monitoring proccess by processor#

sugar2 · 02-13-2006, 06:34 PM

hi, how can I monitor my proccess by proccessor? i have a dell porweredge 4400 with 2 cpu's and with slackware 10.1 installed.
and i wish to know how they are used by the system.

Thanks in advance

On a Dual HT Xeon system, I use the top command to view the %CPU use.

Breaking this use down to the individual processes is not something I have ever thought of doing. Compiling the kernel is the most cpu intesive operation I ever do on a regular basis.

The only thing to i wish is to view that my linux its actually using the two proccessors and how.

cat /proc/cpuinfo

If you have two "processor" entries Linux sees them both.

In Slack, however, SMP is *disabled* by default, you'll need to
recompile your kernel.

that is what I got: does it mean my Linux its only using one or actually two?
thanks!

no sir, there's only one detected processor

tobyl · 02-14-2006, 01:13 PM

I only have one CPU, so I cant test it, but I read that top can be toggled through multiple cpu's by pressing "1" while it is running...

I see... how can I enable the seccond...?
I ran the partition utility of the server and everything its ok with both proccessors....

YES!!!

Thanks!

Now i see both
first of them is named CPU
and the other one is named CPU0

Thanks

Tinkster · 02-14-2006, 01:18 PM

Sorry mate, if you see a cpu0 (but not a cpu1) that still is
only ONE processor. The only difference is that CPU would show
the sum of both CPUs (but there's only one being detected), so
they'll always display the same info. And as I said in my first
response: you can't just go and "enable" it; you need to recompile
your kernel.

Do you recommendme to recompile the kernel... even if i can toggle between cpu and cpu0 in the top command?

can i recompile my kernel when i have 25 users connected to my samba server?

Thanks!

Tinkster · 02-14-2006, 01:35 PM

No, you can't "toggle" between CPUs. You can toggle between an
accumulated and a perCpu view, which will display the same stuff
with only one cpu picked up (you'd have to see cpu1 as well as cpu0
in the same screen if there were two).
I don't "recommend" anything. All I'm saying is that you won't use
both unless you recompile the kernel with SMP enabled ;)

Tink

Sorry chaps, I just managed to confuse the issue. Blame me!

Not at all :}
Your information was correct - albeit not helpful since
he didn't (or doesn't appear to have) read the man-page. ;}

Cheers,

liquidtenmilion · 02-14-2006, 03:47 PM

Well to be fair, he might not have known WHICH man page to read, since he may not have known that top is the command to display processes being ran.
