How to retrieve Cache Bytes

Ninad Sarwate — Tue, 03 Jan 2006 10:45:20 GMT

What is the tool / command to retrieve the Cache Bytes?
Cache Bytes is the sum of the System Cache Resident Bytes, System Driver Resident Bytes, System Code Resident Bytes, and Pool Paged Resident Bytes counters.
Thanks.

Is this an HP-UX system? Those names do not sound familiar.

It is an HP-UX system. And yes, these are Windows counters.
I want the analogous counters in HP-UX.
I am not sure of the terminology too,so all the help will be appreciated.
Thank you.

Hello,

You can use NetIQ to setup these counters to collect data.

More information is at, http://www.netiq.com/

I need to do this using shell scripts and in-built tools and commands. Can't use third party tools.
Sorry not to have mentioned this before.
Thanks.

Hello, You can use HP-UX built-in commands like, vmstat, top to collect these details.

man vmstat
man top

for more details.

I am using vmstat and top for other things, but they do not have information about Cache.

You should do a man on pstat(2), specifically pstat_getvminfo() and maybe look at the header file /usr/include/sys/pstat/vm_pstat_body.h which lists some of the fields you can return. If this is the sort of info you are looking for, I'd be happy to post a short piece of C to get you started.

Try man sar, in particular "sar -b", might be what you need?
