 .Sh NAME
 .Nm gstat
 .Nd print statistics about GEOM disks
 .Sh SYNOPSIS
 .Nm
 .Op Fl abBcdops
 .Op Fl f Ar filter
 .Op Fl I Ar interval
 .Sh DESCRIPTION
 The
 .Nm
 utility can be used to monitor I/O transactions of
 .Xr geom 4
 devices.
 .Pp
 The options are as follows:
 .Bl -tag -width indent
 .It Fl a
 Only display providers that are at least 0.1% busy.
 .It Fl b
 Batch mode.
 Collect numbers, print and exit.
 Default if stdout is not a tty.
 .It Fl B
 Endless batch mode.
 Same as batch mode, but does not exit after collecting
 the first set of data.
 .It Fl c
 Enable display of
 .Xr geom 4
 consumers too.
 The default is to show statistics only for
 .Xr geom 4
 producers.
 .It Fl C
 CSV output mode.
 Implies endless batch mode, but output is in the form of comma-separated
 values, with ISO 8601-like timestamps.
 .It Fl d
 Enable display of statistics for delete
 .Pq Dv BIO_DELETE
 operations.
 .It Fl f Ar filter
 A regular expression that can be used to only show statistics for some
 devices.
 Only devices with the names matching
 .Ar filter
 will be displayed.
 The format of the regular expression is described in
 .Xr re_format 7 .
 .It Fl o
 Enable display of statistics for other operations
 .Pq Dv BIO_FLUSH .
 .It Fl s
 Enable blocks' size statistics.
 .It Fl I Ar interval
 Refresh the
 .Nm
 display every
 .Ar interval
 microseconds.
 Adding a suffix of
 .Cm s , ms ,
 or
 .Cm us
 (the default) indicates that the update interval is specified in
 seconds, milliseconds, or microseconds, respectively.
 .It Fl p
 Only display physical providers (those with rank of 1).
 .El
 .Sh INTERACTIVE COMMANDS
 These commands are currently recognized if
 .Nm
 is not running in batch mode:
 .Bl -tag -width indent
 .It Ic <
 Halve the update interval.
 .It Ic >
 Double the update interval.
 .It Ic c
 Toggle display of
 .Xr geom 4
 consumers.
 .It Ic f
 Display only devices with the names matching regular expression filter
 (prompt for filter).
 .It Ic F
 Remove device filter.
 .It Ic q
 Quit
 .Nm .
