soory. there was a typo error in my previous thread. sharing correct one now.
While checking the system utilization using sar command I have noticed below message.
Again running sar command after few minutes then the same message doesn’t appears
I am not sure what this message mean.
As, per my observation this message appears when system utilization goes high.
Regards,
scriptor

We have a script that uses
sar -u 1 10 | awk '/Average/ { print ( $2 + $3 ) }'
to get the CPU usage of a mutli engine machine. We think we are getting wrong information from the above string. We think it is adding up the total of the 12 engines and reporting back the total not the overall... (5 Replies)
Hi all,
With Sar, it gives you the CPU usage for the last x minutes etc, does anyone know if this is an average value when the machine in question has multiple CPU's, or simply just a reading of CPU #1?

Hi All,
I am trying to run sar on a Redhat server during a test I am performing for a couple of hours. I would like to get the sar metrics for every second (instead of the regularly set up 10 minute interval in the cron). What is the most efficient way to do this?
Thanks,

sag
sag(1) User Commands sag(1)NAME
sag - system activity graph
SYNOPSIS
sag [-e time] [-f file] [-i sec] [-s time] [-T term] [-x spec] [-y spec]
DESCRIPTION
The sag utility graphically displays the system activity data stored in a binary data file by a previous sar(1) run. Any of the sar data
items may be plotted singly or in combination, as cross plots or versus time. Simple arithmetic combinations of data may be specified. sag
invokes sar and finds the desired data by string-matching the data column header (run sar to see what is available). The sag utility
requires a graphic terminal to draw the graph, and uses tplot(1) to produce its output. When running Solaris 2.x and OpenWindows, perform
the following steps:
1. Run an "xterm" as a Tektronics terminal: prompt# xterm -t
2. In the "xterm" window, run sag specifying a tek terminal: prompt# sag -T tek options
OPTIONS
The following options are supported and passed through to sar (see sar(1)):
-e time Select data up to time. Default is 18:00.
-f file Use file as the data source for sar. Default is the current daily data file /usr/adm/sa/sadd.
-i sec Select data at intervals as close as possible to sec seconds.
-s time Select data later than time in the form hh[:mm]. Default is 08:00.
-T term Produce output suitable for terminal term. See tplot(1) for known terminals. Default for term is $TERM.
-x spec x axis specification with spec in the form:
name[op name]...[lo hi]
name is either a string that will match a column header in the sar report, with an optional device name in square brackets, for
example, r+w/s[dsk-1], or an integer value. op is + - * or / surrounded by blank spaces. Up to five names may be specified.
Parentheses are not recognized. Contrary to custom, + and - have precedence over * and /. Evaluation is left to right. Thus,
A/A+B*100 is evaluated as (A/(A+B))*100, and A+B/C+D is (A+B)/(C+D). lo and hi are optional numeric scale limits. If unspecified,
they are deduced from the data.
Enclose spec in double-quotes ("") if it includes white space.
A single spec is permitted for the x axis. If unspecified, time is used.
-y spec y axis specification with spec in the same form as for -x. Up to 5 spec arguments separated by a semi-colon (;) may be given for
-y. The -y default is:
-y"%usr0100;%usr+%sys0100;%usr+%sys+%wio0100"
EXAMPLES
Example 1: Examples of the sag command.
To see today's CPU utilization:
example$ sag
To see activity over 15 minutes of all disk drives:
example$ TS=`date +%H:%M`
example$ sar -o /tmp/tempfile 60 15
example$ TE=`date +%H:%M`
example$ sag -f /tmp/tempfile -s $TS -e $TE -y "r+w/s[dsk]"
FILES
/usr/adm/sa/sadd daily data file for day dd
