load vs CPU Utilization

Jonathan Grymes — Mon, 20 Apr 2009 13:38:59 GMT

I have HPUX 11.23 systems (foundation and enterprise operating env). Can you recommend HP tools to measure CPU utilization? Is there a way to correlate "load" vs CPU?

Hy,

You can use:

sar -u cpu%

sar -q queue length

sar -M Usage by cpu

you also have glance, but you need to purchase a license, you can download a trial version from HP.

Are you looking for command tools ?
If yes, use the below commands
#top
#glance

If you are looking for HP monitering tools. HP OpenView is a good enterprise class monitering tool.

Hi,

Use the below tools.

#top

#sar -u -> for cumulative cpu utilisation

#sar -Mu -> for individual cpu utilisation

#glance

All the above commands are used for the same

top and sar options will be there at the time of installation
but you have to purchase glance product ,a trial version of 30 days iss available in the hp softwares

in SAM you can monitor the same using the perfomance monitoring tool.

Glance is included in the Enteprise Operating Environment which is, as you say, on some on your systems. For the systems with FOE, use sar.

From sar, what does %usr (user mode) and %sys (system mode) equate to? Applications? Kernel?

Thanks in advance.

in practically ;
%usr+%sys+%idle=100%

also you can use xload to monitor system load in gui.

they are application and processes , kernel is on top for control purpose like interface I/O device with drivers .
