Is there a way to send the debug data to 3rd party tools? Could you get the data to send to LabVIEW for instance to create your own logic analyzers?
Async Serial ("RS232") data is pretty widely accepted.
Semihosting allows you to read/write files on the Host via the debug interface.
Look at the tools in question (particularly LabView) to see what support they have; eg, OpenOCD; GDB; CMSIS-DAP; etc, ...
