Display ZFS datasets' I/O in real time

Build Status Crates.io


ztop is like top, but for ZFS datasets. It displays the real-time activity for datasets. The built-in zpool iostat can display real-time I/O statistics for pools, but until now there was no similar tool for datasets.

Platform support

ztop works on FreeBSD 12 and later, and Linux.
