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.
-B
- Endless batch mode. Same as batch mode, but does not exit after collecting
the first set of data.
-c
- Enable display of
geom(4)
consumers too. The default is to show statistics only for
geom(4)
producers.
-C
- CSV output mode. Implies endless batch mode, but output is in the form of
comma-separated values, with ISO 8601-like timestamps.
-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
).
-s
- Enable blocks' size statistics.
-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).
These commands are currently recognized if gstat
is not
running in batch mode:
<
- Halve the update interval.
>
- Double the update interval.
c
- Toggle display of
geom(4)
consumers.
f
- Display only devices with the names matching regular expression filter
(prompt for filter).
F
- Remove device filter.
q
- Quit
gstat
.
The gstat
utility exits 0 on success,
and >0 if an error occurs.
A gstat
utility appeared in FreeBSD
