Performance Viewing

Jeff Hagstrom — Mon, 04 Nov 2002 13:18:38 GMT

We just added to processors to K460/9000. How can view the performance or the workload of all 4? Is there any way to force the box distribute the workload evenly over the 4 processors?

Jeff,

In a multi-processor system, the top command will show individual CPU's usage. Glance also has a CPU by processor screen. As far as forcing distribution - I don't think so - the system should distribute automatically.

You can also use sar to look at each CPUs performance.

Do a:

# sar -uM 5 5

to look at the performance for each CPU for 5 repetitions every 5 seconds.

Do a 'man sar' for more information.

There should be no action necessary to force distribution evenly.
The system is doing this by default.

sar -u -M should give you the relevant performance data

I don't think their is an OS setting that allows you to tweak the CPU load sharing of HP-UX. HP-UX does it automitically. I've heard you can write your own apps to utilise different CPU's.

You have to use HP PRM ( Process Resource Manager ) if you want ot force abd distribute the load evenly on all processors . PRM also has other cool features but is priced heavily and is licensed per cpu . But you might want to take a look at it .

Hi,

How can view the performance or the workload of all 4?
- you can use the Glance Plus to monitor the cpu in gui & character mode
SAM -> Performance Monitor

- you also can use the sar command to get the usage of the cpus. check out #man sar

- you also can use top command to check the usage for all the cpu. check out #man top

Is there any way to force the box distribute the workload evenly over the 4 processors?
Yes,
you can use the HP Process Resource Manager,

Hi

The easiest way is to do a sar -m , however if u ahve glance ( a trial 15 days version si avaialable ) which can give u the display at that moment , in case you are lok ing for a historical stuff then u need to ahve perf view installed which can be tuned to give the o/p cpu wise . there are also third party tools like sarcheck.com which can be useful i clooecting data over a period of time ( they use simple sar and ps commands to colelct data however the o/p is in html format in case u are intrested in such reports )

The unix system should do that automatically for you(distributing the processes to the CPU's).

I would prefer going for glance to monitor the CPU usage.
Glance has all the reports for the processor as well as the explanations for them.

Also using top should give you the CPU results.

Find out the top run processesi.e the processes that are catching the CPU for a long time.
This should give you a hint for the startup for the tuning of the system.

Thanks
