借助Sigar API获取CPU相关信息

标签：

        Sigar（全称System Information Gatherer And Reporter，即系统信息收集报表器），它提供了一个开源的跨平台的收集计算机硬件和操作系统信息的API（该API底层接口用C语言编写），本文将演示如何借助Sigar API获取CPU相关信息：

package com.ghj.packageoftest;

import org.hyperic.sigar.Cpu;
import org.hyperic.sigar.CpuInfo;
import org.hyperic.sigar.CpuPerc;
import org.hyperic.sigar.Sigar;
import org.hyperic.sigar.SigarException;

public class CpuTool {

	public static void main(String[] args) throws SigarException {
		Sigar sigar = new Sigar();

		CpuInfo info = sigar.getCpuInfoList()[0];
		System.out.println("CpuInfo mhz：" + info.getMhz());
		System.out.println("CpuInfo vendor：" + info.getVendor());
		System.out.println("CpuInfo Model：" + info.getModel());
		System.out.println("CpuInfo cacheSize：" + info.getCacheSize());
		System.out.println("CpuInfo totalCores：" + info.getTotalCores());
		System.out.println("CpuInfo totalSockets：" + info.getTotalSockets());
		System.out.println("CpuInfo coresPerSocket：" + info.getCoresPerSocket());

		Cpu cpu = sigar.getCpu();
		System.err.println("CPU user：" + cpu.getUser());
		System.err.println("CPU sys：" + cpu.getSys());
		System.err.println("CPU nice：" + cpu.getNice());
		System.err.println("CPU idle：" + cpu.getIdle());
		System.err.println("CPU wait：" + cpu.getWait());
		System.err.println("CPU irq：" + cpu.getIrq());
		System.err.println("CPU total：" + cpu.getTotal());
		System.err.println("CPU stolen：" + cpu.getStolen());
		System.err.println("CPU softIrq：" + cpu.getSoftIrq());

		CpuPerc cpuPerc = sigar.getCpuPerc();
		System.out.println("CpuPerc user：" + cpuPerc.getUser());
		System.out.println("CpuPerc sys：" + cpuPerc.getSys());
		System.out.println("CpuPerc nice：" + cpuPerc.getNice());
		System.out.println("CpuPerc idle：" + cpuPerc.getIdle());
		System.out.println("CpuPerc wait：" + cpuPerc.getWait());
		System.out.println("CpuPerc stolen：" + cpuPerc.getStolen());
		System.out.println("CpuPerc softIrq：" + cpuPerc.getSoftIrq());
		System.out.println("CpuPerc combined：" + cpuPerc.getCombined());
	}
}
