对CherryPy进行性能分析：将结果转换为图形格式

Question

I try to profile my CherryPy web server and as a result I have some .prof files. I can read them in text format by using web browser what was described in this post . But I need to export the results into a calltree to profile using, for example, KCacheGrind or Gprof2Dot.

But Gprof2Dot give me an error:

profile_results>gprof2dot.py -f prof out.prof | dot -Tpng -o out.png

error: unexpected end of file

And KCacheGrind doesn't know about .prof files...

Are there any ways to take a calltree in graphic format?

Thanks.

Answer 1

You need to use pstats.

gprof2dot -f pstats out.prof | dot -Tpng -o out.png

CherryPy uses python cProfile/profile.

Here is the reference on the docs
