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 with the names	matching filter	will
	     be	displayed.  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.
