Disclosed are embodiments that provide near real-time monitoring of a control application in a manufacturing environment to detect and determine the root cause of faults within the control application. The embodiments monitor the flow of data within the control application during events (i.e., transactions, stages, process steps, etc.). By comparing a dataflow path for a near real-time event with historical dataflow path records, dataflow interruptions (i.e., fails) within the control application can be detected. By determining the location of such a dataflow interruption, the root cause of the control application fail can be determined. Additionally, the invention can generate summary reports indicating the status of the control application. These summary reports can further be generated with drill downs to provide a user with direct access to the records upon which the reports were based.
