Multiprocess debugging using multiple conventional debuggers

A computer system includes an aggregator network that couples a plurality of processes on which an application executes to a debugger user interface. Using the debugger user interface, commands are created and sent through the aggregator network to the processes and messages from the processes are routed through the aggregator network to the debugger user interface. Whenever possible, the aggregator network combines the processors' messages into fewer messages and provides a reduced number of messages to the debugger user interface. The aggregated messages generally contain the same information as the messages they aggregate and identify the processes from which the messages originated. The aggregator network examines the processor messages for messages that have identical or similar data payloads and aggregates messages that have identical or similar payloads.
