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

1         <dependency>
2             <groupId>org.springframework.boot</groupId>
3             <artifactId>spring-boot-starter-actuator</artifactId>
4         </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"
  }
}

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

二 定制断点信息

三 自定义健康状态指示器
