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
