Sigar-硬件操纵&监控

1:Sigar用作windows/linux的硬件资源监控,可嵌入到Java程序中.

2: 下载地址: http://sourceforge.net/projects/sigar/files/sigar/1.6/

3: 下载后解压,将sigar.jar 及连接文件:

sigar-amd64-winnt.dll,sigar-x86-winnt.dll,libsigar-amd64-linux.so,libsigar-x86-linux.so

放到webapp\lib目录下

4:查看代码:

hyperic-sigar-1.6.4\bindings\java\examples\java

5:将代码复制到eclipse中执行即可.

示例代码:
