I notice that there is much repetition in the x86 metric JSONs between CPUs.
So I know it's not the same as what you propose here, but jevents
standard arch events feature could be used to reduce the repetition.
I'm guessing that those metric JSONs are human generated, so would be
suitable; unlike the regular JSONs, which are automated.
Thanks,
