Script for Memory and CPU utilization

[M.sureshkumar]

Hi All,

We need script for Continuously monitoring the CPU utilization and Memory utilization on our HP unix 11.11 server.

Note:Glance command is not availble in our hp server.Pls guide me,how to install glance in our server.

Thanks&Regards,

You can write a shell script to run from cron which will have entries like

hour=`date +'%H'`
min=`date +'%M'`
uptime=`uptime`
load=`echo $uptime | cut -f2 -dl |cut -f2 -d: | cut -f1 -d, |awk '{print $1}'`
mem=`swapinfo -t |grep ^total | awk '{print $5}' | cut -f1 -d%`

echo "$load-$hour:$min" >> cpu_utilization.txt
echo "$mem-$hour:$min" >> memory_utz.txt

Hi Rajeev,

Thanks for your quick reply.

Our requirment is %of CPU utilzation and free memory at the same time i.e free memory in GB only.We need %of CPU utilzation and total and free memory in GB.

Pls modify the old script and provide new script for our requirment.

Regards,
Suresh.

#!/usr/bin/sh

DATE=$(date +'%D @ %T')
CPU=$(uptime | awk '{print $10}' | tr -d ',')
RAM=$(swapinfo -t | awk '/^total/ {printf "%2.2f GiB Avail\t%2.2f GiB Free\n",$2/1048576,$4/1048576}')
echo "$DATE\t$CPU\t$RAM" >> monitor.text

exit

You can install Glance from the Applications CDs or get the trial version here-> http://www.managementsoftware.hp.com/products/gplus/download.html

Here is a freebie with production time all over the world.

Here you go

hour=`date +'%H'`
min=`date +'%M'`
uptime=`uptime`
load=`echo $uptime | cut -f2 -dl |cut -f2 -d: | cut -f1 -d, |awk '{print $1}'`
mem=`swapinfo -tm |grep ^memory | awk '{print $4/1024}'`

echo "$load-$hour:$min" >> cpu_utilization.txt
echo "$mem-$hour:$min" >> memory_utz.txt

You'll have free memory in GB but with CPU load i have never come accross it displaying in %. Only values you can get in % format are system utilization (%SYS), user utilization (%USR), system idle (%IDLE)

Hi All,

Thanks,

We need small modification on that Script.

1.% of cpu --> Pls use the Glance command output
2.Available memory and Free memory ---> Pls use swapinf command output.

Pls modify the script for the above requirement in single script.

Regards,
Suresh.
