I live in germany as well, und bin auch von hier. I still can’t recall the last time an acquaintance or friend would ask me this without actually wanting to know the answer though. Albeit I do know the sort of meme way of asking “Läuft?” - “Muss muss” as well. But that feels more analogous to the english howdy, a way of asking the question entirely as a greeting.

The way Americans do it seems more like asking your friend "hey, wie geht’s dir denn so in letzter zeit”.
