Hq的通过本地方法来调用操作系统API

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

 

• 通过JAVA API接口调用Sigar,获取系统信息的例子

1.先确定基本Sigar库
Sigar JAVA编程只是JAVA API编程,需要调用Sigar的基本库,因此需要把Sigar基本库放在对应的ClassPath下
注意:Sigar为不同平台提供了不同的库文件.典型的:
windows平台:sigar-x86-winnt.dll
linux平台:libsigar-x86-linux.so或
solaris平台: libsigar-x86-solaris.so或libsigar-sparc-solaris.so或libsigar-sparc64-solaris.so
64位平台:分为至强的libsigar-ia64-linux.so和AMD的libsigar-amd64-linux.so,sigar-amd64-winnt.dll

2. 程序代码
