SpringBoot1.x与监控(六)

由于2.x和1.x的监控不一样，此处先讲1.x

一 SpringBoot1.x监控

pom.xml

         <dependency>

             <groupId>org.springframework.boot</groupId>

             <artifactId>spring-boot-starter-actuator</artifactId>

         </dependency>

在配置文件application.properties中加入

management.security.enabled=false

info.app.id=hello

info.app=world #可以随意配置info开头的信息

当加入git.properties

git.branch=master

git.commit.id=xjkd33s

git.commit.time=2017-12-12 12:12:56

http://localhost:8080/info



{

  "app": "world",

  "app.id": "hello",

  "git": {

    "commit": {

      "time": "2017-12-12 12:12:56",

      "id": "xjkd33s"

    },

    "branch": "master"

  }

}

检查健康监控的时候，测试如下

加入redis的依赖

 <dependency>

            <groupId>org.springframework.boot</groupId>

            <artifactId>spring-boot-starter-data-redis</artifactId>

        </dependency>

配置(测试用，随便填的地址)

spring.redis.host=118.24.44.169

http://localhost:8080/health       ##会查出redis的信息

{

  "status": "DOWN",

  "diskSpace": {

    "status": "UP",

    "total": 322541973504,

    "free": 218147446784,

    "threshold": 10485760

  },

  "redis": {

    "status": "DOWN",

    "error": "org.springframework.data.redis.RedisConnectionFailureException: Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool"

  }

}

二定制断点信息

定制断点一般通过endpoints+端点名+属性名来设置。
- 修改端口id(endpoints.beans.id=mybean)
  
  修改结果：http://localhost:8080/mybean 要这样才能登陆
- 修改端口id(endpoints.beans.path=/bean)
  
  修改结果：http://localhost:8080/bean 要这样才能登陆
- endpoints.beans.enabled=false
  
  修改结果：http://localhost:8080/bean 无法登陆
- endpoints.enabled=false
  
  修改结果：所有的监控都无法登陆
- endpoints.beans.enabled=true
修改结果：http://localhost:8080/bean 只有这个能登陆
- management.context-path=/manage
  
  修改结果：访问要加路径/manage
- management.port=8181
  
  修改结果：访问的端口改成8181

三自定义健康状态指示器

编写一个指示器实现 HealthIndicator 接口

指示器的名字 xxxxHealthIndicator

加入容器中

package com.example.demo;



import org.springframework.boot.actuate.health.Health;

import org.springframework.boot.actuate.health.HealthIndicator;

import org.springframework.stereotype.Component;



@Component

public class MyAppHealthIndicator implements HealthIndicator {



    @Override

    public Health health() {



        //自定义的检查方法

        //Health.up().build()代表健康

        return Health.down().withDetail("msg","服务异常").build();

    }

}

测试结果：

http://localhost:8080/manage/health



{

  "status": "DOWN",

  "myApp": {

    "status": "DOWN",

    "msg": "服务异常"

  },

  "diskSpace": {

    "status": "UP",

    "total": 322541973504,

    "free": 218143944704,

    "threshold": 10485760

  },

  "redis": {

    "status": "DOWN",

    "error": "org.springframework.data.redis.RedisConnectionFailureException: Cannot get Jedis connection; nested exception is redis.clients.jedis.exceptions.JedisConnectionException: Could not get a resource from the pool"

  }

}
