CPU utilization

[Luc MAIGNAN]

Hi,

I want to see and/or monitor cpu utilization. I have a server that have 
24 processors (6 processor x 4 core).

top only gives me global information for cpu, not per cpu (and core)

Is there a tool or a way to have these informations ?

Open source is the future. It sets us free.

top can show per CPU usage.

While running top interactively, press the 1 key to show individual CPU 
stats.

top can also sort by a variety of methods.

While running interactively, press F to show the sort menu.

top can also be run in non interactive mode to collect data over time to 
a file, which can be used to create trend analysis.

You may want to take a close look at top.

Probably the best/easiest trend analysis tool is: munin, right now.

Good Luck!

Hi,

atop works from the command line.  I believe you can
find a package for RHEL 5 here:

Hi,

to answer to both :

    * I 'm not using Fedora but RHEL 5, and no package is available
      including atop or htop
    * Like a server, it runs under level 3 not 5, so I need a command
      line tool

Hi,

using top you can have the utilization of each cpu, you just need to 
press 1 (the number 1) and then the top will unfold cpu usage.

Hopee this helps,
