Not too sure what you want - or why do it in C....

cpu stats available with built in HP-UX:

vmstat
top
glance

Do a man on those fore usage - easy to write a script to gather info.

Hi Geoff, thanks for your reply.
I want to write one C program to monitor the status of system resources, such as CPU, memory,disk,ect.
I wonder what tools I should choose, SIM, Sight manager, Service control manager or others.

Hi

HPUX has built in features for resource monitoring like top,vmstat,glance. There are also third party softwares which are available in the market.

Glance gives detailed output about the resource usage.

Hi,
If you are into C, and wish to write some C code then do a:
man pstat
You will find all you need...

Good luck

gtop is an open source tool for Linux. Its written in C or C++.

You can go get the source code and port it to HP-UX.

The reason people are recommending other tools, sar, top etc is the standard "been there done that got the tee-shirt" argument.

Most sysadmins see little reason to re-invent the wheel.

There may be some useful tools at http://www.hpux.ws/merijn

Well - here's one I found on ITRC - that does memory - maybe you can look at it and write one for cpu.
