para-callgraph.stp - Callgraph Tracing with Arguments

Print a timed per-thread microsecond-timed callgraph, complete with
  function parameters and return values.  The first parameter names the
  function probe points to trace.  The optional second parameter names
  the probe points for trigger functions, which acts to enable tracing
  for only those functions that occur while the current thread is
  nested within the trigger.

$ stap para-callgraph.stp 'process("/bin/ls").function("*")' \
'process("/bin/ls").function("main")' -c "/bin/ls > /dev/null"
