SpringBoot Actuator监控【转】

springboot actuator 监控

springboot1.5和springboot2.0 的actuator在启动日志上的差异就很大了.

springboot1.5在启动时会打印很多/XXX路径信息表示已暴露这些监控接口了, 而2.0是不一样的,2.0关闭了默认打印, 只能在trace日志级别查看,需要在application.yml中配置如下才可以正常输出web映射路径

springboot中使用actuator

pom.xml

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-actuator</artifactId>
    <version>一般无须指定版本,  如果不生效再指定版本即可</version>
</dependency>

引完后直接启动即可.

默认访问大部分接口时是需要权限的 , 只有访问http://localhost:8080/info不需要, 为了研究方便, 可以暂时在application.properties中关闭权限管理

management.security.enabled=false

/info

需要自己在application.properties里头添加信息，比如

  contact:
    email: xixicat@gmail.com
    phone: 0755-82890987

然后请求就可以出来了

修改监控属性

server.port=8080

#禁用监控端口的安全认证
management.security.enabled=false

#用于/info的监控访问
info.app.id=appid1
info.app.name=boboapp

#还能使用git.properties 以git.开头的属性, 暂未研究 git.xxx.xxx=yyy

#自定义/beans监控端点的名称,如果没有手动指明endpoints.beans.path则访问路径默认等于id同名路径
endpoints.beans.id=mybeans
#指定beans监控端点的访问路径成/my-beans, 所以不能通过/beans或/mybeans来访问了
endpoints.beans.path=my-beans


#关闭所有端点
#endpoints.enabled=false

#开启某个端点,它的优先级高于endpoints.enabled
endpoints.beans.enabled=true

#定制所有端点的访问根路径,最好是指定访问根路径,然后用security进行权限控制
management.context-path=/endpoints
#再起一个额外端口来使用监控管理功能,这时需要使用http://localhost:18080/endpoints/my-beans来访问端点,如果port=-1代表禁用管理端点
management.port=18080


#当在pom.xml中引入redis和actuator之后, 使用http://localhost:18080/endpoints/health,将能看到redis状态
spring.redis.host=localhost

在本地redis未启动时访问http://localhost:18080/endpoints/health

{
  "status": "DOWN",
  "diskSpace": {
    "status": "UP",
    "total": 520721788928,
    "free": 254064136192,
    "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"
  }
}

在本地redis启动时,访问 http://localhost:18080/endpoints/health 得到正常状态

{
  "status": "UP",
  "diskSpace": {
    "status": "UP",
    "total": 520721788928,
    "free": 254064136192,
    "threshold": 10485760
  },
  "redis": {
    "status": "UP",
    "version": "3.2.100"
  }
}

自定义监控

默认指示器都在spring-boot-actuator-1.5.21.RELEASE.jar包下, 如RedisHealthIndicator

要自定义指示器只需要添加一个HealthIndicator接口的实现类即可, 并返回Health对象

package com.example.actuator.indicator;

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() {
        int num = 1;
        if( 1 == num ){
            return Health.up().build();
        }else{
            return Health.down().withDetail("errorMessage","xx接口服务异常中").build();
        }
    }
}

此时访问 http://localhost:18080/endpoints/health 能看到myapp属性如下

{
  "status": "UP",
  "myApp": {
    "status": "UP"
  },
  "diskSpace": {
    "status": "UP",
    "total": 520721788928,
    "free": 254064111616,
    "threshold": 10485760
  },
  "redis": {
    "status": "UP",
    "version": "3.2.100"
  }
}

springboot2差异

在springboot2中

根路径/ 变成了/actuator

properties yaml

#actuator端口 
management.server.port=9001
#修改访问路径  2.0之前默认是/   2.0默认是 /actuator  可以通过这个属性值修改  
management.endpoints.web.base-path=/monitor
#开放所有页面节点  默认只开启了health、info两个节点
management.endpoints.web.exposure.include=*
#显示健康具体信息  默认不会显示详细信息  
management.endpoint.health.show-details=always

management:
  server:
    port: 9001  # Actuator 服务端口
  endpoints:
    web:
      base-path: /monitor  # 修改访问路径，2.0 之前默认是 /，2.0 默认是 /actuator，可以通过这个属性值修改
      exposure:
        include: "*"  # 开放所有端点，2.0 默认只开启了 health、info 两个端点
  endpoint:
    health:
      show-details: always  # 显示健康检查的详细信息，默认不会显示详细信息

http://localhost:9001/info

原为 http://localhost:9001/actuator/info

现为 http://localhost:9001/monitor/info
