check overall cpu usage
 

Dear all,

I wonder to know the command or the procedure to get the overall CPU utilisation in linux. I have used top, iostat, mpstat but the outputs are not the way i needed. Is it possible to get the output like...

CPU usage: .....% or something like that.

Thanks in advance.

Found this script Calculating CPU Usage from /proc/stat; saved it to a file, made it executable, and it worked.

It will give skewed results, though; he iterates over the entire line
"^cpu" and adds up values. Only the first 4 are actually relevant,
there's no point in adding softirq, irq, steal and such to the CPU.


Cheers,
