Hello,
I'm looking for a way to gather statistics and interpret the result accordingly for a scale up or scale down decision process regarding CPU / cores.
So, basically:
* How can I gather statistics over a period of time as input for a decision process?
* How can I interpret them in an easy way, or are there any best practices on when scaling up / down CPU/Core wise makes sense (e.g. a particular statistic value is beyond a certain limit ...)
Any help is much appreciated.
Thanks,
Thomas

If I interpret your management speak correctly, you're trying to find out if you need a faster processor, or if you can save money on your licenses by downgrading to s slower processor.
Run Statspack for a 5-15 minute interval several times a day, and have a look at the wait events. If you are cpu-bound, you'll see 'CPU Time' cropping up as a significant part of your wait events.
