It looks like you are posting the same question from multiple accounts. :-(
Part of the reason you may not be getting an answer you like is because we don't understand the question. You need to be more specific. Are you talking about sampling results and Clockticks (CPU_CLK_UNHALTED) and Instructions Retired (INST_RETIRED.ANY) events (i.e., the default events)? The Clockticks event gives you a statistically accurate representation of where the processor is spending its time.
All events are documented in the online help, under the Reference book (see Help -> Contents).
