CPU占用率

调用ManagementFactory.getOperatingSystemMXBean()方法可以获取到系统CPU占用情况。

代码示例：

import Java.lang.management.ManagementFactory;
import com.sun.management.OperatingSystemMXBean;
 
public class SystemProperty {  
    public static void main(String args[]) {     
    OperatingSystemMXBean osmxb = (OperatingSystemMXBean) ManagementF
actory.getOperatingSystemMXBean();
    double cpuLoad = osmxb.getSystemCpuLoad();
System.out.println("cpuLoad: " + cpuLoad);      
} 
}

鲲鹏上执行结果：

[root@centos7 test]# java SystemProperty
cpuLoad: 0
