cprofilev

An easier way to use cProfile.

about

cprofilev runs and profiles a given python program and outputs a simple html view of the statistics collected.

See: http://ymichael.com/2014/03/08/profiling-python-with-cprofile.html on how to make sense of the profiled statistics.

installation

on most UNIX-like systems, you'll probably need to run the following `install` command as root or by using sudo

pip install cprofilev

quickstart

  1. Simply run your python program in with the -m cprofilev flag.
$ python -m cprofilev /path/to/python/program ...
  1. Navigate to http://localhost:4000 to view profile statistics of your python program (even while its still running!)

Alternatively you can output view cprofile output using the -f flag:

# NOTE this is cProfile not cprofilev
$ python -m cProfile -o /path/to/save/output /path/to/python/program ...
$ cprofilev -f /path/to/save/output

usage

usage: cprofilev.py [--version] [-a ADDRESS] [-p PORT] scriptfile [arg] ...

  -a ADDRESS, --address ADDRESS
                        The address to listen on. (defaults to 127.0.0.1).
