NAME
gstat
- print statistics about GEOM disks
SYNOPSIS
[-acd
]
[-f filter
]
[-I interval
]
DESCRIPTION
The
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.
-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_format7.
-I interval
Refresh the
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.
The
utility only works interactively.
It should probably detect when it is run non-interactively and produce
simple
ASCII
text output.
Otherwise, this utility should probably be folded into
systat(1)
which only works interactively and is the obvious utility to run for
various other forms of system statistics.
