For graphical interface use ksysguard. If you want text or console based, try top

I think top is the command you are looking for.

mmm...confused.

i dont want graphical interface.

i would be happy, if i can capture CPU usage data in a log.txt file.

what is the command or what i should do ?

"top" just this is the command . if i type "top" will i get the data in a txt file ?

i need the datafile because i am interested to use that data file in another program.

Please can you explain more how do i solve this problem ?

if you do
root # top >> log.txt
its sending the data of "top" command in "log.txt"...........now see how you can use it

1.) This doesn't work. Instead, use: top -b
2.) Never, I repeat, never use the name of root if you do not absolutely have to.

top comand is working but i want the overall CPU usage . when i System Monitor , i found different CPU usage than using top command.

i want the CPU usage shown by the System Monitor . thats is a overall CPU usage.

how can i get that data ?
