NAME
     gstat — print statistics about GEOM disks

SYNOPSIS
     gstat [-abcd] [-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.

     -b	     Batch mode.  Collect numbers, print and exit.  Default if stdout
	     is not a tty.

     -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.
