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

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
下面进行各个节点测试
http://localhost:8080/health { "status": "UP", "diskSpace": { "status": "UP", "total": 322541973504, "free": 218166931456, "threshold": 10485760 } }

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" } }
