ZFS I/O stats per dataset

[da1]

Hello all,

Does anyone know of a way to get I/O stats on a per dataset basis? Couldn't find anything in the zfs(8) or nfsstat(1) manual.

This would come in handy if one would have multiple NFS exported datasets and would like to see which one is taking most/least of I/O.

You could use dtrace to get this information. I had written some scripts a few years ago. Maybe you can use them as examples.

Can you post them or maybe a link?

The link is in t1066's post: https://forums.freebsd.org/threads/sharing-of-dtrace-scripts.32855/#post-182070

The forums' link color strikes again
