Spring 引导执行器未显示内存详细信息

Question

我正在尝试在 spring boot 2.0.2.RELEASE.

中实现执行器

依赖于 pom.xml

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-actuator</artifactId>
        <scope>compile</scope>
    </dependency>

application.properties

management.server.port = 8082
management.endpoint.health.enabled=true

自定义健康检查class

import org.springframework.boot.actuate.health.Health;
import org.springframework.boot.actuate.health.HealthIndicator;
import org.springframework.stereotype.Component;
@Component
public class HealthCheck implements HealthIndicator {
@Override
public Health health() {
    int errorCode = check(); // perform some specific health check
    if (errorCode != 0) {
        return Health.down()
          .withDetail("Error Code", errorCode).build();
    }
    return Health.up().build();
}

public int check() {
    // Our logic to check health
    return 0;
}
}

当我打 http://localhost:8082/actuator/health 在浏览器中，我得到 {"status":"UP"}

我希望得到

{
status: "UP",
diskSpace: {
status: "UP",
total: 240721588224,
free: 42078715904,
threshold: 10485760
}
}

Answer 1

在application.yml中添加以下内容

management:
  endpoints:
    web:
      exposure:
        include: '*'
  endpoint:
    health:
      enabled: true
      show-details: always
    info:
      enabled: true
    metrics:
      enabled: true
    threaddump:
      enabled: true

Answer 2

通过以下配置，我们可以启用所有组件的详细信息。

management:
    endpoint: 
        health:
          show-details: always

要单独获取内存详细信息，您可以指定组件。

 curl -i localhost:8082/actuator/health/diskSpace
    {
  "status": "UP",
  "details": {
    "total": 131574468608,
    "free": 47974543360,
    "threshold": 10485760
  }
}

Spring 引导执行器未显示内存详细信息

Spring boot actuator is not displaying the memory details
