You need to address 3 problems using "native tools" (or any tools for that
matter).
1) Prior to SLES10, the CPU data is VERY WRONG. Easy to prove, and I keep
naively thinking
i don't need to keep reproving this. So you would be using PERL to get bad
data?
2) The overhead is an issue. You should target .1% of a CPU for instrumentation
of a Linux
server - this scales very well. I guess if your script woke up every hour to
collect bad
data, you could keep your overhead at .1%.
3) You want complete data. Hopefully for obvious reasons.
For a solution to these three problems:
Google "z/VM Linux capacity planning". See "WHYLPS.HTML".
Google "z/VM Linux chargeback". see the same.
Go to SHARE or GSE and ask the more successful installations what they do?
I could give more, but am already over edge of being blatant.

I just read this CMG paper: 'Monitoring Linux with Native Tools' by
Robert Anderson.
If your not a member I believe that the proceedings are publicly
available but you must register.
If not let me know...
Also if your a PERL programmer check out http://www.perfdynamics.com/main.html
Hope this helps.

Hi,
Some of our customer have an issue for accumulating their performance
data of Linux servers and z/VM. They wants to get the historical
performance data for Linux and z/VM itself. However the customers
don't have any budgets at the time, and they have only Performance
Toolkit, no other monitoring tools like OMEGAMON XE, ESALPS, etc.
Are there any ways to collecting and saving the performance data?
How does the other customers running Linux on their mainframe manage
the performance data for chargeback or planning for capacity?
Any help will be greatly appreciated. Thanks!
