how to check the performance of CPU and memory and disks on HP-UX 11.31

SanUX — Fri, 10 Feb 2012 06:13:09 GMT

Hi,

I am looking for some steps to troubleshoot the performance issue on HP-UX 11.31 running on blade servers.

High CPU and peak memory utilization are the common bottlenects. We need some guidelines on how to check the standards.

Is there any baseline of performance, please help me with the standards.

What is considered as normal performance as far as CPU and memory and disk is concerned.

How to find the process or threads occupying the resources? How to debug such scenarios?

Any help on this case is highly appreciated.

Thanks!

Regards,

San

Due you have glance installed? It is a good tool to measure performance.

There is also caliper that you can use when you need to look into process CPU details.

Hi ...

You can use:

Glace
top
sar
iostat

To check performance.

Cpu is easy if you have closer to 100% you have a problem. To check memory you need to see if the host is using swap ( swapinfo -tam ), check the process vhand if it is on the top it is a indicator of swap.

To check de i/o with disks use glance is a good tool compare the disks and check where de bottleneck is.
