.Dd January 1, 2021 .Dt GSTAT 8 .Os .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.

p The options are as follows: l -tag -width indent t Fl a Only display providers that are at least 0.1% busy. t Fl b Batch mode. Collect numbers, print and exit. Default if stdout is not a tty. t Fl B Endless batch mode. Same as batch mode, but does not exit after collecting the first set of data. t Fl c Enable display of .Xr geom 4 consumers too. The default is to show statistics only for .Xr geom 4 producers. t Fl C CSV output mode. Implies endless batch mode, but output is in the form of comma-separated values, with ISO 8601-like timestamps. t Fl d Enable display of statistics for delete

q Dv BIO_DELETE operations. t 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 . t Fl o Enable display of statistics for other operations

q Dv BIO_FLUSH . t Fl s Enable blocks' size statistics. t 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. t 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: l -tag -width indent t Ic < Halve the update interval. t Ic > Double the update interval. t Ic c Toggle display of .Xr geom 4 consumers. t Ic f Display only devices with the names matching regular expression filter (prompt for filter). t Ic F Remove device filter. t Ic q Quit .Nm . .El .Sh EXIT STATUS .Ex -std .Sh SEE ALSO .Xr systat 1 , .Xr geom 4 , .Xr iostat 8 , .Xr vmstat 8 .Sh HISTORY A .Nm utility appeared in .Fx 5.0 .
