I have the following script working fine, and need to generate a file delimiter (with tab or special character) for Excel data import. The script will run every hour in crontab to append the new rows to the delimiter, so that I can collect the data for i.e. a week, which will give me a lot of lines in the file.
Code:
#/bin/sh
tmpFile=/tmp/sartemp.out
sndFile=/tmp/sendfil.out
sysName=`uname -n`
#setup output file
date > $sndFile
# starting sar collection for cpu usage
sar -P ALL -o $tmpFile 1 3
#starting paging space information
echo "\n\n######################" >>$sndFile
echo "\n$sysName Paging Space information\n" >>$sndFile
lsps -s >>$sndFile
#starting memory collection
mmsize=`svmon -G|grep memory|awk '{print $2}'`
mminuse=`vmstat|awk '{print $3}'|tail -1`
#mminuse=`echo $memSvmon | awk '{print $3}'`
#mmfree=`echo $memSvmon | awk '{print $4}'`
#convert memory to MB
let "mmsize_a= ($mmsize)/256"
let "mminuse_a= ($mminuse)/256"
let "mmfree_a= ($mmsize_a -$mminuse_a)"
let "mmfreepercent=$((mmfree_a*100/mmsize_a))"
#
#format output
echo "\n\n######################" >>$sndFile
echo "\n$sysName Total Memory usage" >>$sndFile
echo "\nTotal Memory size: $mmsize_a MB" >>$sndFile
echo "\nTotal Memory inuse: $mminuse_a MB" >>$sndFile
echo "\nTotal Memory Free: $mmfree_a MB" >>$sndFile
echo "\nTotal Memory Free: $mmfreepercent%" >>$sndFile
#CPU usage information
cpusage=`sar -f $tmpFile | grep -p Average | awk '{print $2,$3,$4,$5}'`
cpu_usr=`echo $cpusage | awk '{print $1}'`
cpu_sys=`echo $cpusage | awk '{print $2}'`
cpu_wio=`echo $cpusage | awk '{print $3}'`
cpu_idle=`echo $cpusage | awk '{print $4}'`
#
#format output
echo "\n\n#########################" >>$sndFile
echo "\n$sysName CPU usage" >>$sndFile
echo "\nAverage CPU usage for User process: $cpu_usr%" >>$sndFile
echo "\nAverage CPU usage for System process: $cpu_sys%" >>$sndFile
echo "\nAverage CPU usage for I/O process: $cpu_wio%" >>$sndFile
echo "\nAverage CPU usage being idle: $cpu_idle%" >>$sndFile
echo "\n##################################" >>$sndFile
sysdate=`date +"%m/%d/%Y"`
systime=`date +%r`
cpucnt=`vmstat |grep lcpu |awk '{print $3}'`
pstotal=`lsps -s | awk '{print $1}'|tail -1`
psusedpercent=`lsps -s | awk '{print $2}'|tail -1`
This scripts gives me info like:
Code:
Total Paging Space Percent Used
71680MB 1%
Prod1 Total Memory usage
Total Memory size: 75776 MB
Total Memory inuse: 66925 MB
Total Memory Free: 8851 MB
Total Memory Free: 11%
Average CPU usage for User process: 56%
Average CPU usage for System process: 6%
Average CPU usage for I/O process: 9%
Average CPU usage being idle: 28%
The format I like to is:
Code:
Node Date Time Total_Paging_Space (MB) Percent Used(%) etc (in horizontal)
$sysName $sysdate $systime
Prod1 07/21/2011 01:00:00 AM 71680 1 so on so forth for Memory & CPU
Prod1 07/21/2011 02:00:00 AM 71680 3 so on so forth for Memory & CPU
Prod1 07/21/2011 03:00:00 AM 71680 2 so on so forth for Memory & CPU
Prod1 07/21/2011 04:00:00 AM 71680 4 so on so forth for Memory & CPU
Etc
Etc
Before appending the rows to the file, I need to do some tweaks.
The paging space data is from lsps –s, so I need to awk:
