AVAILABILITY
This command is available with the
SunView User's

[a manual with the abbreviation INSTALL]
for information on how to install optional software.
DESCRIPTION
perfmeter
is a SunView utility that displays performance values (statistics) for
a given
hostname.
If no host is specified, statistics on the current host are metered.
The
rstatd.8c
daemon must be running on the machine being metered.
When open,
perfmeter
displays a performance value in the form of a strip chart. When
closed, it displays a meter dial.
By default, the display is updated with a
sample-time
of 2 seconds.
The hour hand of the meter represents the average over a
20-second interval;
the minute hand, the average over 2 seconds. The default
value displayed is the percent of
CPU
being utilized.
The maximum scale value for the strip chart will automatically double
or halve to accommodate increasing or decreasing values for the
host machine. This scale can be restricted to a certain range
with the
-M
option.
OPTIONS
- -s sample-time
-
Set the sample time to
sample-time
seconds.
- -h h-hand-int
-
Set the hour-hand interval to
h-hand-int
seconds.
- -m m-hand-int
-
Set the minute hand interval to
m-hand-int
seconds.
- -M smax minmax maxmax
-
Set a range of maximum values for the strip chart. Values for
each of the arguments should be powers of 2.
smax
sets the starting maximum-value.
minmax
sets the lowest allowed maximum-value for the scale.
maxmax
sets the highest allowed maximum-value.
- -v value
-
Set the performance value to be monitored to one of:
-
- cpu

CPU
being utilized.

-
Ethernet packets per second.
- page
-
Paging activity in pages per second.
- swap
-
Jobs swapped per second.
- intr
-
Number of device interrupts per second.
- disk
-
Disk traffic in transfers per second.
- cntxt
