Collect numbers, print and exit. 51.It Fl c 52Enable display of 53.Xr geom 4 54consumers too. 55The default is to show statistics only for 56.Xr geom 4 57producers. 58.It Fl d 59Enable display of statistics for delete 60.Pq Dv BIO_DELETE 61operations. 62.It Fl f Ar filter 63A regular expression that can be used to only show statistics for some 64devices. 65Only devices with the names matching 66.Ar filter 67will be displayed. 68The format of the regular expression is described in 69.Xr re_format 7 . 70.It Fl I Ar interval 71Refresh the 72.Nm 73display every 74.Ar interval 75microseconds. 76Adding a suffix of 77.Cm s , ms , 78or 79.Cm us 80(the default) indicates that the update interval is specified in 81seconds, milliseconds, or microseconds, respectively. 82.El 83.Sh EXIT STATUS 84.Ex -std 85.Sh SEE ALSO 86.Xr systat 1 , 87.Xr geom 4 , 88.Xr iostat 8 , 89.Xr vmstat 8 90.Sh HISTORY 91A 92.Nm 93utility appeared in 94.Fx 5.0 . 95.Sh BUGS 96The 97.Nm 98utility only works interactively. 99It should probably detect when it is run non-interactively and produce 100simple 101.Tn ASCII 102text output. 103Otherwise, this utility should probably be folded into 104.Xr systat 1 105which only works interactively and is the obvious utility to run for 106various other forms of system statistics. 107
