Java Sigar JNI收集硬件信息

Hyperic-Sigar是一个收集系统各项底层信息的工具集.他有如下特点:
1. 收集信息全面
收集CPU,MEM,NETWORK,PROCESS,IOSTAT等
使用Sigar,你完全可以模仿出cpuinfo,meminfo,top,free,ifconfig,ipconfig,netstat,route,df,du,ps,ls等多种unix平台和windows平台的指令.
2.跨平台,支持多数平台
支持的平台包括:windows系列(32系列,IA64系列,AMD64系列),linux系列,freeBsd系列,HPUnix系列,Sun solaris/Sparc/Sparc64系列,macOs系列,AIX系列等

3.提供的API接口全面
sigar本身由C语言开发而成,提供了丰富的API接口,包括:JAVA,.NET,PERL,PHP,PYTHON,RUBY.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……而Sigar.jar还依赖于jug-asl-2.0.0.jar、log4j-1.2.14.jar、Junit.jar，
