java获取服务器基本信息的方法

本文实例讲述了java获取服务器基本信息的方法。分享给大家供大家参考。具体如下：

利用第三方的jar包：（Hyperic-hq官方网站：http://www.hyperic.com） 通过Hyperic-hq产品的基础包sigar.jar来实现服务器状态数据的获取。Sigar.jar包是通过本地方法来调用操作系统API来获取系统相关数据。Windows操作系统下Sigar.jar依赖sigar-amd64-winnt.dll或sigar-x86-winnt.dll，linux 操作系统下则依赖libsigar-amd64-linux.so或libsigar-x86-linux.so
