Sigar是Hyperic-hq产品的基础包,是Hyperic HQ主要的数据收集组件。它用来从许多平台收集系统和处理信息.
这些平台包括：Linux, Windows, Solaris, AIX, HP-UX, FreeBSD and Mac OSX.
Sigar有C，C#，Java和Perl API，java版的API为sigar.jar sigar.jar的底层是用C语言编写的，它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
由于每个平台都要依赖.dll 所以的GitHub上发现了oshi
添加maven
