Converts profiling output to a dot graph.
I get the error `Error: : syntax error in line 1 near 'digraph'` when running `gprof2dot -f pstats output.pstats | dot -Tpng -o output.png`
I have been using this with Linux's `perf` for a long time but recently I want the dot graph to show all of the four labels: ``` labels = {...
Lots of cases are, when simple module names are not enough to be able to differentiate them. A simple switch and if does the trick, as you already have this...

I encountered this when trying to run ``` gprof2dot -f pstats Traceback (most recent call last): File "/home/ajamato/.local/bin/gprof2dot", line 8, in sys.exit(main()) File "/home/ajamato/.local/lib/python3.9/site-packages/gprof2dot.py", line 3457, in main parser =...
[FlameGraph](https://github.com/brendangregg/FlameGraph) is another profiling visualization tool. It grokes a simple text-based line-oriented format. It ships with a series of `stackcollapse` scripts which generate the expected input from different tools (gdb,...
Currently, the timings on node labels are shown like this: `0.1234` It's not immediately clear that that's in seconds. Can we add a " s" to the label? Or maybe...
I have portion of a call graph that is defined by the union of two functions' call graphs. For example: ``` foo(): bar() baz() asdf(): fn1234() bar() fn9321() ``` Is...
By default when feeding oprofile data, it sums across all threads and presents a plot for that. However, in many multithreaded programs, this frequently points to the wrong place to...
I too am seeing this issue with 2 different (large) oprofile outputs. Commenting out the line fixes the problem, and produces dot files that can then be converted to png...
