Hi all,

Need Help for Script

Script will collect CPU Performance for every one minute(Thro'Schedule) if the CPU Perf. will go above 40%,it will send username,pid and hostname details to admin mail id

Pleas anyone help for this

Crude and dirty.

Put following in cron. Run it as you want.

UNIX95= ps -ef -o pid,ruser,pcpu,args|tr -d "%" |awk '{if($4>=90) print $0}' | mailx -s "processes takig more than 90% cpu in last scheduling interval" abc@xyz.com

The better method would be configuring a correct alarm in /var/opt/perf/alarmdef file. This would email you when thresholds are crossed. Check the examples in /opt/perf/examples/adviser directory.

Thanks a lot,

If any script to send alert mail like which user using more cpu util...above 60% and from which IP or Hostname

Change 90 to 60. It will show user name and processes name also. What hostname is going to be difficult, beacuse it depends upon what king of a process it is. Like sql, oracle listener processes come from network, while some are started on host itself.

May be if you can exaplain what you are trying to do, we may be able to help you better.

Sometimes CPU Utilzation is going 100% ,and we dont have any alert mail for this so
i think thro' script by schedule every minutes to check the cpu perf..
and if cpu utilization going beyond 40% send a mail alert to adminid with username and hostname details(which user using more
cpu utilization)

pls....

I have been using this for some time now to take a quick galnce at what is happening.

UNIX95= ps -ef -o pcpu="CPU %" -o ruser=USER -o pid,args|awk '{if($1>=40)print $0}'|sort -rk1|head -16

Hi,

Question what's the problem that a system has sometimes 100% CPU utilisation.
It's better to have a cpu runninig between the 70 en 90% then lower. If it hit sometimes the 100% it's only working. When also the swapspace en threads are filling up it's usefull to get an alert.
In the mean time with glance you can look wich process had needed the 100 % cpu.

Hi,
I've a script that by Glance collects the % of use for CPU, DISK, MEM and SWAP and notify me when 2 of them are over a threshold.
Let me know if you are interested in this and I'll provide you. (I'd like to avoid to post unnecessary script).
HTH,

Hi Aruturio,

If u dont hv any objection pls send it to me

Hi, this is the script.
It uses a glance syntax file: gln_syntax_file
in the same directory. It contains:
print "-- ",
gbl_statdate,
" ",
gbl_stattime,
" ",
gbl_cpu_total_util|3|0,
" ",
gbl_disk_util_peak|3|0,
" ",
gbl_mem_util|3|0,
" ",
gbl_swap_space_util|3|0

HTH,
Art

N.B. You have to adapt a bit teh script to your environment.
