memory calculations

[suryanarayana_1]

Is there any simple script or utility in HP-UX to get peak and average memory utilization of the day.Write now iam using a script to collect free memory pages and calculating to get the above mentioned values.We don't have glance plus or measureware.This is the script iam using.

#!/sbin/sh
dd=`date +%b%d`
var1=`echo freemem/D|adb /stand/vmunix /dev/kmem|cut -f 2 -d :`
echo "The value of freemem is:"$var1>>/var/adm/memlog/freemem_$dd



Thank you.

There is a 60 trial of glance on your HP cds

I guess its almost same value you receive from
vmstat:
free pages -
In my case:
freemem = 65278 (x4,as 4k is a page size)
free vmstat column = 66811...

So you can use vmstat 60 for 1 min basis.
Again,checking free pages list is very-very rough of performance.

Thanks for your response.I forgot to mention,I kept that script in crontab and executing every minute.I would like to know what iam doing is write or wrong.

Hi,

a little off track, but:
if you have one or more cronjobs running every single minute you surely blow up /var/adm/cron/log
You might consider a cronjob moving/zipping/emtpying this logfile.
