跨平台 获取系统信息的python库 http://support.hyperic.com/disp

The Sigar API provides a portable interface for gathering system information such as:

    * System memory, swap, cpu, load average, uptime, logins
    * Per-process memory, cpu, credential info, state, arguments, environment, open files
    * File system detection and metrics
    * Network interface detection, configuration info and metrics
    * Network route and connection tables

Linux Windows 都可以用
