linux下用wmic监控windows

annhey 2014-06-10 04:22:04

在linux下安装wmic client for linux包后直接运行wmic -u adminuser%password //host 'select * from win32_operatingsystem'命令后可以获得相应系统信息。

但在java开发中把该命令放进Runtime.getRuntime().exec()中执行则返回Usage:[-?|--help] [--usage] [-d|--debuglevel DEBUGLEVEL] [--debug-stderr]类似的信息。

请问有没有在linux下利用java调用过wmic命令的，希望指点一下，谢谢。

最近也正在研究wmic client for linux，请问你在哪个linux 系统下安装的呀？有没有rpm的包，我想在fedora 20 上安装，但是只有deb的包，在这个系统上转化包的软件alien又安装不上，各种错误，第一次用linux系统，能不能指导一下，感激不尽啊

linux通过 WMI 对windows进行监控和管理，window不需要开启服务，Linux 安装wmic

后台实时监控服务器的CUP与内存占用率的场景很常见，虽然没做过，但是着手写代码之前我真没想到会花2个多小时才最终实现。网上虽然搜 PHP CUP 内存使用率这一类关键字出来的文章一大把，但大都是在Linux环境下，windows下只有提出靠cmd语句实现的观点，但少有实际直接可行的代码，辗转试了一遍 wmic , systeminfo 各种并不熟稔的cmd命令，并没有找到可行的方案，最终通过百度知道的一篇答案找到利用vbs获取的实现方式，稍加改善，可以在windows环境下直接使用。类代码 class SystemInfoWindows { /** * 判断指定路径下指定文件
