How can I get the total CPU usage of a Linux machine with 1 or n CPU cores?
I am currently using the below method to extract CPU usage idle value from top command and subtracting the value from 100. Is this method correct and is there a better way to achieve the same.
Also, my linux VM is a stripped down version and has only few basic tools like top. Installing other tools is not an option as the package manager is also removed.
CPU_IDLE="$(top -bn2 | grep -F '%Cpu' | tail -n 4 | gawk '{print $8 $9}' | tr -s 'n:,[:alpha:]' ' '| gawk '{print $2}'),"

Yes, your method alright.
But, you could use mpstat to get more details.
It is included in sysstat package, and if you don't have it installed...
On CentOS / RHEL:
sudo yum install sysstat
On Ubuntu / Debian:
sudo apt-get install sysstat
Use bellow command if you don't have any permission to install a package
grep 'cpu ' /proc/stat | awk '{usage=($2+$4)*100/($2+$4+$5)} END {print usage "%"}'

You could extract adebpackage and copy files manually, or compile from source code.

Hey Rakib, looks like the command is not giving actual values. Yesterday ,I ran a script to log the CPU usage for almost 8 hours and I plotted a graph from the datapoints. However, it didn't match to the CPU history shown on my hyper visor for this linux VM.
