Kernel size

Leonid Mishkind — Tue, 25 Sep 2007 07:58:20 GMT

Hi All.
My question to you is how do I know how much system resources HPUX Kernel takes. I want to have the results of Kernel threads usage only ( only what is compiled into the kernel ) , the minimum system resources of my servers.
I hope my question is clear enough.

Thanks to all.

Shalom,

You should install gpm/glance from your application cd's on a 60 day trail. gpm can give you a high water mark on kernel parameter actual system use.

It should be possible to drill into the menus and find useful information.

Shalom SEP.

I have glance/gpm on my system. But I did not find a way to split the information to kernel memory/CPU usage and User memory CPU Usage.

Leonid,

You can use kmeminfo to view the detail of kernel memory usage and user memory usage.

Use Glance to view CPU utilization

Here is an example of what you will get with kmeminfo.
