Has anyone tried this? If so, was it fruitful?

Wind River already has it, now if we can just figure out a way to get them to include it for the FRC teams.
It's called data monitor (used to be called StethoScope).
Very easy to set and enable/disable monitor points, configure the sample frequency, set the buffer size, upload to host and (are you ready for this?) graph the data in Workbench.
This is exactly the kind of thing one hates to see programmers reinventing.
But if Wind River won't let you use it, and you need it, then you probably will end up doing it.
Yes, it will be fruitful/
