Samples of all events (analysis type youchoose) will be collected respectively for their different intervals.
1. There is no mechanism to know other events after 1M instructions executed, because all events (including instructions retired) work independently.
2. The tool has timeline report at bottom of bottom-report, youmight select time range to zoom-in/filter results, you can verify if "instructions retired" is 1M, then observe other events data. Also you may redo or seek next 1M to 2M.
3. You meant that you can't changeSAV for some events. That is right! All SAVsin pre-definedanalysis typecan't be modified. Youmight create yourhardware event-based analysis to change SAVs, if like.
P.S>I assume that you are using VTune Amplifier XE 2011
