PythonGitLinuxOSWindowsThe 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
