The supplied command sar it probably what you are after. If you are after the value since last boot, just fire it off without parameters. Depending on your installation, you may get hourly or 5 minute stats, but it is averaged at the end. This is usually controlled by the running of sa1, often by the cron table of user account adm.
The columns are usually %usr %sys %wio %idle, so it's up to you to decide if you want 100-%idle or if I/O wait should be considered.
If this answers what you need, great.
If you need average at the moment, you can supply a variety of parameters. You could have
... which gets the information from the last 1 second. You can stretch this by increasing the first value. You can vary it by increaing the second value to show you more samples, e.g.
... will report the usage over the last 3 seconds 5 times and then an average.
There are also reports generated by sa2, again usually by the cron table of adm. Read your manaul pages about sa2 for where this file is likely to be in your implementation if you have it enabled.
hi,
AIX 5.3
For any command(say tar command) I am getting 100% busy for my hdisk.
But my CPU and Memory is not busy and have more idle also.
Please advice for any performance analysing.

Hi,
How can I find total CPU usage in percentage? e.g. if my system has 8 CPUs and I want to list total usage for all of them, is it possible through a command?
I have tried some of the commands like top, mpstat, sar. The output of those commands has to be manipulated to derive the percentage... (14 Replies)
Hi all,
Is it possible to get total memory usage and free memory usage without top? By Googling I found for total memory usage, use vmstat, for CPU, use mpstat, for disk I/O use iostat, is this correct? Will using sar gives the same result as ALL of these three (3) commands?
What about if I... (2 Replies)
Hi all
Can anyone advise/confirm whether total CPU usage when running sar is %user+%system+%iowait or is it %user+%system only?
I want to confirm whether I am having a CPU-bound problem or not.
This is a single-CPU VMware machine.

hi, i am using solaris server. I want to find the total CPU usage on a server. Top command will give that result, but here that command is not working. So anyone can help me to find the total CPU usage. (2 Replies)
Let's say i have 20 users logged on Server. How can I know how much memory percent used each of them is using with system time in each user? (2 Replies)

sar(1M) System Administration Commands sar(1M)NAME
sar, sa1, sa2, sadc - system activity report package
SYNOPSIS
/usr/lib/sa/sadc [t n] [ofile]
/usr/lib/sa/sa1 [t n]
/usr/lib/sa/sa2 [-aAbcdgkmpqruvwy] [-e time] [-f filename]
[-i sec] [-s time]
DESCRIPTION
System activity data can be accessed at the special request of a user (see sar(1)) and automatically, on a routine basis, as described
here. The operating system contains several counters that are incremented as various system actions occur. These include counters for CPU
utilization, buffer usage, disk and tape I/O activity, TTY device activity, switching and system-call activity, file-access, queue activ-
ity, inter-process communications, and paging. For more general system statistics, use iostat(1M), sar(1), or vmstat(1M).
sadc and two shell procedures, sa1 and sa2, are used to sample, save, and process this data.
sadc, the data collector, samples system data n times, with an interval of t seconds between samples, and writes in binary format to ofile
or to standard output. The sampling interval t should be greater than 5 seconds; otherwise, the activity of sadc itself may affect the sam-
ple. If t and n are omitted, a special record is written. This facility can be used at system boot time, when booting to a multi-user
state, to mark the time at which the counters restart from zero. For example, when accounting is enabled, the svc:/system/sar:default ser-
vice writes the restart mark to the daily data file using the command entry:
su sys -c "/usr/lib/sa/sadc /var/adm/sa/sa'date +%d'"
The shell script sa1, a variant of sadc, is used to collect and store data in the binary file /var/adm/sa/sadd, where dd is the current
day. The arguments t and n cause records to be written n times at an interval of t seconds, or once if omitted. The following entries in
/var/spool/cron/crontabs/sys will produce records every 20 minutes during working hours and hourly otherwise:
0 * * * 0-6 /usr/lib/sa/sa1
20,40 8-17 * * 1-5 /usr/lib/sa/sa1
See crontab(1) for details.
The shell script sa2, a variant of sar, writes a daily report in the file /var/adm/sa/sardd. See the OPTIONS section in sar(1) for an
explanation of the various options. The following entry in /var/spool/cron/crontabs/sys will report important activities hourly during the
working day:
5 18 * * 1-5 /usr/lib/sa/sa2 -s 8:00 -e 18:01 -i 1200 -A

The sar service is managed by the service management facility, smf(5), under the service identifier:
svc:/system/sar
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser-
vice's status can be queried using the svcs(1) command.
