1. A computer-implemented method comprising: defining a scenario definition for a messaging scenario representing a subset of messages being exchanged at runtime via a message exchange infrastructure, the message exchange infrastructure comprising an adapter engine that performs at least one of converting a processed message from a first format of a sender application component to an internal format of the exchange infrastructure and converting the processed message from the internal format of the exchange infrastructure to a second format of a receiver application component, the scenario definition comprising a scenario condition specifying a state of one or more scenario attributes related to at least one of a message header and a message payload; evaluating the processed message to determine that the processed message is part of the subset of messages represented by the messaging scenario, the evaluating being performed while the processed message is in the internal format, the evaluating comprising determining that the processed message meets at least the scenario condition; receiving, via a user interface displaying a monitoring cockpit, a selection of the messaging scenario, the monitoring cockpit comprising one or more user interface elements selectable by a user to choose the messaging scenario from a plurality of scenarios defined for the exchange infrastructure; and displaying, in the monitoring cockpit in response to the receiving, a message status monitor showing an aggregated state of the processed message and all messages belonging to the messaging scenario and a message performance monitor showing aggregated performance data of the processed message and all messages belonging to the messaging scenario.
