Log file only records status and what you did with date, etc. Log file doesn't include performance data info, anymore.
If you worked on VTune GUI, open Bottom-up report after collecting data, select multiple lines (rows), then right-click to select item "Export to CSV.." togenerate .csv file. So you can open it without using VTune GUI.
Note that you may use "Grouping" funuctionin bottom-up report to select preferred thread ID, then select some functions under that thread.
