# JFSstat

JFSstat is a tabular display of the filesystem statistics kept by illumos. It uses the same kstats as the fsstat command line utility.

The available kstats are extensive, and only a subset can be displayed at any time. Use the "Display" menu to choose which set of statistics to display.

The rows can be sorted by selecting the column header.

## The toolbar

The toolbar contains a small number of menus.

- File - allows you to exit jfsstat.
- Update every - allows you to change how rapidly the statistics are updated.
- Help - shows this help file, and the CDDL license that this software is licensed under.
- Display - allows you to select which statistics (in other words, which filesystem operations) are shown.
- Show - allows you to toggle the display of hidden filesystems and aggregates by filesystem type. By default, hidden filesystems and aggregates aren't shown.
