An apparatus, system, and method are disclosed for the non-intrusive monitoring of business events on a middleware server. The steps to non-intrusively monitor business events on a middleware server include: monitoring business event traffic on a middleware server based on at least one business process probe that specifies an event and at least one business object attribute to be monitored; extracting data values associated with the specified attributes from the specified business event; storing the data values in a persistent data store; and present the data to the user. The monitoring does not alter the flow of existing business processes associated with the specified business event.
