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
