JFSstat is a tabular display of the filesystem statistics kept by Solaris. It uses the same kstats as the fsstat utility, and will only work on OpenSolaris Nevada build 35 or later, or Solaris 10 11/06 or later.
The available kstats are extensive, and only a subset can be displayed at any time. Use the "Show" menu to choose which set of statistics to display.
The rows can be sorted by selecting the column header.
The toolbar contains a small number of menus.
