The Web Services Hub creates a log for status and error messages related to tasks, such as service initialization, task execution, and connection status. The logs include the IP address of the client, the service the client invokes, and the associated workflow. You can troubleshoot problems by examining error messages in this log.
You can view and configure the logs for the Web Services Hub on the Administrator tool.
The Web Services Hub also writes messages in the fault element of a SOAP response when it cannot process the request.
