cpulimit is useful when you need to run a CPU intensive job and having free CPU time is essential for the responsiveness of a system.

Reply Link zhili wang October 11, 2007, 9:12 pmVivek,It is very helpful. How smart is the original Ridley Scott Xenomorph really? Or is it meaning the % use within a timeframe?Thanks Reply Link Will October 14, 2008, 7:01 amJust to add information to my question above. Use Linux’s built-in control groups, a mechanism which tells the scheduler to limit the amount of resources available to the process.

For example: ps jax --sort=uid,-ppid,+pid Sort ‘ps’ output by memory (RAM), from high to low Given that little piece of background information, here's how we can sort the ps command output why!!!!! I can see a block containing the CPU %user %nice %sys %iowait %irq %soft %steal %idle values. To use it, find out the PID of process hogging all the CPU time (using ps) and then run renice: renice +10 1234 Where 1234 is the PID.

Thanks for post. Is there some way to see memory utilization in the same file, memory utilization per process or as whole. I've trimmed down some of the output from the ps man page to show what I think the most important sort keys are. Kb_wrtn : Reports back the amount of data (kilobytes) from your measured interval that is written to the physical volumes.

Is there any way to find the Power/Energy consumed by the CPU/Disk/IOs. share|improve this answer answered Oct 31 at 15:45 PSN 1011 add a comment| up vote -2 down vote top -bn1 |sed -n '7,12'p works as a nice little one liner too.
