springboot admin 监控hystrix
spring cloud提供了hystrix dashbord用来监控hystrix，但是既然springboot admin提供了单个应用的那么多好用的管理功能和监控，那么就整合在一起方便管理和查看吧。
springboot admin提供了spring-boot-admin-server-ui-hystrix用来整合hystrix。
动手试一试
基本项目结构如下图:
pom文件如下：
4.0.0
com.example
spring-boot-admin
0.0.1-SNAPSHOT
jar
spring-boot-admin
Demo project for Spring Boot
org.springframework.boot
spring-boot-starter-parent
1.5.6.RELEASE
UTF-8
UTF-8
1.8
Dalston.SR3
org.springframework.cloud
spring-cloud-starter-eureka
org.springframework.boot
spring-boot-starter-mail
de.codecentric
spring-boot-admin-server
1.5.4
org.jolokia
jolokia-core
de.codecentric
spring-boot-admin-server-ui-hystrix
1.5.4
org.springframework.boot
spring-boot-starter-test
test
org.springframework.cloud
spring-cloud-dependencies
${spring-cloud.version}
pom
import
org.springframework.boot
spring-boot-maven-plugin
build-info
除了eureka依赖和admin server依赖外，添加了admin server hystrix ui依赖，还有mail依赖用来发送监控报警
启动类:
package com.example.springbootadmin;
import de.codecentric.boot.admin.config.EnableAdminServer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
@SpringBootApplication
@EnableDiscoveryClient
@EnableAdminServer
public class SpringBootAdminApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootAdminApplication.class, args);
}
}
启动类需要添加@EnableAdminServer注解,本例是采用springboot admin整合eureka的方案自动发现所有的注册过的服务,所以添加了@EnableDiscoveryClient注解。
application.yml:
server:
port: 8400
spring:
application:
name: service-admin
mail:
host: smtp.163.com
username: [email protected]
password: xxx
properties:
mail.debug: false
mail.smtp.auth: true
boot:
admin:
notify:
mail:
to: [email protected]
from: [email protected]
# ignore-changes: UNKNOWN:UP
ignore-changes:
-
"*:UP" #从任何状态到up状态都不要发邮件通知
routes:
endpoints: env,metrics,dump,jolokia,info,configprops,trace,logfile,refresh,flyway,liquibase,heapdump,loggers,auditevents,hystrix.stream
eureka:
client:
serviceUrl:
defaultZone: http://peer1:8001/eureka/,http://peer2:8002/eureka/
management:
security:
enabled: false
info:
version: @project.version@本例还激活了邮件通知服务，所以pom中添加了mail starter,然后在yml中配置邮件服务器，spring.boot.admin.notify.main.to是要接收报警的邮箱，然后igore-changes的默认值我修改了一下从任何状态到UP状态的的状态变更都不要发送邮件通知，默认的只忽略了从UNKNOWN变为UP，我想从DOWN变成UP也不要发邮件了，只在不正常的时候提示就够了。然后指定了defaultZone为自己启动的eureka server的地址。admin 的routes endpoints在原来默认的基础上增加了hystrix.stream端点路由
logback-spring.xml:
照着官方配的，在admin ui界面上可以动态修改日志级别，比手动去调用actuator的接口要方便一些啦。
然后打包启动，就能看到admin 界面了:
打开某个服务的详情页：
选择hystrix页签看看:
其实和hystrix dashbord是一样的，只不过我们有一个统一的入口管理了，不像单独的dashbord散兵游勇一样。
这里admin是通过zuul智能路由到具体服务的hystrix.stream端点上去的，zuul有个BUG：https://github.com/codecentric/spring-boot-admin/issues/497
