Hi all, I'm now trying to port [gopsutil](https://github.com/shirou/gopsutil/) to NetBSD, and there is a `IOCounters` function to be ported, which is expected to fetch detailed io stats, like total reads/writes count/bytes, for each disks. It can be achieved by [/proc/diskstats](https://www.kernel.org/doc/Documentation/ABI/testing/procfs-diskstats) on Linux, and `hw.diskstats` on OpenBSD. But I couldn't find a equivalent on NetBSD. `iostat` looks promising but its outputs are quite limited and insufficient for this port need.

@"darkgeek"#p15478 `ioctlprint -l`?

@"darkgeek"#p15478 You can look at how it is done in the [Python project](https://github.com/giampaolo/psutil/blob/master/psutil/arch/netbsd/disk.c#L22) this is based on.

/proc/diskstats (Linux) or hw.diskstats (OpenBSD) alternative in NetBSD?

darkgeek ioctlprint -l?

pin Thanks, while ioctlprint -l gives me the detailed ioctl requests, the read/write counts/bytes are not there.

darkgeek What about https://man.netbsd.org/sysctl.8 and https://man.netbsd.org/sysctl.7 ?
