Does anyone know how to use this feature

I have googled around and it may be that some specific code has to be inserted into the project, i.e. this is not a special type of breakpoint which allows you to printf some variables to some window in Cube IDE. But I am not at all sure... everything I found online seems a mess.
I have set up this dynamic printf and I see a load on debugger activity in the Console window, but no data comes out anywhere obvious.
More basically, I am looking for a way to set up a breakpoint so that it doesn't stop the program but increments a counter. Obviously, the program will be interrupted for some time (does anyone know how long?).
I have noticed there is an ignore count on a breakpoint and perhaps there is some way to monitor that, if it decrements. That must also pause the program, for however long the debugging system takes to process it. Do different debuggers affect this pause? I am using ST-LINK V2 ISOL.
I have also noticed ST-LINK V3 has a VCP (on an extra connector) so if one of the UARTs is wired to these pins, you could run Teraterm on the PC to receive any debugs sent to that UART. But that requires target code, obviously, and my target has a USB port already with a VCP on it so we can send printfs to that.
