--show-nr-samples::
|
|
Show the number of samples for each symbol
|
|
-T::
|
|
--threads::
|
|
Show per-thread event counters
|
|
-C::
|
|
--comms=::

with a '.' character, that thus it's the only non valid separator.
|
|
|
|
-g [type,min]::
|
|
--call-graph::
|
|
Display callchains using type and min percent threshold.
|
|
type can be either:
|
|
- flat: single column, linear exposure of callchains.
|
|
- graph: use a graph tree, displaying absolute overhead rates.
|
|
- fractal: like graph, but displays relative rates. Each branch of
|
|
the tree is considered as a new profiled object. +
|
|
Default: fractal,0.5.
