sar

[roger_101]

Hi

I'd like to use sar to generate a monthly report on CPU and memory utilization (and maybe smome other metrics).Does anyone have a cheat sheet on how to do this?

Thanks in advance for your reply.

Roger,

You could start with the man page for sa1. Things are pretty well explained there.

Dear Roger,

Try the below script.

#!/bin/ksh
#
#
LOGDIR="/tmp/stats"
LOGFILE="${LOGDIR}/sar_`hostname`.`date +'%d%m%y'`"

SARCMD=/usr/sbin/sar
SAROPTS="-udgpqr"

# Interval in seconds (5 minutes below)

INTERVAL=300

TOTALSECSINDAY=86400

NTIMES=`expr ${TOTALSECSINDAY} / ${INTERVAL}`

$SARCMD $SAROPTS -o $LOGFILE $INTERVAL $NTIMES >/dev/null 2>&1

With Regards

Harry

You can do both with vmstat


Or, install mrtg

http://people.ee.ethz.ch/~oetiker/webtools/mrtg/

Or - if you have perfview/glance installed:

From cron:

# performance
55 23 * * 1-5 /opt/perf/bin/extract -xp -r /home/gwild/zgbltemplate -g -b today 7:00 -e today 18:00 -f stdout | /bin/mailx -s 'svr100 performance report' gwild@mydomain.com >/dev/null 2>&1


# cat /home/gwild/zgbltemplate
REPORT "MWA Export on !SYSTEM_ID"

You could run the scripts I'm attaching for a time period you select via cron once a week.

In the root's crontab (ensure permissions/ownerships are OK) or the adm's crontab, put this entry. This will collect sys statistics q15min.
0,15,30,45 * * * * /usr/lib/sa/sa1

In the root's crontab I am parsing and converting the sa1 binary output to ASCII output to read the values.

56 23 * * * /var/adm/sa/get_sars 2>&1 > /dev/null

I am attaching the get_sars script. It will provide ASCII data q15min and put it into the directory structure listed in the script. Modify for your uses.

I have this generating daily but you can change to be monthly as your needs dictate.

Hi Roger,

If you spend some money, Glance+ pak (available as trial pack in Application CDs) can help you in quite a few ways. It can gather the data, report it (measureware) and you can view runtime performance (glance). If you go bit further, you can add Perfview to it that can be used to view data graphically both current and historical on multiple servers.

Also check 'sarcheck.com' for the tool sarcheck. It's available for a low price.
