Specify output field - multiple keys can be specified in CSV format.
Following fields are available:
- overhead, overhead_sys, overhead_us, sample and period.
+ overhead, overhead_sys, overhead_us, overhead_children, sample and period.
Also it can contain any sort key(s).
By default, every sort keys not specified in -F will be appended
Default: fractal,0.5,callee,function.
+--children::
+ Accumulate callchain of children to parent entry so that then can
+ show up in the output. The output will have a new "Children" column
+ and will be sorted on the data. It requires callchains are recorded.
+
--max-stack::
Set the stack depth limit when parsing the callchain, anything
beyond the specified depth will be ignored. This is a trade-off
