Hi I'm writing a script to get overall system memory and cpu utilization in percentages, much like in top or with AIX's topas.
Could I use 'ps' to get the same, I know I can get such results for a particular or group of PIDs but I haven't been able to figure out how I could use 'ps' to give me general system wide stats.
Is there some other utility I could incorporate in to my script so that I may dump this info into a csv sort of file. This need to work on AIX 5.2 & 5.3
Thanks in advance.

Sorry for not answering for "ps" question, I don't have man pages installed on my aix boxes (I know, this is stupid), but I will recommend this tool for gathering such info - get the source code and build it, it's awesome tool, plus it has the csv reporting option that you asked about. If someone has thoughts to share for the "ps" question, I will be glad to learn it too.

if you have man pages in your system you look at this ;

vmstat 1 20 :gives virtual memory stats. 20 times 1 is the period (1 second)
or vmstsat 1 or else

ps -ef :gives systemwide resultsrocesses stats
ps aux :gives some other systemwide results rocesses stats
sar 1 1 or sar -P ALL etc sar gives cpu stats ( vmstat gives this information additionally to memory stats. But sar gives detailed info for all cpu )

netstat -v |netstat -D |netstat -i|netstat -r |netstat -in or etc.gives networtk stats

iostat 1 10 gives io stats

filemon gives filesystem stats

topas uses this underneath : sou you must read these from man pages

Hi, I'm looking into that tool sysgate, my corporate firewall (sonic) had it blocked so I'm in the process of getting that opened up, I'm quite interested from your description. I ended up using vmstat and iostat, though the better option would have been 'sar'. It relies on a few services to populate a file with sa1 and sa2, it's in the manual, unfortunately I couldn't get the time to configure it, I went with a simple script for the time being till the site opens up:
#!/bin/bash

# applabs.com

# Author: Siddharth Mody (siddharth.mody@gmail.com)

#===============START===============

ROOT_UID=0 # only users with $UID 0 have root privilages.

E_NOROOT=67 # Non-root exit error.

FILENAME=$1-${BACKUPDATE}".mem"



#check if root user.

# Run as root:

if [ "$UID" -ne "$ROOT_UID" ]

then

echo "Must be root to run this script"

exit $E_NOTROOT

fi;

testrun=$1;



# start timer

while true

do

read_time=$(date +%m.%d.%Y-%H\:%M\:%S);

# used and free memory pages of 4k chunks

avm=$(vmstat | awk '{print $3}' | tail -n 1);

fre=$(vmstat | awk '{print $4}' | tail -n 1);

cpu=$(iostat -s | awk '{print $4}' );

read -r -a array <<< $cpu;

cpu=${array[2]};

logdata=${cpu}","${avm}

mainheader="time,pcpu,pmem(4k chunks)";



if [ -f ${testrun}"_sysMon.csv" ]

then

:

else

echo "["$(uname -a)"]" >> ${testrun}"_sysMon.csv"

echo "${mainheader}" >> ${testrun}"_sysMon.csv"

fi

#log data into file

echo ${read_time};

echo ${read_time}","${logdata} >> ${testrun}"_sysMon.csv"

sleep 15

done

exit 0



If anybody could tell me how to manage that data extraction using awk with specifying line numbers I could get rid of all those read and tail statements.

Thanks for all the help so far, I really appreciate this forum.

Use PerfPRM tool by IBM, untar and use their scripts, either the main one or run them one at a time

PerfPMR is, strictly speaking, version specific but you may be able to parse the v5.2 and v5.3 releases and find common scripts to achieve your goal.
