从 Python 中获取总内存/空闲内存 [英] Getting total/free RAM from within Python

问题描述

如何在 Python 应用程序中以跨平台方式获取系统的 RAM 总量以及当前可用的 RAM 总量?

From within a Python application, how can I get the total amount of RAM of the system and how much of it is currently free, in a cross-platform way?

理想情况下，空闲 RAM 量应仅考虑实际可以分配给 Python 进程的物理内存.

Ideally, the amount of free RAM should consider only physical memory that can actually be allocated to the Python process.

推荐答案

你试过 SIGAR - System信息收集者和记者?安装后

import os, sigar

sg = sigar.open()
mem = sg.mem()
sg.close() 
print mem.total() / 1024, mem.free() / 1024
