使用sigar.jar来监控系统的信息

使用sigar.jar来监控系统的信息。参考了http://blog.csdn.net/aoxida/article/details/8080492

首先要下载hyperic-sigar-1.6.4.zip，官网是http://sigar.hyperic.com/ 我在csdn上上传了资源http://download.csdn.net/detail/xdryhp164/8152133

然后把hyperic-sigar-1.6.4\sigar-bin\lib下面的sigar.jar加到项目的buildPath里面，如果是windows系统，再把sigar-amd64-winnt.dll放到环境变量的路径中，我在这里加到了我的C:\Windows\system32目录下。

package com.sigar.hp;
import org.hyperic.sigar.Cpu;
import org.hyperic.sigar.CpuInfo;
import org.hyperic.sigar.CpuPerc;
import org.hyperic.sigar.FileSystem;

import org.hyperic.sigar.Mem;
import org.hyperic.sigar.NetInterfaceConfig;
import org.hyperic.sigar.NetInterfaceStat;
import org.hyperic.sigar.Sigar;
import org.hyperic.sigar.SigarException;

/**

//磁盘IO

}
}
//网卡IO

System.out.println(name+":netstat:"+netstat);
}
}

public static void main(String[] args) throws Exception {

t.calcuate(sigar);
}
