identify cpu hogs

edgjerp · 12-13-2004, 03:40 AM

Once in a while I get processes that consume virtually all cpu power. is there a simple way to identify which one? I know ps -A works, when you run it twice and compare the times of the various procs.

Sometimes my computer locks up completely, nothing works. not even changing tty and killing the hog proc. anyone know how to prevent this? the only solution I've found is a hard reboot.

If you can get "top" working in the console it's pretty easy to identify the bad program...

top is a good one to see the most active processes. ps -aux will give you more info than ps -A.

another place to check is to look in Mandrake Control Center->system->services. you may have services running that you don't know about, don't want, &/or don't need. use the info buttons to see what they are about. just be careful. some are neccessary for the system to function properly.

what is that?

anyone encountered programs that stall the system completely? if so, is there a way to prevent this from happening if you don't know what program this is?

open a terminal (or konsole in kde) as root & type top (hit enter). it will list the current running proccesses & show their memory, cpu, swap, etc. usages. you can get an idea from the output what the memory hog(s) might be.

also, did you look into services in MCC as i suggested?

You don't have to be root to view the active processes/services. You only have to be if you want to kill one.
