Question

我是Spring Boot Actuator Metrics的新用户，我需要确定系统的CPU利用率。 / metrics url确实给了我其余的细节，但是systemload.average返回-1（如果加载平均值不可用，则返回-1）。你能让我知道我哪里出错了吗？我该怎么纠正它？我正在使用maven和Eclipse IDE（Mars）。我正在访问localhost本身的度量标准详细信息。网址为http://localhost:8080/details/metrics（用于上下文路径的详细信息）

这是我的代码： Application.java文件 package spring.boot.admin.actuator;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.PropertySource;

@EnableAutoConfiguration
@ComponentScan
@PropertySource(value = "classpath:application.properties")
public class Application{

public static void main(final String[] args) {
    SpringApplication.run(Application.class, args);
}
}

Answer 1

systemload.average返回JVM通过OperatingSystem MBean返回的内容（在java.lang树节点中可用）。在VisualVM中使用JConsole或VisualVM-Beans插件来查看返回的内容。

如果SystemLoadAverage属性的值相同，则Spring Boot中没有错误或使用Spring Boot。

Java Spring Boot Actuator Metrics系统负载平均值返回-1
