Is there a druntime/phobos function for getting the amount of memory (both, stack, malloc, and GC) being used by the current process?

I don't think so. But if you're on macOS you can use Instruments (shipped with Xcode) and pick the Allocations template.

Valgrind will tell you the exact usage (except no delineation for GC) per here:

Valgrind is an overall extremely useful tool for Linux devs.

Still, some internal instrumentation would be nice. But I'm not aware of any.

There are some runtime flags that can be passed to the executable when running it to get some info about the GC. Of course these are not documented (except perhaps in the changelog). I'm too lazy to try to find them now.

At least for the GC I remember using GC.stats and GC.profileStats to get some info.
