profiling - Visualize OProfile output with gprof2dot (incomplete output) -

So I'm not sure what I'm doing wrong I have a profile generated by oprofile I have this oprofile (that txt Looooots of lines in the file) Change the use of the following command for a text file:

  opreport -c --session-dir = dirname / oprofile_data / & gt; Profile_test.txt  

Here are some sample rows from the profile_test.txt file:

  ------------- - ------------------------------------------------- -------------- 768 2.2662 Liby-2.19.so __mcount_internal 768 100.000 libc-2.19.so __mcount_internal [self] --------------- - ------------------------------------------------- ------------ 718 2.1187 libc.2.19.so _int_free 718 100.000 libc-2.19.so _int_free [self] ----------------- - ------------------------------------------------- ---------- 694 2.0479 libc-2.19.so _int_malloc 694 100.000 libc-2.19.so _int_malloc [self] ------------------- - ------------------------------------------------- -------- 576 1.6997 libc.2.19.so malloc 576 100.000 libc.2.19.so malloc [self] --------------------- - ------------------------------------------------- ------ 565 1.667 2 NS3 :: LogComponent :: IsEnabled (NS3 :: LogLevel) Thirank 565 100,000 NS3 libns3-dev-core-debug.so libns3-dev-core-debug.so :: LogComponent :: IsEnabled (NS3 :: LogLevel) constants [own]  

This Nothing interesting.

Now I want to see it using gprof2dot. I run the script like this:

  ./gprof2dot.py -f oprofile --skew = 0.001 --stip profile_test Txt | Dot-tsvg & gt; Profile_graph.svg  

This generates a file, but there is nothing from profile_test.txt (this is missing all the function calls) and this is a time of call instead of a tree:

How can I make it better? With a tree structure? .

This is the allocation of real resources through:
