest node.
When a LoopBackRequest node issues a request for an operation through a LoopBack connector, information is written to the activity log for successful and failed processing.
Activity log entries written by the LoopBackRequest node are not associated with a message flow and are not visible in the Activity Log Viewer in the web user interface; however, they are available when a configurable service of type ActivityLog is used to write your Activity logs to a file system.
