I might be missing something, but I cannot find any IO stats for my discovered filesystems / disks (/dev/sda, etc.)

I've tried vfs.dev.read and vfs.dev.write, but these only return SPS on Linux which is kind of useless compared to some of the other OS disk perf support.

The most important ones I think to most people would be:

IOPS rate (block read/write per second)
IOP counter (blocks read/write total)
read/write sectors
read/write operations
read/write bytes

TARGETS: DISK, FS, PROCESS, RAM, etc.

When I try to use vfs.dev.read/write, It pulls SPS.

Again, I hope I'm not missing something and wasting your time here. But if any of these are missing, please consider adding them. Thanks for your time.
