Python中每个进程的CPU使用率 [英] CPU Usage Per Process in Python

问题描述

我是否可以查看当前python应用程序正在使用的处理器使用量(占最大值的百分比)?

Is it possible for me to see the amount of processor usage (% of maximum) that the current, python, app is using?

场景: 只要主机不消耗超过X％的CPU能力，我的主机就可以允许我运行我的应用程序，因此我希望它关注自身"并放慢速度.那么我怎么知道该应用程序使用了多少CPU?

Scenario: My host will allow me to run my app as long as it does not consume more then X% of the CPU power, so I would like it to 'keep an eye on itself' and slowdown. So how can I know how much CPU the app is using?

目标平台是* nix，但是我也想在Win主机上这样做.

Target platform is *nix, however I would like to do it on a Win host also.

推荐答案

>>> import os
>>> os.times()
(1.296875, 0.765625, 0.0, 0.0, 0.0)
>>> print os.times.__doc__
times() -> (utime, stime, cutime, cstime, elapsed_time)

Return a tuple of floating point numbers indicating process times.

摘自(2.5)手册:

times()

times( )

以秒为单位返回5个元组的浮点数，以指示累积的(处理器或其他)时间.这些项目是:用户时间，系统时间，儿童的用户时间，儿童的系统时间以及从过去的固定点开始按该顺序经过的实时时间.请参阅Unix手册页面times(2)或相应的Windows Platform API文档.可用性:Macintosh，Unix，Windows.

Return a 5-tuple of floating point numbers indicating accumulated (processor or other) times, in seconds. The items are: user time, system time, children's user time, children's system time, and elapsed real time since a fixed point in the past, in that order. See the Unix manual page times(2) or the corresponding Windows Platform API documentation. Availability: Macintosh, Unix, Windows.
