columns of perf report

perf report has five columns:
overhead - It indicates the % of overall samples collected in corresponding function.
command symbol - Process for which samples were collected.
name of ELf image
priviledge level
symbol level

But I don't understand how it calculates overhead & command symbol column.
Anyone who knows this in detail please help me out.
Thanks!
