anything /proc, is generally that of Linux. It is how that OS grabs values out of the kernel to regular useland usage.

macOS way tend to be sysctl. To see everything your system has, just run "sysctl -a". But it is rather a lot, you can
limit it a bit by just showing ZFS's kstat values, ie "sysctl kstat" which would include arcstats.

We used to ship a version of the cmdline tool arcstat, that uses sysctl, maybe that got lost in the new port?
