Thanks for your reply, Pradeep. I am conducting my experiment on an Intel
Xeon E5530 (Nahalem architecture) processor, and the operating system is
Fedora 13 X86_64. Can I use perfmon on this platform?

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
