如何监控python程序中每个代码行的cpu使用率

Question

Is there any monitor utils that can monitor the cpu usage of every code line use in python program. I know profile,cProfile and line_profiler. but they are only statistic the time of each line or function using the cpu. If my program is io-intensive, it may be use a long time but doesn't really use the calculation of the cpu. So I want to find a util which could monitor the real calculation of the cpu. Have anybody an idea?

Answer 1

cProfile and profile both accept a time base function as a parameter. Just pass time.clock instead of the default time.time .
