gstat

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

NAME

     gstat -- print statistics about GEOM disks

SYNOPSIS

     gstat [-abcdop] [-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).

     -o      Enable display of statistics for other operations (BIO_FLUSH).

     -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.

     -p      Only display physical providers (those with rank of 1).

EXIT STATUS

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