问题描述

根据这个与操作系统无关的问题，具体来说此回复，类似于可从点赞处获得的数据在 Linux 上的/proc/meminfo 中，如何使用 Python 从 OS X 读取系统信息(包括但不限于内存使用情况).

Following from this OS-agnostic question, specifically this response, similar to data available from the likes of /proc/meminfo on Linux, how can I read system information from OS X using Python (including, but not limited to memory usage).

解决方案

唯一可以从平台模块中获得非常好的东西，但它非常有限(cpu、操作系统版本、架构等).对于 cpu 使用率和正常运行时间，我认为您必须将命令行实用程序uptime"和vm_stat"包装起来.

The only stuff that's really nicely accesible is available from the platform module, but it's extremely limited (cpu, os version, architecture, etc). For cpu usage and uptime I think you will have to wrap the command line utilities 'uptime' and 'vm_stat'.

我为 vm_stat 构建了一个，另一个由你决定；-)

I built you one for vm_stat, the other one is up to you ;-)

import os, sys

def memoryUsage():

    result = dict()

    for l in [l.split(':') for l in os.popen('vm_stat').readlines()[1:8]]:
        result[l[0].strip(' "').replace(' ', '_').lower()] = int(l[1].strip('.
 '))

    return result

print memoryUsage()
