GSTAT(8)                FreeBSD System Manager's Manual               GSTAT(8)

NAME
     gstat -- print statistics about GEOM disks

SYNOPSIS
     gstat [-acd] [-f filter] [-I interval]

DESCRIPTION
     The gstat utility can be used to monitor I/O transactions of geom(4)
     devices.

     The options are as follows:

     -a      Only display providers that are at least 0.1% busy.

     -c      Enable display of geom(4) consumers too.  The default is to show
             statistics only for geom(4) producers.

     -d      Enable display of statistics for delete (BIO_DELETE) operations.

     -f filter
             A regular expression that can be used to only show statistics for
             some devices.  Only devices which name match filter will be dis-
             played.  The format of the regular expression is described in
             re_format(7).

     -I interval
             Refresh the gstat display every interval microseconds.  Adding a
             suffix of s, ms, or us (the default) indicates that the update
             interval is specified in seconds, milliseconds, or microseconds,
             respectively.

EXIT STATUS
     The gstat utility exits 0 on success, and >0 if an error occurs.

SEE ALSO
     systat(1), geom(4), iostat(8), vmstat(8)

HISTORY
     A gstat utility appeared in FreeBSD 5.0.

BUGS
     The gstat utility only works interactively.  It should probably detect
     when it is run non-interactively and produce simple ASCII text output.
     Otherwise, this utility should probably be folded into systat(1) which
     only works interactively and is the obvious utility to run for various
     other forms of system statistics.
