A computer implemented method includes collecting, at a memory of a computing device having a processor, message processing latency information about processing electronic data transaction request messages over a timeframe by an application including a plurality of sequential stages; presenting, in a graphical user interface (GUI) rendered on a display coupled to the computing device, a digital dashboard, the digital dashboard displaying: for each stage, a stage box representing the stage positioned on a y-axis so as to represent a message processing latency associated with the stage over the timeframe; an inter-arrival message rate line positioned on the y-axis so as to represent an arrival rate between the electronic data transaction request messages over the timeframe; and an application box representing the application positioned on the y-axis so as to represent a message processing latency associated with the application over the timeframe; and in response to detecting a re-positioning of a stage box or the inter-arrival message rate line, displaying, on the digital dashboard, the application box at a different position associated with an expected message processing latency.
