Java JMX OperatingSystemMXBean

功能

OperatingSystemMXBean可以获取Java运行所在机器的操作系统信息：

• SystemLoadAverage: 系统负载
• Name: 机器名称
• Version: 机器版本
• Arch: 机器架构
• AvailableProcessors: 机器可用的CPU处理器

代码

public class OperatingSystemMXBeanTest {

    public static void main(String[] args) {
        OperatingSystemMXBean operatingSystemMXBean = ManagementFactory.getOperatingSystemMXBean();
        System.out.println("systemLoadAverage: " + operatingSystemMXBean.getSystemLoadAverage());
        System.out.println("name: " + operatingSystemMXBean.getName());
        System.out.println("version: " + operatingSystemMXBean.getVersion());
        System.out.println("arch: " + operatingSystemMXBean.getArch());
        System.out.println("availableProcessors: " + operatingSystemMXBean.getAvailableProcessors());
        System.out.println("objectName: " + operatingSystemMXBean.getObjectName());
    }

}
